Hi,

Im trying to control my Techneco Elga heatpump. However, it does not seem to accept TT, TC, TS or CS commands as there are immidiately overwritten by the thermostat. I've tried several thermostats including the Honeywell modulation touch, honeywell chronotherm modulation 3 and the Remeha isense. I've attached the logs below. Does anyone have an idea what might be going wrong here? Thanks!!

The TT and TC commands affect the thermostat, not the boiler/heat pump. They should work with all thermostats you mentioned.
The TS command configures an attached temperature sensor. I'm unsure how that is related to your situation.
The log you provided is not a normal OTGW log. It looks like it may be a debug log of the Wemos firmware. I'm not very familiar with this type of log, so I don't exactly know how to interpret it. I don't see a response from the PIC to the TT=22.0 command. I would expect that. Does any command work?
When using the firmware of rvdbreemen on the Wemos, you can connect OTmonitor to port 25238 and get a log that I can work with.
