I am doing a lot smart home control via NR. The most frustrating problem I have is the inability to have definite volume control of my sound bar. I generally use a hoarmony hub/remote. The remote can do volume up and down. I can also do that via node red, but as anyone who has experience with harmony knows, it is just sending IR commands to the equipment and so can’t know the actual volume setting unless the device can be sent a specific volume number.
Does anyone know of a sound bar that can be sent a specific volume number either via IR or any other method that Node-Red, Hubitat, zigbee2mqtt, mqtt or homebridge? I list the other 4 as I already have working interfaces to them.
