Description

Introducing the CircuitSetup Expandable 6 Channel Energy Meter – the ultimate tool for monitoring and analyzing energy consumption in your home or workspace. This cutting-edge meter provides you with accurate and detailed measurements, helping you make informed decisions about energy usage and efficiency. Whether you’re a homeowner, a facility manager, or an energy-conscious individual, the CircuitSetup.us 6 Channel Energy Meter is your key to understanding and optimizing energy consumption.

Up to 6, 6 channel add-on boards can stack on top of the main board to allow you to monitor up to 42 current channels in 16-bit resolution, in real time, all at once! Each add-on board can measure an additional voltage channel.

With ESPHome loaded on the ESP32, the 6 Channel Energy Meter can easily output energy data to the new Home Assistant Energy Dashboard. Individual circuits, solar, as well as whole house energy can be imported into Home Assistant.

5 reviews for Expandable 6 Channel ESP32 Energy Meter Main Board

    I purchased one of these to test out and see if I could get it working. It didn’t take me long to get it all figured out. This board is amazing and does exactly what is says that it will do. Amazing. I will be purchasing 6 more boards. It is not cheap, but it is the best solution if you want to monitor all your circuits. I’m getting continuous data readings sent to my PC, all the time. I can select any day that I want and look at the data for that day. I have found several devices in my house that are “off”, but consuming .5 amps of power at all times. Completely amazing board!

    Great product and even better service.
    Couldn’t be happier with it.

    I purchased this board a couple of weeks ago because I wanted to monitor my energy usage. I want to know both the quantity of energy and the time of day that I am using it in preparation for possibly converting some of my energy needs over to solar. It is an exceptional tool for showing my energy usage over time. I have had a few surprises on appliances and equipment that I thought would be big energy users, but are not actually turned on as much as I had expected. After a little reading and study, I found the instructions to connect it into Home Assistant running on Raspberry Pi to be straight forward and fairly easy to implement even though I new to both of these products. I used ESPHome to connect to Home Assistant and am now recording my energy usage. I have just purchased an expansion board and more CT’s to be able record and monitor 12 channels, instead of going into my panel and moving around CT’s. Thanks for a great product!

    Love the board, found the ESPHome installation good, however the box shipped to me does not fit this board. Guessing the got a bad batch. Hopefully someday I will get a replacement. Probably been needing a two level box by then.
    Have trouble getting a needed current transformer (200Amp), must have had a run on them. trying to get some help with a possible substitute. Not much luck yet getting a response (few days). Must be overwhelmed with too much business with the new HA Energy release…

    This is a solid product that will provide the AC circuit data you need, amps, active power, apparent power, reactive, power factor, volts, frequency.

    I have one of these main boards plus an add-on board monitoring 12 locations on a sub-panel. Another main board with two add-on boards is on the way to monitor 18 locations on my main panel. I’m eyeing another main board to monitor my shop that hosts my solar array.

    At the power company interface I have two of the split-phase boards monitoring the four main legs feeding my split 2x200A Main Panel.

    The sample configuration files found on the CS github make configuration just, easy. Modify the sample file, flash ESPHome and your circuit data lands in Home Assistant, or in the native application if you choose.

    You do need (should have) a quality clamp-on amp meter to calibrate the CTs you use. That too, is easy and well explained on the github.

    Do yourself a favor and include the case in your “Bundle.” It makes for a clean and permanent installation. Of course, you need a power supply, the CTs themselves and an ESP32 board.
