Actually, everything is broken. It doesn’t show any status. The only thing that works is play audio.

3

It started working after playing some music first.

4

I’m having the same problem with reliability of set_volume not working for my HomePods.

Did you discover a reliable fix for scripts? I’m trying to adjust volume BEFORE playing some audio.

5

Unfortunately no, and I went away from that integration. Too unreliable for my use. It doesn’t work at all at the moment.

6

Thanks for response - I’ll file a bug report

7

Does anyone have an update regarding that volume control is only possible during playback and not before?

I really want to use only my HomePods and HomePod Mini’s and not mix them with Google Nest Mini’s.

set_volume worked for me last week, but then if failed on one HomePod but still worked on the others. Now it just fails on all of them. I removed all the HomePods and re-added them, but it still fails.

When I call it from node-red, I just get an error that says:
"Call-service error. "

Maybe AudioOS 16 broke the set_volume API?

9

facing the same problem. I am now using the logitech media server addon to control volume.

I used volume_set on the Homepod mini for a longer time. It still worked after updating the Homepod to iOS 16.3. Today after HA Update to 2023.01.1 volume_set stopped working and produces a TimeoutError. Have tried to play music before the automation with the volume_set starts did not help.

Postscript: I inserted a media_stop before the volume_set and then the volume_set works!
HA Version 2023.2.2 and iOS 16.3
