I've identified an issue with my M16 board whereby the SH31 sensor becomes disconnected after the setup() function and can no longer be read.  I've tried a number of variations on the bus settings, but there seems to be no effect.  The relevant setup() code is this:

I've made available via GitHub project a C++ project for the M16 board.  This application will read CT sensors on the Kincony KC868_M16v2 board and calculate power usage. It allows per sensor configuration and sensor correction algorithms. Periodic MQTT messages are emitted with various readings and configurations can be set via MQTT messages and saved into non-volatile memory.   It also includes an STL to allow you to print a rudimentary cover for the board which will allow it to be surface mounted via screws.

The code is too large to post here, along with the numerous class files, so I'd direct you to Github:  https://github.com/LouPaloma/KinconyM16-PUBLIC

The code is marked with a number of TODO/FIXME, so patches and pull requests are welcome, although I have limited ability to test since my own unit has been "deployed".

(Also, I have identified an issue with the SHT31 sensor, but I will open a separate thread for that.)

Good afternoon,

I want to control 2 different devices fans with 0-10v capabilities of one KC868-A4S but I'm not sure about wiring.

For the first fan from AFL Motors (file 122) these are the connections that I plan :
 - 0-10 VDC yellow on fan with AO1 on KC868-A4S
 - GND blue on fan with GND after AO1 on KC868-A4S

for the second fan from Aermec (file 22) these are the connections that I plan :
 - 0-10V IN V2 blue on Aermec with AO2 on KC868-A4S
 - 0V V1 grey on Aermec with GND after AO1 on KC868-A4S

Am I right or wrong ? If I'm wrong, what are the right connections ?

Thanks

Hello,
In a previous email I mentioned that I am using the SIM 7600 module with the ESP32 S3 WROOM 1U, however I can't use the serial monitor in order to receive information (I can't see data), I would like to know if you have any advice for the ESP32 S3 set up in Arduino firmware. See my below set up in tools menu:



I followed you recommendation with ''USB CDC On Boot'' = ENABLE, and now I have below information in the Serial Monitor:

I think I need to change something else in the Tool config but I'm not sure.

Thanks.

Hi!
I purchased some KC868-A8 to install in my new home and I'm now testing them. 

I flashed one with ESPHome but the switches don't change relay state unless I program an automation in Home Assistant to do that (if input1 on/off change alternate relay state). Is it there anyway to configure this without HA? Should I use another firmware for this?

I also like to know if there any other device that can work with dimmable leds.

Hi,
I received a new A8 board, downloaded KCS with  success, off/on the board. But I cant see the board on my net. Even with your tool udp scan. The board is on the same switch than my PC.
Udp scan can see my two other kincony board. I tried both kcs V2, the V1..no luck.

No problem with Tasmota, I have a wifi access to the board (but not via wire).


I remember , installing them last year was not esay for me, spending too much time.
I have 110 ish IP address on my Lan, many vendors, so far switches from shelly ,dingtian.
I added kincony for the 1wire support. But man, am I stupid for having so much problem with the K boards boards or is my english broken? I hope so and that you will point me to the solution.
Would be so easy for me, to have new board coming with kcs de facto.

Also, I tried to integarte it on HA. I thought it would be easy like the videos show : just copy and paste! . No way, I am fighting with the yaml syntax . I know I should learn the yaml syntax. But you could simplify my job by posting yaml files not text ( or it is hidden on the website?) . Yes I am dumb with yaml. But for newbies like me, we would be more enclined to buy kincony stuff.

Question:
When kcs starts for the first time, is dhcp activated? on wired lan first , right?


I posted my request by email, as you suggest when I contacted via ali. You reply that I should go to the forum. So please for new buyers, on ali , suggest to contact you on the forum.

Thanks

What are the options for connecting an A6 to a Raspberry Pi 5 with a cable, followed by integration with Home Assistant?

I already have these 433MHz sender and reciever modules are these suitable for the KC-868-A4?

Or are the sender and recievers that Kincony sell designed specifically to work only on the KC-868-A4 board?

I'm using a B16M to control a home automation project. It's using a 24V power supply and the B16M is switching a set of 24V relays that switch the 230V mains.
I can switch the relays via Home Assistant and via the ESPHome dashboard but I can't switch the relays using the digital inputs. If I ground a digital input pin I can see the state change on the Home Assistant and ESPHome dashboads but the relay dose not operate.
I am using the B16M ESPHome yaml for home assistant code from the forum which I haven't changed.
Regards
