Xiaomi MI Temperature and Humidity Sensors

Tasmota can expose temperature and humidity data from Xiaomi sensors, to expose these sensors you need to configure the names for the sensors.

This is done by setting the MITEMP_NAMES environment variable to comma separated key value pairs of the last 6 digits of the MAC address of the sensors and the desired name.

MITEMP_NAMES="351234=Bedroom,352468=Living Room"

433Mhz temperature sensors

Taspromto can parse data 433Mhz temperature sensors send to MQTT by rtl_433.

rtl_433 needs to be configured to send it's output to the rtl_433[/model] topic, then sensors can be configured by setting the RF_TEMP_NAMES environment variable to comma seperated key value pairs. Where the key is the sensor model, id and channel.
