Did a little more work last night and got some good results.
On OpenHAB the binding uses this configuration:
11:command=THERMOSTAT_SETPOINT,setpoint_type=1,setpoint_scale=1
This will return and use Fahrenheit for the SetPoint. Changing the setpoint_scale to zero as below I can adjust the SetPoint within OpenHAB and see it appear on the Thermostat when it wakes up and receives the command.
11:command=THERMOSTAT_SETPOINT,setpoint_type=1,setpoint_scale=0
Any ideas on what i can adjust in HG to make it work?
Thanks,
Garry
