I am using Tado for a while now, but I notice after a while the app can’t control the radiator thermostats anymore. It looks like it’s working and doesn’t show an error, but the radiator thermostat doesn’t respond at all. When I restart the app in Homey, it works fine again for a while.
I have no issues using the Tado app directly, so it seems to be something related to Homey. The fact that restarting the app resolves it, also proves this.
