CurrentCost to LEDborg energy monitor "orb"
Takes serial input from a CurrentCost energy monitor, and based on a user-programmable threshold (in the switch node), turns a LEDborg (multi-colour LED display) green, amber or red. Works particularly well with a cut-out ping-pong ball over the LEDborg as a diffuser.
