WiFi Signal Sensor

The wifi_signal sensor platform allows you to read the signal strength of the currently connected WiFi Access Point.

The sensor value is the “Received signal strength indication” measured in decibel-milliwatts (dBm). These values are always negative and the closer they are to zero, the better the signal is.

# Example configuration entry
  - platform: wifi_signal
    name: "WiFi Signal Sensor"
    update_interval: 60s

Configuration variables:

  • name (Required, string): The name of the WiFi signal sensor.

  • update_interval (Optional, Time): The interval to check the sensor. Defaults to 60s.

  • id (Optional, ID): Manually specify the ID used for code generation.

  • All other options from Sensor.


Signal strength readings are only available when WiFi is in station mode. Readings are not valid if the device is acting as an access point without any station mode connection.
