GPIO Switch
===========
The ``gpio`` switch platform allows you to use any pin on your node as a
switch. You can for example hook up a relay to a GPIO pin and use it
through this platform.

# Example configuration entry
switch:
- platform: gpio
pin: 25
name: "Living Room Dehumidifier"
Configuration variables:
------------------------
- **pin** (**Required**, :ref:`Pin Schema <config-pin_schema>`): The
GPIO pin to use for the switch.
- **name** (**Required**, string): The name for the switch.
- **power_on_value** (*Optional*, boolean): The state this switch should be initialized with on boot.
Please note that certain pins can have pull-up/down resistors that activate/deactivate a pin before
esphomelib can initialize them. Please check with a multimeter and use another pin if necessary.
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
- All other options from :ref:`Switch <config-switch>` and :ref:`MQTT Component <config-mqtt-component>`.
