I have an IR controllable HDMI switch box, it’s good, but the manufacturer seems to have stopped making it. I’d like to add the remote control to my HASS dashboard, and do away with the annoying clicky-bubble-button flimsy zapper that came with it. Bonus points: Discover undocumented additional discrete codes to switch to each HDMI channel, as the remote only has buttons for switch left/right.
The HDMI box itself is a ‘Fosmon 3x1 Optical Audio Switch’ and it looks like this:
The IR unit is completely unbranded, and looks like this:
Using my ESPEasy board with IRRX sensor, I can read the output from each button, easy. I can even fire them back out of the ESP with an IRTX setup. Job done, right?!
Not quite, I’d really love to be able to specify which input to jump to, for two reasons:
1: It’s annoying to have to hit multiple times to cycle inputs.
2: The box auto-switches to the active port when it picks up a new HDMI signal coming from that port, so It’s hard to do an ‘optimistic’ tracking of which input is active without seeing the box itself (buried in my garage).
Of course, after spending a longer time than I’d care to admit Googling, I was unable to find either codes for the box, or any details on the remote. So next step I guess is to pick a range of numbers, close to the ones I already have for the 10 buttons on the remote, and fire them at the switcher from ESP until something happens.
Has anyone done this and can recommend a way to take some of the labor-intensive guesswork out of it please? I appreciate there may well be no discrete codes available, but I’d like to at least be able to say I’m sure of that. Without a good starting point, I’m looking at some of the better supported Fosmon boxes (like the HD1996) to see if the codes are the same.
