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.

Here you can find a list of Thread Border Routers that work in place of the tado° Bridge X.

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

Will I have to replace the batteries?

The Smart Radiator Thermostat X is equipped with a rechargeable battery. This means you don't need to replace any batteries. Simply remove the rechargeable battery and charge it with a USB-C cable. This only takes about 2 hours and only needs to be done about once a year.

You plug the Bridge X into a socket, which means it doesn’t need 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. The entire network only requires one Thread border router, regardless of the devices you have and the manufacturers they’re from.
