When the time comes, (22:00) it writes to the thermostat history “thermostat program sent setHeatingSetpoint command to Heater” but the temperature setting did not change

Check out my post above about lost commands.

[RELEASE] 5-2 Day Programmable Thermostat Scheduler (Weekday, Weekend) with Remote Temperature Sensor for each Schedule

You’re welcome. What you’re describing sounds like a typical mesh issue. Is the mesh is weak it can “lose” commands so it appears that sometimes it works and other it doesn’t. The solution is to add a repeater close to your device. It a very common issue especially with locks and thermostats. Here is a topic explaining the issue and why repeaters are needed even if the hub is close to your devices. (It’s for locks by applies to most beaming and sleepy devices)

Also try wiring your thermostat with the C-Wire which helps it not “lose” commands (it switches from beaming mode to active listening/repeating mode). After adding the C-Wire your thermostat you will need to be excluded and re paired with the hub for the changes to take affect.

EDIT: Maddie is working with you on this, looks like your hub has a wrong/different timezone assigned to it which causing the app to fire at time different from your local time.
