Domoticz

Hi central heating has thermostat in living room.
We are having so 24/7 same temp 20C.
Thermostat connected via OTGW with heatpump.
Just a day out of the blue temp setting weng down to 17C.

Any thoughts?

The problem here is was is it Domoticz setting the lower temp or was Domoticz receiving the lower temp from OTGW. In Domoticz sometimes the responsible origin is listed in the setpoint log (user name, hardware name , lua or timer). Sometimes the field is empty....

Edit I see now there is no switch log anymore for setpoint....
