Hi everyone, I have some older version Heltun Heating Thermostat (HE-ZW-THERM-FL2 with 500 chip) currently running with a Fibaro HC2, but want to move them over to my new HP23 setup. I have problems including them to my Homey - and it seems that the Heltun app only supports the newer 700 series thermostats from Heltun (HE-HT01).
Has anyone been able to use the older 500 series devices from Heltun with Homey? If yes; than guidance would be highly appreciated
