@Mykle1 No, it does not. You essentially pull the plug to turn it off. What I did at home was to plug it into a WeMo home automation outlet. I then used my phone to set up a schedule to turn the mirror off & on. And it ties into the Amazon Echo, so I can tell Alexa to turn the mirror off and on if I need it outside of the schedule.
The other downside is that the plug is only like 4 feet long. You may have to use an extension cord or (as I did) solder in an extension from a spare computer cord.
