WiFi Signal Sensor
==================
The ``wifi_signal`` sensor platform allows you to read the signal
strength of the currently connected :doc:`WiFi Access Point </esphomeyaml/components/wifi>`.
The sensor value is the `"Received signal strength indication" <https://en.wikipedia.org/wiki/Received_signal_strength_indication>`__
measured in decibels. These values are always negative and the closer they are to zero, the better the signal is.

# Example configuration entry
sensor:
- platform: wifi_signal
name: "WiFi Signal Sensor"
update_interval: 15s
Configuration variables:
------------------------
- **name** (**Required**, string): The name of the hall effect sensor.
- **update_interval** (*Optional*, :ref:`config-time`): The interval
to check the sensor. Defaults to ``15s``. See :ref:`sensor-default_filter`.
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
- All other options from :ref:`Sensor <config-sensor>` and :ref:`MQTT Component <config-mqtt-component>`.
.. warning::
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.
