I have a raspberry pi as part of the mix of my home automation setup. I have the raspberry pi announcing different events in the house (e.g., door openings, alarm being armed, etc). I wanted to see if anyone knows of a device handler that I might be able to use to control the volume of my raspberry pi device.
Im not sure if this helps… I have a pi running LibreELEC and the kodi device handler controls volume and i have bigtalker making announcements on the TV
bickyb, you could try TRIGGERcmd. It lets you run any command on your Pi by flipping a virtual SmartThings switch. So if you can figure out the command to change the volume, this should work.
