The rfxtrx platform support sensors that communicate in the frequency range of 433.92 MHz.

First you have to set up your rfxtrx hub. The easiest way to find your sensors is to add this to your configuration.yaml:

sensor: 
 platform: rfxtrx
 automatic_add: True

Then when the sensor emits a signal it will be automatically added:

Here the name is 0a52080000301004d240259 and you can verify that it works from the frontend. Then you should update your configuration to:

sensor:
 platform: rfxtrx
 devices:
    0a52080000301004d240259: 
        name: device_name

If you want to display several data types from one sensor:

sensor: 
 platform: rfxtrx
 devices:
    0a520802060100ff0e0269: 
        name: Bath
        data_type: 
         - Humidity
         - Temperature

Example configuration:

# Example configuration.yaml entry
sensor: 
 platform: rfxtrx
 automatic_add: True
 devices:
   0a52080705020095220269:
     name: Lving
   0a520802060100ff0e0269:
        name: Bath
        data_type: 
         - Humidity
         - Temperature

Configuration variables:

• devices (Optional): A list of devices with their name to use in the frontend.
• automatic_add (Optional): To enable the automatic addition of new lights.
• data_type (Optional): Which data type the sensor should show
