GPIO Switch =========== .. seo:: :description: Instructions for setting up GPIO pin switches in esphomelib that control GPIO outputs. :image: pin.png 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. .. figure:: images/gpio-ui.png :align: center :width: 80.0% .. code-block:: yaml # Example configuration entry switch: - platform: gpio pin: 25 name: "Living Room Dehumidifier" Configuration variables: ------------------------ - **pin** (**Required**, :ref:`Pin Schema `): The GPIO pin to use for the switch. - **name** (**Required**, string): The name for the switch. - **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation. - All other options from :ref:`Switch ` and :ref:`MQTT Component `. .. note:: esphomelib will attempt to restore the state of the switch on boot-up and write the value very early in the boot process. 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.
