Robot vacuum automatic door system

I found this cool project: [HIDDEN INSTAL] Robot Vacuum Automatic Door System - #49 by smowk - Share your Projects! - Home Assistant Community

I think the mechanical part I would be able to do myself, but does anyone have any idea how one would go around getting something like this integrated in Homey?

It looks like they use an ESP8266
This works @ Homey with the ESPhome app.
