Good point - I was originally planning on using a Brultech and planned on just running Ethernet into the box. Switching over to the Iotawatt, I forgot that WiFi doesn’t penetrate Faraday cages very well. I’ll have to mull over getting WiFi into the box, because I’m a big fan of air gaps between my network and 240V, especially during thunderstorm season.

I can get 120V on the backside of the panel inside the garage - there’s a convenient 4-position outlet right there. As far as the equipment in the box, it’s a Demand Controller built by Dencor, and appears to be a solid, high-quality design. The best documentation I can find on it is this patent:
It’s intention was to monitor maximum demand (maximum kW averaged over an hour), and shut down some loads (Hot water heater, A/C, etc) if the house was taking too much power. This was used in conjunction with a demand-based electric rate to reduce cost. Unfortunately, due to its age, there’s not much information on line. I can read the part number on the CT’s - but it’s a Dencor part number, and Google pulls a blank on it.
The next time I get a chance, I’ll pull the guts out of the box and figure out the burden resistor, and see if I can correlate voltage across it with kW. I’ll try with a couple of loads - the water heater or Jacuzzi heater are always good ones (continuous, resistive load), the EV charger is probably a good one at higher power, maybe I’ll try to max out the current (turn on everything) and see what I get.
