I have a Sapphire projector screen (SETTS200WSF-AW) that I would like to control from Home Assistant so I can open and close the screen using automations.
The screen has a 12v trigger jack (which my projector lacks), IR receiver and an RS232 interface which is documented as follows
I have a ZigBee network controlled by Home Assistant (ZHA).
Can anyone suggest options for controlling this projector from Home Assistant? Preferably via Zigbee but anything wireless would be ok.
