Hey, I want to control my projector. I could obviously just use a Boradlink RM mini or so to use the IR interface. But that way has some drawbacks as I need a good positioning, which also means a visible positioning of the transmitter.
Therefore I had a look at the back and found a RS232 interface, which can be used at least for turning on and off (maybe even more, but that would be everything I’m looking for at the beginning). Now I just need a connection from my HASS to that serial port. I was wondering if an arduino could the best solution? Do you know any similarly cheap and maybe easier all-in-one solution for a remote serial box?
If arduino was the best way; what would I need? Would it be anough to just add something like this?
As you might have recognized I am not familiar with Arduino so far; though I’m quite comfortable with running HASS on docker ony an Ubuntu based server. I also have an odroid running, but both are based in the basement, far away from the projector.
any help appreciated!
