I'm working on a project that needs the ability to control an HDMI switch programmatically. There are going to be a lot of these boxes so price of the components used is very important.

I've experimented with automatic HDMI switches but I can't seem to get the level of control I need. I'm thinking about using a switch with a remote control but hardwire it to the GPIO.

The idea is I can hardwire from the GPIO to the IR socket and simulate the and be able to make the switch change inputs. I'm looking at using this specific HDMI switch:

Is this possible?

thanks

Yes, it is possible.

You will need to connect an IR LED and some circuitry to switch it from a Pi GPIO (an IR LED needs more power than can be supplied by a PI GPIO).

If you search for IR blaster and Raspberry Pi you may find some ready made products and/or designs for ones you can build yourself.

Once you have this hardware you will be able to send the IR commands using software on the Pi.

You should be able to find lots of similar projects if you search.
