I use multiple Harmony Home Hubs to IR control my AV equipment and mini splits in multiple rooms with the driver linked below (local). Harmony has discontinued the line, but you can still get them on eBay for $30, and they are still supporting their functionality, so I have had no issues adding new devices (just did a few weeks ago), updating activities, etc. You can add/program essentially any device (even if not in the list of supported devices) and manually add any command from your existing remote and start activities or send individual commands if needed. No RF support though, if you need that.
