Water Heater thermostat setting (Now: how water heaters work and half detecting 220V devices)

@samwooly1,

A whole thread on those tags - not sure we know exactly what they represent yet, but you shouldn’t use them for any of your calculations.

One chart says +3000 and another ~+750 for same device

The device-specific page is correct. Essentially, the power meter is calculating wattages in a different way that is causing issues with how it displays the wattages for some devices, based on the half-second resolution of the Power Meter.
