Wi-Fi problems can leave your Tado thermostat unresponsive, even when your app suggests everything is fine. If “No remote access” appears or your devices show offline, here’s how to identify and fix the issue.
To begin, determine whether it is the thermostat or the Internet Bridge that has lost connection. If everything appears offline in the Tado app, the bridge is likely disconnected from your home network. If just one thermostat is offline, it may have lost signal or pairing.
The Internet Bridge connects via Ethernet rather than Wi-Fi. It uses a low-frequency 868 MHz signal to communicate with your thermostats. This signal can be disrupted by thick walls or interference from nearby appliances. Place the bridge in a central, open spot using a longer Ethernet cable if necessary. Avoid cupboards or enclosed spaces, as these can block the signal.
The message “No remote access” indicates that the Internet Bridge has lost contact with Tado’s cloud servers. While schedules will still run locally, you cannot control devices remotely. If your home internet is working, restart the bridge by unplugging and reconnecting it.
You should only reset the thermostat after trying other options. First, restart the router and the bridge, move the bridge closer to the thermostat, and check for any firmware updates. If the thermostat still does not respond, follow Tado’s instructions to re-pair the device.
Firmware updates are automatic, but devices that have been offline for some time may miss them. Reconnecting to the internet should trigger any pending updates. You can check the firmware version under Settings > Rooms & Devices in the Tado app.
Most thermostat Wi-Fi issues can be solved in minutes by improving the bridge location, restarting the network, or checking that the thermostat is still paired correctly.
Tado works with most boilers in the UK, including both combi and system models. However, some systems require specific accessories or settings to function correctly.
Combi boilers heat water on demand and usually support basic relay control. System boilers use hot water cylinders and often require an Extension Kit for full compatibility. You should use Tado’s Compatibility Checker online to confirm your boiler’s requirements before purchasing.
Tado can use OpenTherm for more efficient control, but only if your boiler supports this standard. If not, standard on and off relay control will still provide reliable functionality. Check your boiler manual or speak with an installer to determine support.
To check compatibility, visit the Tado website and enter your boiler’s make and model into the Compatibility Checker. It will show you which kit is required for your system.
You should choose a wired setup if you have existing thermostat cabling. Choose a wireless setup if you need to install the thermostat in a different location or if there is no wiring in place. Wireless systems use the Tado Smart Thermostat with either a Wireless Receiver or Extension Kit.
The Extension Kit is required if you want to control hot water on system boilers, use a wireless installation, or if your home does not have an existing wall thermostat.
Always confirm compatibility using the boiler compatibility guide to avoid unnecessary delays or purchasing the wrong kit.
Many users can install Tado themselves, especially for straightforward wired replacements. However, more complex systems often benefit from professional installation to ensure everything is set up safely and correctly.
DIY installations typically take between 30 and 60 minutes. A professional installation will usually cost around £100 to £150, depending on complexity and location.
Wired systems replace existing thermostats using wall cables. Wireless setups require placing a receiver near the boiler and pairing it with the thermostat. While wired systems are quicker to install for direct replacements, wireless systems provide more flexibility in thermostat placement.
You should call a professional such as RightAir if the wiring is unclear or unlabelled, if you are adding hot water control, if you need the Extension Kit, or if your system includes zoning or underfloor heating.
In the UK, replacing a wall thermostat is legal and within the scope of DIY. However, any work involving internal wiring inside a boiler must be carried out by a Gas Safe registered engineer.
You can install the system yourself if you are replacing a thermostat in the same spot, if the wires are clearly marked, and if there is no need to access the inside of the boiler. You should call RightAir if you are installing a receiver at the boiler, managing hot water, or if you feel unsure about safety or wiring.
If your setup is straightforward and safe, you can complete the installation yourself. For more advanced systems, it is better to hire a qualified installer.
Pro Tip: Place the Internet Bridge in a central, open location away from metal or routers to avoid signal issues.
Wired and wireless systems both offer smart heating control, but they are suited to different types of homes and installation needs.
Wired setups are fixed in one location, use existing wall wiring, and draw power from the boiler circuit. They are ideal if you are replacing a thermostat in its current position.
Wireless setups are battery-operated and can be moved around the home. They communicate via a receiver placed near the boiler and are ideal if you want to install the thermostat in a different room or do not have existing wiring.
If your home has thermostat cabling in place, you should consider a wired setup. If not, or if you want flexible placement, a wireless setup is the better choice. If you also want to control hot water, then you will need the Extension Kit.
Choosing the right setup depends on your wiring, where you want the thermostat, and whether your system includes hot water control.
Tado continues to operate without internet access, but only in a limited capacity. This is part of its offline fallback mode, which allows basic heating control even if the connection is lost.
While offline, Tado thermostats will continue to follow their scheduled heating routines. You can also make manual adjustments directly on the thermostat itself. However, you will lose access to app control, remote adjustments, geofencing, and automated weather adaptations.
Although your heating will still function, full smart thermostat features will only return once internet connectivity is restored.
Yes, Tado can control hot water if you have a system boiler and install the Extension Kit. This setup enables smart control of hot water schedules and remote adjustments.
With Tado’s hot water control, you can create a schedule that suits your daily routine, switch hot water on or off from your phone, and reduce energy use when no one is at home. This is especially helpful when paired with geofencing.
Using the Smart Schedule in the app, you can divide your day into time blocks such as 6:30 to 8:00 in the morning, 12:00 to 1:00 midday, and 5:00 to 9:00 in the evening. You can override schedules or pause heating when the home is unoccupied.
By installing the Extension Kit, Tado becomes your full smart control system for both heating and hot water.
Get your Tado system set up by a certified professional. Avoid guesswork and keep your warranty intact.
If your boiler is not turning on when expected, the thermostat may not be calling for heat. This could be due to a number of typical issues.
The room temperature might already be above the set target, the thermostat might have lost its signal, or the schedule could be in an energy-saving mode such as Away or Eco. You might also be dealing with a thermostat pairing issue or signal dropout between devices.
To resolve this, try manually increasing the temperature and see if the boiler responds. If it does not, restart the Internet Bridge and check device status within the app.
Most common smart thermostat problems like this can be resolved quickly with basic checks.
Tado can be used with water-based underfloor heating systems, but it is not compatible with electric systems.
For integration with hydronic underfloor heating, you will need a wired thermostat for each zone, a compatible wiring centre or manifold, and potentially additional thermostats depending on how many areas you need to manage.
These systems typically run at lower flow temperatures, so zoning becomes essential. You should consider multiple thermostats and use Tado to manage each room individually. For larger installations, a smart underfloor heating controller alongside Tado can improve efficiency.
When configured correctly, Tado offers reliable and intelligent control for hydronic underfloor systems.
Pro Tip: Always check your boiler model against Tado’s official tool before purchasing any smart thermostat.
Tado firmware updates are fully automatic when your devices are connected to the internet. You do not need to trigger anything manually.
