Hi All,
I recently found this online: 30 Channel ESP32 energy monitor board – M30
A brand called Kincony selling a 3-Phase, 10 clamps each, energy monitor.
It is ESP32 based. You can write your own code, but could also use what they provide. Based on the info on their website they use ESP Home which works with HA.
Price 200 + 12 USD shipping to EU. (Ex. tax/Import Duty)
They sell clamps for 5 USD each, ranging 10-100A. (lower is better/more accurate)
Smallest DL-CT03CL2.0 (wire needs to be inserted)
But also the more common SCT013 is sold (can be opened, without loosening wires)
Edit: Found out it also hosts a web interface + integrated MQTT support.
There’s also a 16 clamp version, single phase: iot ESP32 power meter – KC868-M16v2
Seems to be a legit company, selling lots of interesting IoT devices. Could buy from AliExpress also.
Although I cannot find that much about the units. Mostly video’s from the company itself.
Sure I could get this to send data to MQTT or Homey. But I was curious if somebody knows this device or some other brand which is comparable to find out the easiest way to integrate with Homey. I’m looking for 3-phase monitoring, at least 8 clamps each.
I’m aware of this project: https://shop.openenergymonitor.com
But it does not provide enough phases/clamps and it is way more expensive.
This might be an option aswell: https://www.athom.tech/blank-1/6-ch-energy-meter-made-for-esphome (LOL “Athom”)
Need to but several units ofcourse.
Let me know what you are using or thinking about these devices / my use case.
Thanks!
