Powermiser is a wall/bench mounted plate that provides a button you can push in a deadmans switch style to get 15mins of power from a GPO socket. Repeat presses will increase the timeout in 15 min increments to a maximum at any moment of 60min. Time remaining is indicated by 4 RGB LEDs and alarms sound at programmed intervals. Countdown can be increased to the maximum at any time.

This aims to solve 2 problems:

  • Unused GPO's get turned off saving power
  • Requires a person to attend the powered devices at a minimum of once per 60min, which removes ability for things like cnc devices or 3d printers to be left unattended.

Timer settings might be customised per installation via dip switches or headers.
