Lutron Grafik Eye telnet based integration

Development

I have an older Lutron GRX-CI lighting system that I would like to get integrated with HA. It is simple a telnet session where you can send commands to both set and read lighting zones and scenes. Trying to find an existing component that might make the work a little easier.

The Denon mediaplayer platform is using telnet.

@drizzay Andre, just came across this old thread of yours. While HA has a telnet integration, it doesn’t handle login or commands other than on/off. Consequently, for a hospitality client needing to control a large legacy Lutron GRAFIK Eye 4000 system, we were able to use an AppDaemon Home Assistant plug-in to run the Python code that responds to the changes to a HA drop-down helper listing the Lutron scenes, issues the appropriate telnet commands, and reports the status.

There are a lot of small hotels & large restaurants on Lutron GRAFIK Eye, and they may not think that it can be integrated with anything current like Home Assistant, but it can.

I actually cobbled something together that has worked for years. I used shell commands. I recenty asked chatGPT to write code for home assistant for the grapfik eye and it did it better but i haven’t implemented it yet.
lol.
