The multi-zone evohome controller controls the time and temperature of up to 12 heating zones plus a domestic hot water supply if required. Each zone has independent time and temperature control. Ok, so I've now tried removing the HR92 that's bound to the guest bed zone into a location that's only a few feet away from the controller with direct line of sight. Again, same issue. To rule out an issue with the controller, I created a new 'test' zone on the controller and bound it with the HR92. However, this hasn't cured the comms fault.

Managed to get the correct thermostat modes to show app in the modes list in the new app presentation Used just as a Connected Thermostat, the evohome Wi-Fi Connected Controller acts as an intelligent programmable thermostat and the pre-bound BDR91 wireless relay box creates the switched live demand for your heating system, meaning it is compatible with every 230v heating system (S Plan, Y Plan or Combi Boiler Systems) and also systems using low voltage switching. optimisation features calculates heat-up and cool-down time allowing programming of actual heating needs

None of this makes any sense, as I swapped the guest bed HR92 with another room in my initial testing and the fault still stayed with that room, which suggested a central controller or RF fault. I can now rule out an RF fault as I'm seeing the error when the HR92 is just feet from the controller. A controller fault with that particular zone is now looking less and less likely, as I'm still seeing a comms error even after creating a new zone. Managed to get the modes to work with the new app’s presentation. Some list items appear weird but this is a Smartthings issue Functioning as a Connected Thermostat, the Evohome Wi-Fi Connected Controller serves as an intelligent programmable thermostat. Moreover, it is compatible with every 230v heating system, including S Plan, Y Plan, or Combi Boiler and Heat Pump Systems and also systems using extra low voltage switching. V3.2 Replaced the hot water mode with the new custom thermostat mode to fix the wording. Also removed the deprecated refresh capability from both the zone and hot water thermostats to avoid them from showing up in the automation options.evohome allows the installation of multiple temperature sensing devices around the property without altering existing pipework, disrupting décor or damaging fixtures and fittings. V3.1 The Alexa issue where it was not possible to set the temperature from the app or voice has now been resolved. Also as an added bonus, the Thermostat Modes now display the modes correctly.
