I’ve had a Tado° system for a few years now; initially I started with a single thermostat and extension kit in a previous house. When we moved, our new house had multi zone heating with separate thermostats; one for the lounge and one for the rest of the house. I added a second thermostat for the lounge and then soon after that 6 radiator valves. This setup allows me to automatically set each room for optimal comfort. Currently, I have my home setup so:

The nursery is set to a maximum of 18°, and if required will heat for an hour before my daughter (should) go to bed.

The bedroom is set to a default of 18° over night and during the winter will call for heat as required.

The rear bedrooms are off by default as the majority of the time are empty.

The kitchen only comes on for 30 mins in the morning if required.

The dining room is also south facing so doesn’t need much in the way of heat.

The great thing about the valves is that you can control them without an app using a single input, just like you would with a ‘dumb’ valve. Turning the top ring will either increase or decrease the temperature, and if required ‘call for heat’ from the boiler. You can also preset each valve to perform an action when manually controlled:

Until turned off again

For a set duration

Until the next automatic mode change (based on the smart schedule)

Setup

HomeKit enabled bridge (https://www.smarte-thermostate.de)

Upgrading the new bridge was trivial and took about 40 minutes in total. The process was to:

Add the new device via the Tado° app by scanning a QR code

Swap the bridges over

Wait for the devices to connect to the new bridge

Assign each device to a room within HomeKit

The only slight annoyance was that the default name that was assigned to each device was the serial number, and not the zone it was assigned to. There’s probably a good reason for this, but it made assigning each device to a HomeKit room harder than required. This is probably only an issue if you’ve got quite a few devices. I logged in to the web app, navigated to the devices settings and used that to look up each serial number. You could also use the ‘identify’ feature depending on how many devices you have setup.

I also had to create a new ‘House’ room to assign the main ‘Home’ thermostat. This works quite nicely as I can ask Siri what the temperature in the House is.
