You use the volume buttons on your phone.

I finally upgraded by TV and am really enjoying being able to use my AppleTV > HomePod Stereo Pair as the audio output for any sound sent to the TV by other devices and game systems.

I like the quality, and it mostly works well. Records to hksv, shows up in ATV, detects people and such.

My criticisms: it should be portrait instead of landscape, so I can see packages on the ground, plus my entryway is narrow.

I wish it would ring the original house doorbell when hardwired. Nest could do it. I have it ring the HomePods/Ecobee but not as loud or pleasant as physical chimes.

It requires a small plugged in hub. I was able to hide this easily but be aware. The hub is also your bell if you don’t have HomePods or similar.

I wish it were a little smaller, but not a huge deal.

Twice I’ve had it stop charging from the hardwire for no known reason, discover it when the built in battery backup ran out. Power cycling the circuit at the circuit breaker resolved it, but it was a small annoyance. Hasn’t happened lately.

Can someone chime in and compare the speed and integration compared to HomeKit/HKSV native solutions?
