I have my first IoTaWatt set up and I’m trying to figure out how to configure submetering. In my application, I have two sisters living in separate apartments sharing 200A service. The fight constantly over energy costs, blaming each other for running up the bill There are two load centers fed from the meter. Shared services (geothermal heat pump and hot water heater) and connected to the load center I call ‘Unit 2’. I have CT’s on that panel and the relevant circuits for shared things. I also have CT’s between the meter and the other load center I call ‘Unit 3’
I’ve configured the IoTaWatt Outputs to show me:
Unit2 Watts = (Unit2_Main1 + Unit2_Main2) - (Geothermal + HotWater)
Unit3 Watts = Unit3_Main2 + Unit3_Main1
Shared Watts = Geothermal + HotWater
What I need help with is creating a report that I can use to give the ladies to show them KwH on a daily/monthly/annual basis. I’d love to get fancy with the reports at some point to correlate degree days, geothermal system time, etc…but first things first. Right now, I’m struggling with the basics and need some pointers to get started with:
- How to configure the Graph app on the IoTaWatt. It’s making some graphs, but I don’t know what I’m looking at.
- If/how I should set up EMONcms instead. (I got started, but I don’t know what I’m doing with the inputs and feeds)
- Where to find a simple, step by step setup guide for monitoring/metering in a way I can correlate to the bills. Since we’re billed in KwH…that’s a good start. Ideally, I’d like to translate that to $$$ because that’s all the ladies really care about.
