Sadly after many weeks of trying I have given up trying to add TadoX thermostatic radiator valves to HA. I have tried every possible combination of TadoX Bridges, Apple TV, Google Home Thread Routers and nothing works.
I add all 11 devices to Tado app, no problem (with TadoX bridges turned on)
I try to add them to HA, ‘Device not found’
I add all 11 devices to Apple Home, no problem (with TadoX bridges turned on)
I try to add to HA ‘Device not found’
I try again using the Apple thread code with the TadoX bridges turned off.
I try to add to HA ‘Device not found’
But after turning off the TadoX bridges the TadoX app looses connection to some of the devices and so does Apple Home.
So I am resigned to not being able to add these devices to HA. I will have to use both HA and Apple Home rather than one interface.
Maybe an upgrade to the Matter/Thread config in HA will resolve this? Maybe a dedicated config for TadoX devices will appear. But for now this is the way it is.
I will keep a watchful eye on any upgrades that may resolve this hopefully.
