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 Thread border router in your home, you won’t need a 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.

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+.

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. The entire network only requires one Thread border router, regardless of the devices you have and the manufacturers they’re from.

Tado X Thermostat and Bridge

I have used the X Series Products since February now (I was Part of the Early Access programm) and i had no issues whatsoever. Setting it up took me maybe a minute as it pretty much does it all itself. Same with the Bridge.

I also really like that it uses USB C to charge its internal battery. No more having to buy batteries all the time.
I am overall extremely happy with it as I had no issues with it at all (unlike the company i had a smart thermostat from before switching to tado)
I can overall only recommend it. And I hope you guys can enjoy it aswell!
