Hello,

I am using Homey Heating Scheduler version 2.0.7 on a Homey Pro 2026.

My virtual thermostat, “Plan Temperatuur Schedule”, is linked to two Aqara W600 thermostats:

- Kitchen: measured temperature 18.0 °C

- Bay window: measured temperature 18.5 °C

Both temperature readings arrive correctly in Heating Scheduler, but the virtual thermostat displays approximately 12.2 °C instead of the expected average of 18.25 °C.

Changing the virtual thermostat’s target temperature also results in a “Timeout after 10000ms” error.

I have restarted the app several times without success. The problem persists.

Could you help determine why the virtual thermostat is not updating or calculating its measured temperature correctly?

Kind regards
