  • Thermostat chaning setpoint every 5 seconds

    A couple of days ago one of my thermostats is going nuts. The setpoint is changing every 5 seconds from 18 to 22. No input from me, or any event (I have checked by disbling all events which change the setpoint). When I take the batteries out of the thermostat, I still see the setpoint changing in the log (and the device). So it cannot be the thermostat either. Next I tried changing the schedule. Bingo. No more changes. I have deleted and rewritten the schedule in question. First of all all was good, now its starting again. I have 4 other themostats, all the same make, none of them misbehave. The one in question now has worked fine for 2 or 3 months since installation. I am not entirely sure when this problem started, I only noticed it 2 days ago.

    This is an example of my log:

    This is the schedule in question (Lounge), and the thermostat in question is the Lounge TRV. The other thermostats on the screenshot are the same model, but work without any issues.

    I found the issue. If I sett the sleep time before midnight, its fine. If I set it to after midnight, it goes crazy.
