A really basic question, but our current analogue thermostat is wired to the wall. Does that mean I need to buy a wired Tado? Or can I repleace with a wireless version?
I had a programmer and wired thermostat. I've been too lazy to remove the thermostat (it will leave a hole in the wall) so have just turned that up to 30. The programmer was replaced with the Wireless Receiver, wired to the boiler. The starter kit I bought included a wireless thermostat which I didn't intend to use, as I have TRVs, but it turns out that a thermostat is required to switch the hot water on via the receiver.
I have the UK version as that has relays which is what I need. I think it can be switched into a mode where it will talk to a fancy modulating heat source but I've never tried that.

and many TRVs. I bought basic. https://www.screwfix.com/p/tado-basic-white-smart-radiator-thermostat/861kg
I have Tado. It's mostly been trouble free. I had a problem with one TRV not turning off which after I opened a support ticket and went through the motions they sent a replacement.
I have lots of TRVs so lots of batteries to change every 9-12 months but it gives me the control I want, for example the guest room is currently set to very low but I can turn it up when someone is staying.
I'm using the WebKit HomeAssistant integration to control some things. That is local to my LAN, everything else needs the Tado cloud. I mostly use the app though as it is easier.
I believe fancy boilers and heat pumps can be communicated with using some sort of serial bus rather than relays. There are terminals on the Tado for that but I have no experience as my boiler is about 40 years old.
