Would anyone be able to point me in the right direction so I can use Home Assistant to control an Extron Crosspoint 300 matrix video switcher over RS-232? All I want to be able to do is switch between different presets I already have programmed into the device.
Here’s the manual for the device, pretty sure chapter 4 is what outlines how to send commands.
Ideally what I’d want this to look like is to have it appear as the media player card in my Home Assistant UI with have each preset listed as a source. If possible I’d like to have it display a different image for each preset, just so it all looks nice.
I’m pretty new to Home Assistant, so I’m always grateful for any help the community can offer.
