Warning: tado° X devices are not compatible with earlier product lines.
tado° X and V3+ use different technology platforms, despite offering similar functionalities. tado° X is not compatible with earlier tado° devices and they can’t be used together on the same account.
What is the difference between tado° X and earlier products?
- tado° X and V3+ use different technology platforms, despite offering similar functionalities. 
- tado° X uses the Thread protocol to communicate between devices. 
- using Thread creates a mesh network that allows multiple tado° X Bridges and Thread border routers to be added, extending the range in large spaces. Prior tado° product lines only allowed one Internet Bridge per home. 
- The Smart Thermostat X, Wireless Temperature Sensor X, and Smart Radiator Thermostat X are Matter-enabled and can communicate with non-tado° devices that are also Matter-enabled. 
- V3+ tado° products provide very reliable heating control and are compatible with a wide variety of heating setups, including boilers from many different manufacturers. 
- Compared to the V3+ range, tado° X products are compatible with a smaller array of modulating boilers. 
I already have tado° products. Can I add a tado° X device?
tado° X devices can’t be added to setups that use V3+ and prior. tado° X devices can’t communicate with earlier tado° products, as they use different technology platforms and communication standards.
How can I switch to tado° X?
There are a few considerations to bear in mind when replacing your existing tado° setup with a set of tado° X products.
- Before installing a tado° X setup, you will need to create a new Home in the tado° app. - To use the same email address, delete your V3+ Home, then create a tado° X Home. 
- To keep your V3+ Home, create a new tado° account using a different email address. 
 
- There is currently no copy-paste function to transfer settings like Smart Schedules, Energy IQ, and room data from your V3+ account to your new one. You will need to manually re-enter these details. 
- Register and install your tado° X devices starting with one of the following: - a tado° Bridge X (included in our starter kits) 
- a supported Thread border router from another provider

Is my heating system compatible with tado° X?
- tado° X offers high compatibility with heat pumps, thanks to the Heat Pump Optimizer X. 
- tado° X works with most boilers. The only requirement for tado° to work with your boiler is that it communicates in a language that tado° can understand and process. 
- One of the most common ways in which thermostats communicate with boilers is through simple relay (on/off) connections. The Smart Thermostat X is compatible with almost all boilers that support relay connections and modulating Opentherm connections. Compared to the V3+ range, tado° X products are compatible with a smaller array of modulating boilers. 
If your Wired Smart Thermostat V3+ controls a non-Opentherm modulating boiler, tado° X may not be compatible with your heating system, even if you have earlier tado° products. Please contact tado° support to confirm compatibility. Tap the round orange icon to open a chat.
