I’ve been scratching my head over the past month or so about the mystery “something” that moved my Always On from around 160W to about 500W. I figured it had to be something seasonal since it changed in mid-Sept.
Turns out it was quasi-seasonal… We had an end-of-summer party where we showed a movie outside. I inadvertently left two of the amps inside my Yamaha multi-room AV receiver turned on. It would have been easy to see if it was the main amp, but only tiny red indicators show for the other three amps. Should have also noticed it was toastier than usual in the electronics cabinet, but I hardly ever open it. Have now hooked both the Yamaha and my Sonos to TP-Link HS110 Smartplugs to keep a closer eye on them going forward.
