Retro smart meter

Vintage multimeter becomes energy monitor.

This is a variant of my Power consumption reader which shows the returned/used power of my house with a moving coil meter to see. It is built into an old multimeter.

As an extra, it has three LEDs that indicate whether more is returned than is consumed (green), whether power is generated but not enough for the entire house (orange) and whether no power is generated at all (red).
