Hi,

I came across your Youtube channel and was wondering if you would help me design a solution for my Off Grid Expedition Camper Truck.

I would like to monitor and ultimately control all items via Alex Hub.

I am currently in the process of building the vehicle and all electrics are going to be supplied using Victron System (Inverter), via Batteries/Solar/240V hook up.

The system will have a 240V AC requirement with 17 Circuit Breakers and a 12V Circuit with 36 fused (Spade type or can be railed DC Breakers).

Is this something you can help with?

I wait your reply.

Many Thanks

Dion Mack

hi, i would be interested in using kc868 M16-V2 with home assistant. but i would need to know the power of each channel (and not the current) can the board calculate it for each channel?

Good afternoon, I have a Kincony F16 and I am interested in removing Tuya from the .yaml file and keeping only ESPHome. I do it another way to connect from outside the home and I don't need Tuya. Could you tell me exactly what I have to remove so that nothing remains of  en el archivo .yaml "F16-HA.txt". I'm afraid I won't be able to connect if I delete something by mistake. Thank you.

IIC Bus:

SDA:GPIO11
SCL:GPIO12

PCF8575/XL9555:U22 (output1-16): i2c address:0x25

PCF8575/XL9555:U17 (input1-16): i2c address:0x24

Note: after 2026-11-01 KinCony begin use XL9555 i2c extend chip. you can use KCS v3 "SYSTEM" webpage to scan device show the model or config by ESPHome to scan i2c bus, will find the chip model.

Hi all!
I received my KC868-A16 board and now experimenting with it. My goal is to use it for Home Assistant.
Digital inputs and outputs work fine, but there are some confusing points with analog inputs.
I would appreciate clarification.

1. I used the lines from the example .yaml file and it turned out that because of the lines
------------------------------------
    filters:
      - lambda:
          if (x >= 3.11) {
            return x * 1.60256;
          } else if (x <= 0.15) {
            return 0;
          } else {
            return x * 1.51;
          }
------------------------------------
the measured voltage values were greatly inflated. So I removed these lines from my .yaml file and the voltage values became correct.
What were these lines in the original example for anyway?

2. When the same voltage is applied simultaneously to all four analog inputs, the spread of readings between them is no more than 5%. This is very good accuracy, but can it be increased by changing the parameter "attenuation: 11db" ?

3. When connecting each of the analog inputs to ground, the voltage value is not 0V but 0.14V
Is there any way to fix this?

4. And the main problem. When the input voltage changes from minimum to 3.14V, its value is displayed correctly. However, when the input voltage increases from 3.14V to 5V, it stops changing and always shows 3.14V, which is obviously wrong.
What is the problem here?

Hello

Can you tell me the resolution on the analog inputs.
Because for 1.5v in I visualize 2.01v which is 30% error..
That's a lot

Hello

i have a problem with the NFP, in fact impossible to have a correct display with the right time zone.
What is the reading cycle of the NTP server?


The internet connection is good.
This NTP server works well on all my computers

The capture 3 is the time of my computer

Regards
