Parts List

Parts List:

• CircuitSetup Split Single Phase Real Time Whole House Energy Monitor Kit
  • Be sure to include the '9v AC Transformer' -- Note that this is AC, not DC powered.
  • This device allows for monitoring of the RV's power usage.
  • Are there other options? Oh ya... but this is the easiest to use for most people and is what the software and processes below are based on.
• OpenEVSE Advanced Charging Station
  • You must have the 'Advanced' version so that it has integrated WiFi.
  • Beyond that, feel free to choose whichever option you're most comfortable with, from fully assembled, to just a kit ready for you to put together on your own.
  • Could you do this with a different device? Yes, but it requires a lot more work and isn't nearly as flexible. We've selected this EVSE ( Electric Vehicle Supply Equipment ) as a best of breed for this project.
• A Raspberry Pi
  • Raspberry Pi Zero W Starter Kit
    • The Pi Zero is sufficient to basic functionality, but isn't well suited for full local logging via EmonCMS, however you can still use a paid account on the EmonCMS.org site.
  • Raspberry Pi 4 Starter Kit
    • The Pi 4 has plenty of power to basic functionality as well as local logging via EmonCMS.  Note that installation and configuration of EmonCMS is well documented via this link.
  • Technically, any computer that you want to keep on all the time, that can run an MQTT server and NodeRED will work just fine. And if you knew what those services were before clicking their respective links, you can likely skip the Raspberry Pi and use whatever computer you like.
