I recently setup Home Assistant and trying to make the house as smart as possible. I have a current setup in our house with speakers in each room and each room has and independent volume control for its specific room. I have a Chromecast audio hooked up to a receiver which outputs to these speakers at a set volume. This has worked like a charm for the past 6+ years.
I can’t seem to find any devices that accomplish what I’m trying to do. Basically a digital volume control which can be controlled remotely in HA.
