To link Hubitat and Meross garage door opener do the following:
- In Hubitat add a Virtual Garage Door Controller.
- Add the IFTTT intergration app to Hubitat and allow the Virtual Garage Door Controller to be shared.
- Create/Login to IFTTT and add Hubitat and Meross to your account.
- In IFTTT click on your user (in the top right) and click create.
- For the "This" part search for Hubitat and use "Device opens" then select your virtual garage door.
- For the "Then" part search for Meross and select your garage door opener.
- Repeat the steps for closing the garage door but use "Device closes" instead.
