· Die Bibliotheken für den MH-Z19 Sensor kennt Home Assistant schon und sie stehen ohne weitere Installation zur Verfügung. Die Sensor-Plattform wird ab Zeile 39 gesetzt. Mit on_value_range ab Zeile 44, können nun die LEDs angesteuert werden.
· CO2 sensors need to be calibrated now and then, the default for MH-Z19B being Automatic Baseline Calibration (ABC) to lowest measured values every now and then (day?), which would be assigned the ballpark outside CO2 figure of 400 ppm. This is far from accurate and cannot be used to monitor rise of CO2 in the atmosphere, but is tolerable for inside air quality measurement, where most …
· there is a bug with MQTT, Home Assistant, Home Assistant MQTT Discovery and the MH-Z19B ( link ). It can be seen at the log files: The name of the json parameter is MHZ19, but the device name is MHZ19 B (ending with B!). This results to Home Assistant not finding the correct json element which was announced and to 0 values.
