I use a Generac Neurio energy monitor to record my PV production and my power consumption on each phase of my house power. I upload the data from my Neurio to PVOutput using a Pi 3B running Debian OS through the Crontab function which runs my task every five minutes and uploads the data through the PVOutput’s API.
This is the output so far today.
The Delta Energy is the kWh used for the last 5 minute reporting period. During the early morning hours the only things running are the “always on” items which draw power when idle such as the TVs and computer peripherals or kitchen appliances. The refrigerator shows on phase A and a freezer in the garage shows on phase B. Spikes are usually kitchen appliances. I have chosen to display PV production on this graph and have turned off three items normally displayed which appear grayed out.
There are other energy monitors available which can be utilized in this manner. People with three phase power might also be interested in a way to monitor all phases for consumption. In that case you would need a monitor capable of monitoring three phase power.
Kudos to PVOutput for providing the ability to construct this display.
