Thanks for the feedback @cgrill75!
I haven’t got the indoor sensor so was not able to test. I will add step=0.1 to the indoorTempSetting channel and I guess that will enable you to use 1/10 values within the PaperUI too.
When testing, I used something like:
Setpoint item=regoheatpump_ipRego6xx_ivt_settings_summerDisconnection minValue=10 maxValue=30 step=0.1
within the .sitemap and was able to step between all values, supported by the HP.
Regarding the AdjustHeatCurveAtxxx - I added those based on the mappings available from here but never actually used/tested them - will try to check if they are mapped correctly, but again - it’s error and trial so feedback greatly appreciated
