I spent long than I would have liked setting up a touch of automation for our home media center setup. Specifically, we have a projector, an HDMI switch, and multiple input devices connected to it (Apple TV, Steam Deck, Switch at the moment).
There are a few things that are suboptimal with this setup, but so it goes. One thing that’s been bothering me for a while is that there’s no great way for the switch I have to easily switch devices. It has a remote… but where’s the fun in that? (Plus we lost it for a few months).
So I took this as a chance to finally set up an IR transmitter with Home Assistant, using Zigbee Home Automation!
It was a bit confusing to get it all working, so I’m sharing it half so I can reproduce what I did if I ever need to or so that anyone trying the same can get it working.
A lot of what I did was based first on this blog post.
