Besides the Internet Bridge, you can have a maximum of 25 heating devices in your tado° Home.
So, in theory, if you have one tado° heating device per room, you can have up to 25 heating rooms in your Home.
But heating setups are usually more complex than that. So, the number of rooms you can have in your tado° Home depends on your heating system and how you wish to set up your tado° devices to control your heating.
For central heating systems
If tado° directly controls your central heating system, you can set up your tado° devices to communicate with each other to maximise comfort. Devices in up to 10 of your tado° rooms can be set up to communicate with the tado° device that controls your central heating. This means that when any of the devices in these rooms call for heat, tado° will turn the heating system on to provide heat to these rooms.
This setup is recommended if all these rooms are in the same heating zone. For example, if your Smart Thermostat or Extension Kit controls a boiler that also supplies heat to these rooms.
You can also have more than 10 rooms in your tado° Home in this setup. However, the devices in these additional rooms cannot be set up to communicate with the central tado° device. This means that these rooms will get heat when one or more of the 10 rooms that communicate with the central tado° device call for heat.
If you wish to add more than 10 rooms in such setups, our Technical Support team will be happy to assist you.
For cooling systems
You can have up to 25 Smart AC Controls in your tado° Home. So, in addition to the rooms for heating, you can have a maximum of 25 rooms for cooling in your tado° Home.
