Plugs power increased automatically

I’ve never seen this before. Any reason why this would happen? Spike to 34W?
Connected to my Yamaha amp. No routine or anything triggered this.

Assuming 4-5W is standby mode, and 30ish Watts are when you are playing music.

Does the amp wake up from standby overnight to check for firmware updates or anything like that?

Yeah the 4W is standby mode. I wasn’t playing anything at that time in the morning, I was asleep.

Hmm, good point. But I don’t think so. Had it for well over a year now and this is the first time I’ve seen this.
