Force Calibration via MQTT #7

Open z8i opened 3 years ago

z8i commented 3 years ago

I like to start the forced Calibration via MQTT, so i added a topic "mqtt_prefix/forceCal", which the ESP will subscribe to. If this is set to "1", the forced calibration starts.

I included two "double-blinks", one for a successful calibration and one for "Sensor not ready".
