Integrating a Motorized RF Projector Screen via RFBridge

[ghost]

Hello everyone,

I am looking to integrate my motorized projector screen into Homebridge and would appreciate any guidance or tips from the community. Here is a brief overview of my setup and what I aim to achieve:

Current Setup:
Projector Screen: Motorized, controlled via RF (Radio Frequency) 3-Buttons-Remote (Up - Stop - Down).

Sonoff RFBridge

Homebridge: Running on Sonoff iHost (Docker).

Goals:
Control the Projector Screen: I want to be able to raise and lower the screen using the Home app on my iPhone.
Automation: Integrate the screen control into HomeKit scenes and automations, such as lowering the screen on voice command.

Configuration:
RFBridge: Added Remote Type „2-Buttons“ Sniffed the Down and Up RF-Commands.

iHost: Added the RFBridge and synced the RF-Remote. The Remote is now added to my devices.

Homebridge: Synced my ewelink / iHost devices with the homebridge-ewelink Plugin. This is the generated JSON Entry

In my homebridge devices I now have one device with three seperate Buttons: Up, Stop, Down.

Question:
How can combine these three switches to something displayed as a window-covering, curtain or garage door? The stop command isn`t needed.

I appreciate any help or advice you can provide. Thank you in advance!

Best regards
