Suggested January 2024 8 Signs Your Smart Security System Has Been Hacked

How often do you check your smart security system? You hooked everything up, and unless something happens, you probably just assume everything’s working normally. But, what if it’s been hacked and it’s being used to spy on you? They could learn your routine and break in or see passwords and security codes as you enter them. They could even see extremely intimate details of your personal life. Check your system at least once a week for signs of a hack.

1. Cameras Are Repositioned

One of the most obvious signs your smart security system has been hacked is your cameras are repositioned. If they’re tilted or angled in any way that you didn’t do, disconnect them from the network immediately. It’s possible they were just physically bumped, but check your phone or computer to see where they’re facing. Also, ask if anyone else in the house might have changed them. Otherwise, hackers may be slightly adjusting your cameras to see better.

2. Unusual Traffic

This one’s a little trickier to check. Surges in network traffic may signal that a hacker is actively watching you through your security cameras. Some routers have built-in tools to let you monitor network usage. However, many don’t. You can check by accessing your router’s settings. Third-party firmware tools allow you to see the usage yourself. One of the most popular and compatible options is DD-WRT. If you want to see individual device usage, you’ll also need the additional monitor for DD-WRT called DD-WRT BBMON. Follow the documentation, which is provided on their respective sites, for the firmware and then monitor carefully.

Your ISP can also tell you if something isn’t right. If you don’t want to change your router’s firmware, contact your ISP. If they already provide data monitoring tools, use them to check for sudden spikes.

3. Indoor Indicator Lights

Sometimes it’s difficult to keep an eye on your outdoor camera lights. However, your indoor camera indicator lights are usually only on if they’re currently in use. If you don’t usually have your indoor cameras recording while you’re home, an indicator light means someone is watching you. It’s also possible your system is updating, but you can contact the smart security system company to double-check.

4. Login History Is Suspicious

To take control of your security system, hackers have to log in. Since you likely have an app that stays logged in all the time, you probably never check your login history. At least weekly, check for any additional logins. This is especially true if they come from different areas or devices. It’s sometimes a more subtle but clear sign something’s wrong.

5. Password Changed

The single most obvious sign your smart security system has been hacked is your password is changed. If you’ve just forgotten your password, that’s different. However, if you know for certain your password is correct, you’ve probably been hacked. Contact the security company immediately to reset your password and regain control. The company will also be able to tell you when the password was reset to ensure it’s not just your kids or friends messing with you.

6. You Notice Strange Sounds

If your security system has two-way audio, a hacker might accidentally give their presence away. While many are smart enough to mute their own mics, some don’t think about it. If you notice any odd sounds or human voices coming from your security system, you may have been hacked.

7. Footage Is Missing or Changed

For this one, the problem could just be issues with the system itself. Data might not have transferred correctly, or your local storage may be corrupted. However, if everything seems to be okay but the footage is missing or has been changed, a hacker is likely to blame. Of course, check with others living in your home to make sure they haven’t done it first. Scroll through your footage at the end of each week to check for any noticeable problems.

8. Issues with Other Devices

Your home network supports numerous devices. If one device gets hacked, all of your other devices are vulnerable too. This is also why it’s vital to use different passwords for different devices. For example, a hacker might just get your smart security system password but not your network password. They can control your system but not hack other devices yet.

If you notice other smart home devices, or even your computer or phone, are acting strangely, those devices might have been hacked. Look at everything, such as your thermostat and smart speakers. Issues mean your security system is at risk too.

Overall, these are relatively simple things to check. Turn these checks into a regular schedule for peace of mind and better home security.

Our Verdict

A great smart heating system for those that want to heat only certain rooms, but controlling every radiator and installing a thermostat in every room quickly becomes expensive.

Best Prices Today: Wunda WundaSmart





View Deal

WundaSmart is a name you’re almost certainly unfamiliar with in the world of smart thermostats. That’s because this is the Wunda’s first smart heating system, having spent years making underfloor heating systems.

Despite this, it’s come up with a brilliant product that does exactly what most people want from a smart heating system, primarily the ability to control temperatures in individual rooms and only heat those you want to heat.

That’s in contrast to the Nest Learning Thermostat – and others – which use a single thermostat and heat all rooms based on the temperature at a single point in your home.

WundaSmart isn’t the first smart heating system to provide room-level control – and kitting out your rooms will cost you a pretty penny – but in the long run it will undoubtedly save you money. And with energy prices rocketing, this approach is really starting to make a lot more sense than it used to.


Uses separate thermostat to TRVs for accurate readings

No data stored in cloud

Works if internet connection drops out

If you go for the most basic WundaSmart Starter Kit, which costs £199.99, you get a thermostat with a monochrome display, a smart TRV for one of your radiators and the HubSwitch which connects to your boiler.

WundaSmart HubSwitch with backplate

Jim Martin / Foundry

This compares reasonably well with the Nest, Hive and other thermostats.

But if you’re going to choose WundaSmart over the single-thermostat systems, you’ll want considerably more kit than that.

In order to control the temperature in specific rooms, you’ll need a smart Radiator Head for each radiator in those rooms, and one thermostat per room.

Jim Martin / Foundry

That’s because – sensibly – WundaSmart doesn’t record the temperature at the Radiator Head. Instead, it uses a combination of that temperature and the one measured by the room thermostat for a more accurate reading of how warm the room is.

You have a choice of two thermostats. You can go for the same thermostat as in the Starter Kit (£70) or a screenless version (below) for £50. The latter has no buttons so isn’t used for control: only measurement. It also has terminals for an optional floor probe if you want to measure the floor temperature. Both thermostats measure humidity as well.

This is a shame considering they aren’t cheaper than those rivals, but guests can at least increase or decrease the temperature without needing to ask the homeowner to adjust it in the app. Any changes last for two hours, unless they’re overridden by a change from another source: the app or your existing heating schedule.

The system supports up to 50 radiators and 30 rooms, which is plenty for homes and more than competing systems. It’s also partly aimed at office use, where those high numbers could come in handy.

As you’d expect, there’s also support for under-floor heating and a controller unit costs £99.95.

Schedules and geo-fencing

You can set up heating schedules in the app, per room, and there’s the option to use ‘adaptive startup’ which, instead of starting heating at the times you’ve chosen, the system will learn how long a room takes to reach temperature and will pre-heat to get it to that temperature by the times you’ve set.

You can use geo-fencing so that heating is turned off and on based on whether or not someone is at home. This avoids heating specific rooms when no-one is in them.

There are lots of options here, and you can set different rules for each room. You can register multiple phones so that, for example, when a teenager leaves the house, heating in their room is turned off. For communal rooms like the kitchen and lounge, you can choose what happens when the last registered user leaves, including “Set off until first User returns”.

Jim Martin / Foundry

In other words, don’t heat the kitchen until one of the family members returns home.

There are also choices for what happens when someone is back home: resume the heating schedule, go to Eco mode until the next scheduled heating period or set the Comfort mode until the next scheduled heating period.

Jim Martin / Foundry

Setting up geo-fencing can be quite confusing. First you need to register phones: otherwise the user list is empty and there’s no option there to add anyone. When registering, you can choose how far from home you need to be before you’re seen as “home” or “away” – the default is 0.3km.

Once set up, it works very reliably.

Modes and options

Near the top of the Home screen is Quick Switch. This allows you to override your schedule and change the temperature in all (controlled) rooms to Comfort, Eco, Reduced or Off.

Jim Martin / Foundry

You can choose a temperature for each mode, so you have full control over what each does. Plus, after choosing a mode, you then pick whether it will apply until the next change in the schedule or until someone manually changes the temperature.

Along similar lines is the Boost function. A bit like Hive’s similar feature, there are two buttons on the HubSwitch marked Boost 1 and Boost 2. In the app you can set what these do, which means choosing which rooms to heat and for how long. Then, when you press one of the buttons, those specific rooms will get heated to the Comfort temperature. You’ll just have to remember which rooms each button controls if you’ve set each differently.

Oddly, there are no virtual Boost buttons in the app which is a bit frustrating if, like mine, your HubSwitch isn’t easy or quick to access.

Energy-saving options include open-window detection.  This needs to be enabled for each room and will spot a temperature drop and automatically turn off radiators if it thinks a window has been opened. You can choose how much of a drop there needs to be (measured over two minutes) to activate this mode and how long to stop heating for.

Jim Martin / Foundry

Another is Holiday Mode which is buried deep in the settings and offers no explanation of what it does. You can set start and stop dates, but there’s a separate setting to turn Holiday Mode on and off manually.

Looking to the user manual, it “pauses your heating and hot water schedules until the end date. It will revert to antifreeze settings. If for any reason you want to turn on your heating or hot water during a holiday period, you can boost either for a period of time using the app.”

If you’re concerned about installing a wireless system, which this is, into a large home or period property with thick walls, the good news is that the radio “Seeker Signal” that WundaSmart uses offers a bigger range than Zigbee or Z-Wave – two commonly used alternatives.

The final feature of note is that none of your data is stored in the cloud. WundaSmart opts instead for storing that data locally, encrypted, “in your system”.

This also means that it will continue to work even if your internet connection goes down. But, naturally, you wouldn’t be able to control it remotely if that happened.


Professional installation recommended

DIY installation possible

The only room I couldn’t use it in was the bathroom which had a towel radiator with no TRV. Theoretically, it would be possible to fit a valve, but this would require a plumber and more expense.

As there’s no under-floor heating, I couldn’t test the Connection Box.

If not, and stuck-open valves are fairly common, you’ll need to try and fix them or have them replaced by a plumber.

I found around half my home’s radiators had the older M28 thread, but installing adapters took mere seconds: the kit includes various lengths of plastic pins so you can choose the one that fits best.

There’s no option to pay for professional installation when you order, so while WundaSmart recommends this, you’ll need to arrange a fitter yourself.

As the HubSwitch will attach to the common UK thermostat backplate, it is fairly simple to replace a traditional, dumb thermostat. However, if you do this, you’ll still need to check the wiring is correct to avoid damaging the HubSwitch. Plus, there are dip switches which need to set correctly for your heating setup, otherwise the system won’t work properly or at all.

Hopefully WundaSmart can update the app so there’s no ambiguity.

Once paired, I had no issues with connectivity apart from with two screenless thermostats going offline almost immediately. The problem turned out to be that one of the two batteries had fallen out of place, presumably when slotting the unit onto its backplate on the wall. WundaSmart is now aware of this and will – again – hopefully install a foam strip to keep the batteries firmly in place.


When I originally wrote this review it was July, precisely the wrong time of year to test a heating system in the UK.

But I’ve now spent a good few weeks evaluating it in winter.

The good news is that it works very well, living up to the promise of being able to control room temperatures individually.

Not only that: it largely manages to keep the temperature you’ve set very accurately, and you can see graphs of temperature and humidity, plus when the heating was on in that room, over the past week.

Jim Martin / Foundry

For the most part it is utterly reliable, too. There were only a couple of problems which the tech support team dealt with efficiently over email, with replies arriving relatively swiftly. There’s a phone number as well if you need more immediate support during office hours.

The issues appeared to be related to the RF signal, and caused the farthest radiators from the HubSwitch (around 60 feet away with several walls between them) to either turn on when they should have been off, or remain off when they should have been on.

Jim Martin / Foundry

The former was in fact cured by increasing the ‘downforce’ for that radiator head in the app, which exerts more pressure on the valve pin, ensuring it turns off and stays off.

The latter only happened twice and was resolved when the support team ran a recalibration at their end.

Dig into the room settings and you can see the rough signal strength for each thermostat and radiator head. I’m told that even the lowest report signal is still enough.

Unlike a single thermostat system where you can walk up to it and adjust the temperature, it’s more efficient to set up schedules with WundaSmart.

The interface for this is quite confusing at first, until you realise that the temperature (or Off) you’ve selected for that period is displayed above in smaller text, rather than highlighting the setting you just tapped on.

Jim Martin / Foundry

Adding multiple heating periods is easy, and you can set different temperatures for each if you want. You can then quickly copy that day’s schedule to other days, and other rooms, and edit them to remove heating periods, durations or temperatures.

The manual alternative means opening the app and tapping on each room individually to selecting a temperature and how long to heat that room for. This is easier if you only want to heat a couple of rooms.

There’s also the Quick Switch button at the top for setting all rooms to Eco, Reduced, Comfort or Off which can be useful, but is essentially the same thing as adjusting the temperature on a single thermostat system.

Compared to the Nest Learning Thermostat I was using before WundaSmart, I also found the information shown by the thermostats (with screens) to be rather basic.

Jim Martin / Foundry

They show the current temperature, but you have to press a button to see the ‘setpoint’, which is the temperature the room is being heated to or, as shown above, that it’s currently off.

There’s nothing to tell you at a glance whether the heating is currently on or not, and the E-Ink screens suffer from ‘ghosting’ which you can also see in the photo above where the temperature and humidity is still faintly visible.

You use the + and – buttons to adjust the temperature you want, which is good for guests who won’t have the app, and family members who don’t want to use it.

Put simply, I’d prefer it if they had displays like most rival smart TRVs.

The motors in the smart TRVs are relatively quiet, making less noise than those in the Honeywell EvoHome system.

It’s worth knowing that WundaSmart recommends you keep all internal doors closed for the system to work efficiently. Otherwise, the heat from one room could escape to a room or area you don’t want to heat.

The worst way to use the system, then, is to leave all the doors open and ask just one radiator to heat one room.

The other thing that WundaSmart can do is to control your hot water if, like mine, your heating system includes a separate hot water cylinder. It’s the same process as for central heating to set up a schedule for heating it.

As with a lot of smart heating systems, hot water control doesn’t feel particularly smart. It’s a simple on/off control and there’s no way to see in the app what the temperature of your water is.

If you want to know that, you’ll have to look at the cylinder itself, but often they have a basic thermostat that simply determines how hot the water is heated to, but does not show the temperature of the water inside.

Price & availability

WundaSmart is available in the UK, but you can also buy it and use it in any European country.

It isn’t available in the US, Canada, Australia or New Zealand.

The minimum you’ll need for it to work is the £199.99 Starter Kit, but as mentioned, if you’re only going to buy that, you could instead buy a cheaper single-thermostat kit.

For this review, five Smart Thermostats were installed and five Screenless Thermostats. Some rooms have two or three small radiators, which meant I needed 14 smart TRVs. Adding the Starter Kit, the total price was £1639.99.

However, if you have a total of 10 radiators and decide not to go for separate thermostats, the system will cost you £799.99.

It’s worth taking a look at Honeywell’s EvoHome system as well: some components (such as room thermostats and the UFH controller) are more expensive, but others, such as the Smart TRVs, are cheaper, despite having a useful LCD display.

It is, however, even more expensive than WundaSmart.

A cheaper option is Drayton’s Wiser system, which uses smart TRVs for room-level control.

The benefit with all these modular systems is that you can add to them over time. If you can’t afford an initial £1000+ outlay, you can begin with a starter kit and go from there when funds allow.

For more alternatives, read our roundup of the best smart heating systems.


WundaSmart may not be perfect but it is an impressive smart heating system that’s relatively easy to install and use. You could, if you’re competent, install the HubSwitch yourself, too.

The app could do with some finessing, particularly the pairing instructions, the screen for setting up each heating period, and it would be nice to have some virtual Boost buttons to avoid having to go to your boiler.

The screenless thermostats need special attention to make sure you don’t knock the batteries out of place while installing them.

Of course, the big question for many people considering such a system is how much it will save them on their energy bill. If you have no desire to save money, then you’d have to question the value of paying so much to control individual radiators and rooms.

WundaSmart quotes “up to 31%” savings, which is similar to rival systems. It’s almost impossible to calculate exactly how much you’d save because so many factors are involved, not least the fact that the weather is never identical from one year to the next. You can only use typical figures.

However, the fact that this system allows you to heat only the rooms you want to at the times you want them to be warm could well lead to significant savings over the next few years as energy prices continue to rise. You can find out more on WundaSmart’s website about whether turning off radiators really does save money.

Of course, you could go round your home turning radiators on and off manually throughout the day for free. But let’s face it, no-one wants to do that.

Stress And Sleeplessness Has Been A Problem Since The Victorian Era

So our concerns are evidently far from new. The Victorian era experienced not only the extraordinary upheavals of the industrial revolution, but also the arrival of gas and then electric lighting, turning night into day. The creation of an international telegraph network similarly revolutionized systems of communication, establishing global connectivity and, for groups such as businessmen, financiers, and politicians, a flow of telegrams at all hours.

Such shifts brought new patterns and expectations of work. By the 1860s the twin diseases of modernity—overwork and sleeplessness—became the focus of cultural anxieties. Victorian medical men warned against the dangers of sleeplessness. Drawing on this research, an 1866 article in the Spectator argued that sleeplessness was one of the “most annoying concomitants of civilized life”, but also one of the greatest threats to health:

Such concerns remain strong today. In his recent book Why We Sleep, the neuroscientist Matthew Walker highlights current medical findings on the threats to health from sleep deprivation, ranging from cancer, stroke, and heart failure, to Alzheimer’s, depression, and suicide tendencies.

Sally Shuttleworth and the Diseases of Modern Life team worked with the Projection Studio to create a light and sound projection onto the Radcliffe Humanities Building in Oxford, November 2023. Projection Studio

The brain-worker

The perils of sleeplessness are, of course, common to all. But the Victorians didn’t think so. Although the industrial classes had to work extraordinarily long hours, and were housed in poor conditions which must have affected their capacity to sleep, Victorian concerns about sleep were all focused on the professional classes, and that new creation of the period, the “brain-worker”. Sleeplessness was identified with overactivity of the brain, and hence the prime victims were believed to be those who laboured excessively with their brains, such as doctors, lawyers, academics, bankers, or politicians.

There was also considerable concern about schoolchildren being forced to labour long into the night on their homework, thus curtailing their sleep, with many doctors and social reformers calling for a scrapping of the “payment by results” system (which linked a school’s funding to the success of its pupils in examinations), and the creation of more healthy and sleep-friendly regimes of education. In his wonderful work, Hurry, Worry and Money: the Bane of Modern Education (1883), the Leeds physician Pridgin Teale inveighed against the new competitive system of education which destroyed the health and moral well-being of pupils and teachers alike, leaving them exhausted and demoralized.

As this suggests, our own social problems with addiction to sleeping pills have their parallels in the Victorian age. Chloral quickly became a drug of choice, as our clergyman suggests. It was associated with numerous high-profile deaths, from the artist and painter Dante Gabriel Rossetti to the scientist John Tyndall (who died when his wife gave him an accidental overdose).

In one case, a Cambridge classicist, burdened with too much examining, took to chloral and ended up taking his own life. Such examples were widely publicized in books on the wear and tear of modern life.

Counting sheep

The Victorians were acutely aware of the relationship between the new social conditions, technologies and work practices, and the problems generated for health (although their concerns were admittedly largely focused on the upper echelons of society).

In the 20th century, with increasing specialization in areas of medicine and science, that sense of technology’s interconnection with and impact on society was often lost. But recent research is recovering that balance. Overwork and lack of sleep, the Victorians argued, could lead to an early grave. Although such claims were often seen as too alarmist at the time, current sleep science has now endorsed that position. Too little sleep might indeed kill you.

Application Has Been Blocked From Accessing Graphics Hardware In Windows 11/10

Many a time it may so happen that programs on your Windows 11/10 PC get denied of accessing graphics hardware. The message says that an Application has been blocked from accessing Graphics hardware. One of the common scenarios is when your PC is stuck for some reason when playing a game. This somehow misconfigures the driver, and when an application tries to access the graphics driver, it just fails. In this guide, we share how you can fix Application that has been blocked from accessing graphics hardware error.

Application has been blocked from accessing Graphics hardware

In my experience, the problem majorly happens where the driver is not compatible with your existing Windows 11/10 version, and mostly fails to post a major update. This causes the GPU to take more time to respond to graphics requests and mostly fails. Let’s take a look at the possible solutions.

1] Uninstall and Re-install the graphics card driver

This is the first thing you need to try. Many a time the drivers downloaded from the Windows Update misconfigures. The best way is to download the latest drivers from the OEM site. You will need to search on the website using the details of your graphics card name. Check out our post on Uninstall and reinstall the drivers. When installing the driver, make sure to run the program compatibility mode for Windows 11/10.

2] Run the Hardware Devices troubleshooter

3] Give access to graphics hardware to applications Windows 11

In Windows 11, you can select which apps can use your graphics hardware. By default, this option is set to Power Saving mode where Windows decides the Graphics preference for different apps. But if you want, you can change this setting. The following steps will help you with that:

In the Settings app, make sure that you have selected the System category on the left side.

Windows 10

Windows 10 Graphics settings allow you to dedicate applications to use a graphics card. This will work if you are having a problem with specific applications accessing graphics hardware. It works for both WIN32 Applications and Apps from the store.

Read more about using Graphics settings in Windows11/10.

4] Disable TDR checker

TDR stands for Timeout Detection and Recovery. This feature first appeared in Windows Vista and then has been there till Windows 11/10. The system is built to recover system graphics when the OS fails to receive a response within a certain amount of time. The default is set to 2 seconds.

It may so happen that graphics card takes more time because of an intensive task, and OS feels there is some problem and restarts the graphics as a recovery method.  The solution which we are suggesting now increases the TDR time to more than 8 seconds. This gives more window for OS to react.

Exit all the applications on the PC.

Type regedit on the search box, and launch it with admin privileges.

Browse to:

HKEY_LOCAL_MACHINESYSTEMControlSet002 ControlGraphicsDrivers or HKEY_LOCAL_MACHINESYSTEMControlSet001 ControlGraphicsDrivers

Whichever is available – depending on your Windows version i.e. 32-bit or 64-bit, and do the following:

For 32 bit Windows:

Select DWORD (32-bit) value.

For 64 bit Windows :

Select QWORD (64-bit) value.

Restart your PC after this so the changes can take place.

The registry change we did adds another 8 seconds of delay to the TDR checker. So if the GPU responds back in 10 seconds, it still works. You may have to change this value to see what exactly works for you.

If it still doesn’t work, you may have to take an aggressive step, and completely turn of TDR. You can do this by changing the “TdrLevel” enter the data value as 0, and then delete the TdrDelay key.

Restart your PC once again.
