  m16v2 energy meter - calibration issues
Posted by: PapaC - 04-17-2026, 06:04 PM - Forum: KC868-M16 / M1 / MB / M30 - Replies (13)

Hi, hopefully someone can help where I'm having issues calibrating the m16v2 energy meter in the UK which is on 240v with 1 phase.

Currently I am only focusing on CT_15 which is the Grid, I have a Shelly EM using a 120a1v CT clamp which is on the same line as CT_15.

When attempting to calibrate with 2 resistive loads (not at the same time) it just simply falls out of line when then seeing real world usage after, for example I had turned on a 3000w kettle, the Shelly shown the correct load so I then calibrated the figures as recommended in Kincony code, then I tried a 1500w electric heater but instead of the load being somewhat close to the expected reading, it was instead 1900w.

Additionally, when on normal realworld load where the house has typical appliances on which would bring it to about 300w on the Shelly, the m16 instead reports that its 600w.

I can confirm that I have connected the m16 to the consumer unit as recommended so then it shows what the voltage is, which I can confirm is accurate when compared against the Shelly which reports basically the exact same voltage.

All clamps are 1v, and are shown in order of what they're used for along with the amp:

  • 1 - Shower - 50a
  • 2 - Cooker - 50a
  • 3 - Kithcen Ring - 30a
  • 4 - Dish Washer - 30a
  • 5 - Washing Machine - 20a
  • 6 - Tumble Dryer -  30a
  • 7 - Reserved
  • 8 - Reserved
  • 9 - Fridge - 20a
  • 10 - Reserved
  • 11 - Reserved
  • 12 - Reserved
  • 13 - Reserved
  • 14 - General Ring - 30a
  • 15 - Grid - 100a

  Complete Home Assistant configuration.yaml with yaml anchor for mqtt integration A16
Posted by: korl - 04-16-2026, 09:14 PM - Forum: KC868-A16 - Replies (3)

Hello everyone,

I see many people asking for configuration.yaml for A16, A6..etc.

Every person is spending time, building their own yaml-file.

Could you just provide a complete template for each board (A16, A6), that combines all switches, binary_sensors, ADCs, DACs, Temperature sensors... in one text block, combines as one device (with yaml anchor) ready to copy into Home Assistant configuration.yaml?

I think it would make the boards more attractive, if there is an easier start for integration.

Does anyone want to share their configuration.yaml?

Best wishes

  KC868-A16 rev1.6 firmware
Posted by: maurus44 - 04-15-2026, 06:42 PM - Forum: "KCS" v2 firmware system - Replies (5)

Hello,
I am using a KC868-A16 board (REV: 1.6) and I would like to confirm which firmware is correct for this device.
I have been flashing firmware using the ESP32 Flash Download Tool (v3.9.2). So far, I have tested the following firmware versions:

  • KCS_A16V3_V3.24.3 → I was not able to access the controller after flashing
  • KCS_KC868_A16_V2.2.4 → I could access the controller, but the input table was incomplete / partially missing
At the moment, I am using:
  • KC868_A16_V1.0.10 → this version works, and I can access the controller
My question is:
Am I using the correct firmware for KC868-A16 REV: 1.6, or is there a newer recommended version that is fully compatible?
Thank you in advance for your help!

  4 - 20 mA adc not giving correct values

I am testing the KC868-AIO 4-20 mA analog input with a Fluke 705 Loop Calibrator, but I am not getting correct values.

Source voltage: 24 VDC
Channel AI-16 (see red wire). Black wire is disconnected.

Power source for signal is the same as the source for the AIO board.

Monitor Configuration:

Custom value1: 32
Custom value2: 180

Signal generated: 4.000 mA
value provided: ~52 (it should be 32)

Signal generated: 8.000 mA

Signal generated: 16.000 mA

Signal generated: 20.000 mA

  N60 Sensor channel label
Posted by: marekd1 - 04-14-2026, 02:44 PM - Forum: N60 - Replies (15)

Hello,

Is there a way to assign custom label to each channel defining monitoring node function on local N60.  

As far as I know I think you can do this on Kincony Cloud page but I am looking to do this at local N60 node level.  Example Chanel 1  Server, Channel 2 Sump, etc...

If not could this be added in the update firmware release?

thank you!
