Description

The CircuitSetup Split Single Phase Energy Meter can monitor the energy usage in your entire home in real time!

Please choose an AC transformer and current transformers (most often 120A CTs will work with your mains wires with 200A service), if needed. They are NOT included in the base price.

With the Split Single Phase Energy Meter you can:

  • Save Money!
    • See exactly how much money is being spent on energy in real time
    • Find appliances that are using too much electricity
    • Calculate energy usage for a single room to divide an energy bill fairly among roommates
  • View & Gather Energy Data
    • View the energy usage of your entire home
    • Calculate how much it costs to charge your electric vehicle
    • Remote energy monitoring for vacation or rental properties
    • Review and graph historical energy data
  • Be Informed!
    • Independent of your power utility’s meter
    • Set up alerts for over or under usage

3 reviews for Split Single Phase Real Time Whole House Energy Meter Kit – Programmed ESP32, ABS Box

  1. Guillermo

    Works with 220v?

    • circuitsetup

      Yes it does. You just need to calibrate your AC transformer to correctly measure voltage. We do not stock 220v AC transformers.

  2. Key

    If I purchase this kit, what else do I need to do?
    Do I need to do any programming?
    Can it measure energy production from Solar? (Can this read negative reading from meter?)

  3. Christ

    Hi,
    from where can i buy the complete kit. From this website or crowd supply? If I connected to only 1 phase can I disable the second AC transformer?
    Thanks
