 ## 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.
+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.
 
 ```dotenv
 MITEMP_NAMES="351234=Bedroom,352468=Living Room"

+Taspromto can parse data 433Mhz temperature sensors send to MQTT by [`rtl_433`](https://github.com/merbanan/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.
