Hello!
I cannot get the Homematic IP thermostat eTRV to work with the Homematic Binding.
There is always an error “A blank string is not a valid number” in the log as soon as the thing is added und all values are empty.
I guess the binding cannot get the values because some are not filled as expected.
I am using CCU2 and the latest openHAB-Snapshot.
As a workaround i am using the HMTL-Binding to retrieve the temperature but of course this is not a solution.
Any advice?
Thank you.
