Heatit Z-wave app (v2.7.1)

@naitsirk thanks for the detailed feedback.
I do recognize that the device updates the display with some delay; after confirming the setpoint.
This has always been the case with the Heatit thermostats.

For the switch on behavior; could you repeat the steps, after a fresh restart of Homey (30 minutes to allow the device to initialize), and please use for each step (from Homey or on the thermostat) a unique setpoint value. With sufficient time in between to allow the thermostat to switch on.

After completing these steps; can you send me:

  1. The transcript of the steps used with the set points used
  2. A screenshot of the device settings; developer.athom.com > devices
  3. A diagnostics report from the app; Homey app > settings > apps > Heatit > send diagnostics report (with reference to your username)

Based on the latter, in combination with the first I can check the behavior (confirmations) of the device.
If all the set points as send by Homey are confirmed by the thermostat, it would point to internal Logic, for which the device settings are important
