. If you're a home automation nerd, these words mean something to you. You are an extreme form of pure nerd, and we envy your ability to invest in things like replacement light switches while the rest of us scrimp and save because now we have to watch TV in an extra dimension we never asked for. Anyway, that Z-Wave network you might have? Well, the Bulogics Smart Grid Controller bridges a Zigbee power meter into it using a new Sigma Designs chip, so you can track all your power usage easily and do something called "end-to-end load shedding," which either helps you save power or requires a painful medical procedure. You're welcome.
