7. Add GPIO device

Introduction

GPIO devices are unique in that they don't require any set-up on the ESP unit. They also don't take up any of the 12 available device slots of the unit. You don't even have to set up Homey as a controller in the ESP unit to get this working! The unit does have to be known to Homey. You can do this by setting it up as a controller or by adding a "Unit" device to Homey.

Step-by-step

We're going to add a simple digital output device. You don't have to actually have to have anything connected to the chosen GPIO port, you can just check it's status on the "Pin state buffer" page which you can find in the Tools tab.

• Add a new device to Homey
• Select "ESP Easy"
• Select "GPIO Digital Output"
• If you have set up Homey as controller or added a "Unit" device, you can select the unit from a dropdown list
• Choose the GPIO port you want to use
  • Note: Only use the ports with a warning sign in front if you know what you're doing!
  • Check out this page for more information about which GPIO port to use
• Select the Homey device capability you want to use
  • This impacts the way Homey shows your device and the ways you can interact with it
  • Just remove the device and re-add it if you want to try different options
• Click next to add the device
