Hi Bart,
I have implemented your modified firmware of viewtopic.php?f=75&t=11419 in my 2-zone setup (ATAG i36EC boiler, Honeywell Round Connected thermostat) and it appears to work nicely! (So the setting of the controlsetpoint a with a thermostat-controlled relay connected to the GPIO B pin, in my case.)
Have you eventually managed to apply the modification to the latest 4.2.5. firmware as well?
Reason I ask this is that the PR=I command is not suported in 4.2.4. It would be nice to be able to monitor the state of pin with the setback input. Actually, Domoticz has native support for this already, but for 4.2.4 it gives PR=BV (bad value).
Or is the code for the PR=I command available somewhere else? I may try to include it myself, although I am hesitant to do this as I have no experience in modifying/compiling Assembly.
Tom
