My idea is to monitor power consumption and automatically turn off the outlet based on time and power consumption (e.g. at night, but only if nothing has been running for a while).

Most important is monitoring the power consumption, in particular I want to get the data to a Raspberry Pi.

My thoughts what it should do:

  • Can measure power consumption and ideally turn output on/off
  • Must have an open interface and not send any data to a server
  • Maybe Zigbee/Z-wave instead of WiFi for power efficiency?

Is there such a wireless outlet, what should I look for? Does my idea even make sense from a technical perspective? I'm a computer scientist, so my electronics knowledge is limited.
