CRC Errors with ESP Home & N10203060_KU_V20_260324SP

Posted by: edalquist - 05-21-2026, 03:10 AM - Forum: N60 - Replies (3)

I updated the ARM firmware to N10203060_KU_V20_260324SP and then tried flashing the ESP Home config from https://www.kincony.com/forum/showthread.php?tid=9157

I'm now not getting any data and the following logs repeating over and over:

There are no other changes to the system, just completed that ARM firmware update and flashed the example ESP Home config

Questions about KinCony F16

Posted by: yazeed - 05-19-2026, 10:58 AM - Forum: F16 - Replies (1)

Hi KinCony,

I want to buy the KinCony F16 16-Channel ESP32-S3 Removable Relay Controller for my car (offroad)
https://shop.kincony.com/products/kincon...1712290981

I have watched all the videos by KinCony engineer on YouTube, but I would like direct confirmation from you on the following questions:

- Does the F16 work with DC lights and DC devices? What is the max amps or watts per channel in DC?

- How much current can each channel handle on 12V DC continuously?

- Is there Home Assistant integration, and can I connect the F16 to Home Assistant via WiFi?

- Can the F16 tolerate heat of 60-70°C inside the vehicle?

- The F16 needs 12V DC power. Can I connect it directly to my vehicle's 12V battery, or does it need an external Buck Converter / TVS Diode for protection against car voltage spikes (alternator load dump up to 100V)? If protection is needed, what product do you recommend for vehicle installation?

- Can I connect an external switch to an input so it triggers the relay directly, without waiting for Home Assistant?

- Have any customers used the F16 in cars or vans before?

Thanks,
Yazeed

Las Firmware ?

Energy calculation for negative currents

Posted by: GWS - 05-17-2026, 12:22 PM - Forum: N30 - Replies (4)

The energy calculation seems to be always positive and not take into account negatieve power.

Although current was negatieve and power too the energy is positive.
Also noticed that in a phase where current was pos at first and neg later the energy keeps adding which makes the energy calculation incorrect.

Energy is defined as a 32-bit float so it should be able to handle pos and negatieve loads.

Suggestion for Kincony board for project

Posted by: igor_quintal - 05-16-2026, 11:24 PM - Forum: DIY Project - Replies (2)

Hi team!

I have a smart home running with Home Assistant for quite some time. To automate all the lights, I created a central hub where all lights connect on my breaker panel (as the picture shows). I went with a very simple setup, using a Sonoff Basic flashed with Tasmota for each light switch. It works! But it is not great, and some relays are starting to fail. Also, buying new ones and flashing them with Tasmota is a little bit of a hassle. I wanted something better like a multiple channel relay. And that's when I recently saw KinCony!

It seems perfect to what I need. But there are so many board options available that I'm a little confused of which one to get. I want something that is reliable and safe, to be used in a DIN rail with up to 16 channels. Integration with Home Assistant is a must, but from what I saw, all boards support ESP Home. So what kind of board do you guys recommend? I saw that there were cheaper and more expensive ones, but I did not get the difference between them.

Thanks a lot!

Reset Total Energy only works per chip

Posted by: GWS - 05-14-2026, 07:00 PM - Forum: N30 - Replies (1)

	Hello, I have made some changes to my setup and one of the reasons is that the calculations were not correct. Tried to reset the BL0910 chips but Clear all does not seem to clear the Total Energy values . Just found out that "Clear Energy 1/2/3" so per chip did actually work.

Factor settings and calculations

Posted by: GWS - 05-14-2026, 09:27 AM - Forum: "KCS" v3 firmware - Replies (2)

Hi,

I see some weird bahavior on my N30 that I do not understand:

Using CT with factor 1000:1 and after measering the actual curren with MID approved device I found that factor 2.1 was the best.
When I save the factor 2.1 it results in 2.0999... etc and that might very well be because of how the factor is binary processed in the chip.
So initially I started with setting all factors to 2.1 (for testing I have now set CH01 to factor 2 and CH02 to 1)

But on Channel 2 (first 901 chip) I got strange values and the Power Factor keeps changing in the header of the dat for that chip.
On the other two chips it stays on 1.0000 and the data looked correct.

When I move the CT connector for 1..10 to the position of the 11..20 I see that CH12 is displaying the expected values.
Looks like CHIP 1 is behaving differtent from CHIP 2&3.

Any idea what could cause this?

Related to this I would like to know how to best set the factors I it necessary to set all columns with same factor? (Please provide a field for the default setting for all columns)
Power = Voltage * Current
Energy = Power over time accumulated. It is not fully clear if I need the factor (2.1) there also, or should it be 1 since the power is already corrected.

Thanks,
GWS

N30 - Modbus-TCP

Posted by: GWS - 05-14-2026, 08:57 AM - Forum: "KCS" v3 firmware - Replies (4)

Hi,

I am trying to get the N30 to work as a modbus device that I can read from via TCP on port 502. Could not get it to work on the IP address of the N30

Hooked up a Hi-Flying EW11 TCP to modbus converter to the RS485 port in modbus mode and that does work. Can see all the registers for chips on address 100/200/300
I was assuming that the setting

TCP Server: enable
Protocol: Modbus
local port: 502
modbus local addr 1

Would be sufficient to read the registers via the N30 IP address on port 502

Whatever I try I do get a time-out

Port 502 is open if I test with ModbusDoctor or Powershell I get connected but no readings at the expected adresses.

Also tried with setting Modbus-RTU-v2 and a virtual COM port without any responce. Please provide instructions if this should work and if so how?

Thanks,
GWS
