HttpGarageDoorController integration

I have used the homebridge plugin homebridge-http-garagedoorcontroller for controlling my gargedoor, I use a D1 Mini with washcroft/HttpGarageDoorController, this software provide a rest api that hombridge plugin communicate with.
I have some success in Hassio with the Command line Switch

But this only make a button in the GUI. I can pulse the opening/closing relay, but not get the states displayed.
Is it possible to make a symbol with a button to open close the garage door, and also display the current state in the same display?
Hope somebody could guide me on how to start solving this issue.

The api for the d1 mini software is described here:

The rest api has endpoints for all those functions, so keep adding sensors and switches, but you would be far better off using this

Thank you!
