Is tado° compatible with my heating system?

You can find out whether the tado° Smart Radiator Thermostat X is compatible with your radiators in just a few seconds using our compatibility checker. In general, tado° is compatible with almost all manufacturers. Each pack contains six adapters for a variety of valve types.

Can I install tado° on my own?

You can install it yourself in just a few minutes. The app guides you step by step, and is customised to your radiator model. No risk of water leaks. And even if you’re offline, you can still install tado°.

I'm buying tado° for the first time. Do I need a Bridge X?

If you already have a compatible Thread Border Router in your home, you won’t need an additional Bridge X. Otherwise, you can either order a separate one here, or buy it as part of a Starter Kit with your Smart Radiator Thermostat X. Please note that the Internet Bridge from the V3+ series is not compatible with tado° X.

Here you can find a list of Thread Border routers that can be used in place of the tado° Bridge X.

I already have tado° V3+ with an Internet Bridge. Is this compatible with tado° X?

If you already have tado° V3+ devices in your home, simply expand them as before with the V3+ Add-ons. The Bridge X and all tado° X products are not compatible with tado° V3+.

Can I control tado° using my smart assistant?

You can control all tado° devices easily using Alexa, Google Assistant and Apple Home.

Can I install tado° in my bathroom?

Yes, tado° X is suitable for installation in wet areas.

Can I return tado°?

Yes, you have a 30-day right of return following your purchase.

Will I have to replace the batteries?

No. The Smart Radiator Thermostat X is equipped with a rechargeable battery pack. Simply remove it and charge it with a USB-C cable. This only takes about 2 hours and only needs to be done about once a year.

What happens if I’m offline?

You can still install tado° if you’re offline. What’s more, Smart Schedules will continue to run even when you’re not connected to the internet because they are saved locally on the device.

What's Matter?

Matter ensures a simplified connection between tado° and your smart home, regardless of which products or brands you’re using. Matter-enabled devices will work together reliably and securely now and moving forward into the future.

What's Thread?

Thread technology was developed to make networking smart home devices easier: Thread-enabled devices form their own, robust network so that they communicate with each other.

What does "Refurbished" mean?

Our refurbished products have been previously used and returned by customers, so they may show signs of wear. However, our team of experts has thoroughly tested them to ensure full functionality.
