I'm messing arround with all the stuff like learning by doing, also with the Rules - scripting thing... There I have the idea to use a Sonoff (Simple, Wallplug, ....) as a autark temperatute switch...
I like to connect i.e. a DS18B20 and then scripft a Rule that controll it. But what I don't know is how I set a variable that I can change from outside, in this configuration the temperatur and hysteresis. "from outside" I think about FHEM via FHEM-HTTP or maybe MQTT.
What I like to see in FHEM is: Switch-Status (ON/OFF), actual temperature, hysteresis, switchpoint-temperature (i.e. ON / 16,5°C / 1,5k / 18,0°C)
What I like to controll / change from FHEM is: Switch-Status (ON/OFF), hysteresis, switchpoint-temperature
Hopefull that my english isn't so ugly that you can follow ...
