Audio controls in Home Assistant using MQTT

In a previous post, I shared some software I wrote to get my amp to listen to power and volume commands from my TV. Now, I’ve added the ability to control it from MQTT as well. It integrates with Home Assistant, so I can have a nice view that essentially serves as a remote control. It’s quite handy for adjusting volume if I’ve put some music on then walked away.

It’s a bit limited right now since the MQTT feature is just bolted onto the driver that was intended for the CEC use case, but there’s definitely room to expand it in the future.

More info on the project is available on GitHub.
