    Is tado° compatible with my heating system?

    The Smart Thermostat X is suitable for boilers that work with Relay or OpenTherm (which is most of them). You can use it to add convenient and smart room control to your water-based underfloor heating and heat pump. You can find out whether tado° is compatible with your heating system in just a few seconds using our compatibility checker.

    Can I install tado° on my own?

    It’s easy to install it yourself. The app guides you step by step - and is customised to your heating system. You can even install tado° when you’re offline.

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

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

    The Smart Thermostat X is equipped with 3 AAA batteries. tado° reminds you in good time when the battery power is running low and you need to replace the batteries.

    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.

    ¹ Up to 55% more savings is based on internal modelling comparing the use of tado° AI Assist vs the free tado° app. Actual savings depend on household characteristics, usage patterns and external factors.
    ² Actual savings depend on household energy use and may vary. €485 annual savings reflect 22% of the EU average gas heating bill (€2,208) as reported by Eurostat for 2024, based on our user base average. Results may differ.
    ³ Actual savings depend on household energy use and regional factors. CO₂ savings are based on an average EU household gas heating consumption of approximately 20,000 kWh per year and an emission factor of 0.18 kg CO₂/kWh for natural gas combustion, resulting in estimated savings of up to 790 kg CO₂ annually for a 22% reduction. Data based on Eurostat Natural Gas Price Statistics 2024 and European Heat Pump Association reports. Individual results may vary.
