Bose wave music system turns on by itself when there is no one in the room or even in the house.

Looking for reason Bose system turns itself on.

Alarm set?

Alarm set?

It would only be the alarm if some spurious signal or EMI set it to go on. The alarm is never used as such.
(The radio is in a den with a computer and TV.)

I don't have personal experience with this but there is a very similar question to yours where the 'expert answer' offers the solution that it is caused by interference from Wifi. The suggestion is to move the wave to a different part of the house and see if the problem persists, if it doesn't then at least you've identified the cause.

I guess at that point you would need to look at moving your router or whatever away from the wave.

It would be your power supply when you leave it on standby any flutuation in the electricity will caus it or any other device on standby to auto start like a television etc and that would be all it is most likely unless you have it set up to wake itself with phone lan etc but I guess a very slight flicker in your power could be the culpurit which could mean there is a bad connector on the transformer near your house or even a bit furthur away this also means you will most likely be experience a power outage soon.
