BeeWi took the wrappings off its Mobot prototype power plug at Mobile World Congress in Barcelona. The Mobot is more than just a timer for your electrical gadgets. The plugs can communicate with each other and your phone. Individual plugs can be turned off and on using an app. You can set schedules or get alerts from the plug's built-in motion detector. Battery backup and a temperature sensor are nice safety features. Home automation is hot and the Mobot could be a solid contender in the power plug department.
