@jbouwh I've read that page, but I don't really see anything extra to add there. The current state of the integration is that volume level updates only after another event occurs (power state change or playback state change), with this change the entity state updates as soon as volume is changed. Did you have a specific change in mind?

Did you have a specific change in mind?

Not directly. It was just a check. CI tests will be fixed soon.

Tested with a home pod mini.

Asked siri to increase volume and new state was reflected almost immediately
