I’m using a shelly switch and thermostat (over MQTT) to control a heater. I’m using my own rule to control the switch. It’s working very well, and I’m very happy with it.
I was curious about the HomeKit feature HeatingThresholdTemperature (HomeKit Add-on - System Integrations | openHAB). I understand what it’s intended for, but I don’t understand if it’s meant to be configurable by the user using HomeKit? Or should it change the HomeKit UI to reflect the value.
homekit/home itself has no logic to do anything with thresholds. home app can only be used to configure/set them and the actual device would do some magic, e.g. switch on/off heating on threshold. if device does not support, then thresholds will have no impact.
in home app it looks like this (found on internet)
