pimatic-serial-ivisions
Pimatic Plugin that supports sending commands to iVisisons projector screens and projector lifts over the RS485 interface. I use a cheap USB RS485 controler from eBay to talk to the projector screen.
The iVisions projector screen seems to be a rebranded screen as I found it only to be available in the webshop where I bought is. Some Googling around proved me right, as the protocol is used in more devices.
This are the protocol details: 2400 baud 8N1 up command : 0xFF 0xAA 0xEE 0xEE 0xDD down command: 0xFF 0xAA 0xEE 0xEE 0xEE stop command: 0xFF 0xAA 0xEE 0xEE 0xCC
Known to work: iVisions Electro M Series
Not tested but use te same protcol according to the documentation: iVisions Electro L/XL/Pro/HD Series iVisions PL Series beamer lift Elite Screens XY Screens
Please let me know if your projector screen is also supported by this plugin so I can improve the overview of supportd devices.
