I have a 24v 20A power supply which I intent of using to power a bunch of LED strips. As each "DC" port can handle 10A maximum, and B16M has two DC ports, can the B16M be used to control said LED strips?
What about dimming, can the PCF8575TS I2C I/O expander handle updates fast enough that dimming can be accomplished? What about just adding jumpers from the ESP to the I/O expander outputs to basically do PWM directly if PCF8575TS can't handle it?

Thank you

Hey there,

i got a projekt, for that i bought the KinCony KC868-A16 and an RaspberryPi4.
Currently I´m trying to connect the Kincony board and Raspberry with Mosquitto to Node Red.
Mosquitto is running and I´m able to send and recive messages when i try it from my Pi to recive a message on nodered.
I´m able to ping the KinCony Board and connect with it with WLan to change the settings on the Board.



What am I missing that I don´t get the connection via MQTT and NodeRed?
When it would work, how does the topic for the MQTT message have to look like?

Thanks in advance for the help.

I have 2 boards installed using KS2 firmware: K868-a32 and k868-a16s

What's the best way to set them up, i would like to use home assistant and MQTT but still want light to work in case home assistant breaks.

Should i setup boards using IFTTT, and only integrate MQTT for some scene automations, remote control and reading relay states?

Dear XuWei,
I am writing to request your assistance with a project involving a dancing fountain. I have a set of inverters for the fountain, and I would like to use the KC868-E16S to control them via RS485 modbus
So far, I have successfully managed to turn the fountain on and off using the output relays of the KC868-E16S. However, I need guidance on how to write a custom command, specifically to control the fountain’s speed and toggle its operation via the RS485 protocol. This means that the KC868-E16S will be responsible for managing and controlling the inverters in the fountain via RS485 Modbus.
Please note that the buttons is connected to the input of the KC868-E16S, and I am currently operating with KCS Firmware V2.2.12.
I will also attach the inverter manual for reference.
I appreciate your assistance and look forward to your response.
Best regards,

On my KC868_A16 board, I'm trying to activate Output 1 when I trigger Input 1.

I have set Output 1 as shown in my attached image but I can not get Output 1 to activate.

Hello,

I have connected a new KCS868-A6 v1.3 by USB to my Mac and powered with a 12V power supply. I intend to use it with ESPHome and Home Assistant.

I do not see a usbserial port (no /dev/cu.*), and I do not see a wifi network.

When powered up or S1 is pressed, it clicks all 6 relays so something is alive in there!

What am I missing?

Bonus question: Is there an easy way to add an Ethernet module that works with ESPHome?

Thanks.

Hi there, i just got your kincony a32 pro smart controller and i am using the kcs v3 firmware and the controller keeps saying tuya offline and trying to connect and the led blinks constantly. i do not see a option to disable it in the kcs v3. Can u please help me out ? thanks.

Hello!

I hope you will be fine. I bought 4 KC868-A16 for trial purpose for my company. If suitable we will buy more But I am not able to program it until now. So I was thinking Kindly Can I get your WhatsApp so that any of your technical support Staff can guide me how to program KC868-A16 with  Arduino IDE software. 

I had connected the power and ethernet port with my laptop for programming. Also I had selected the board as Nodemcu32s and selected the right port. When I start uploading the your demo code, I don't why the program doesn't upload and give me the following error;

"Sketch uses 316512 bytes (24%) of program storage space. Maximum is 1310720 bytes.
Global variables use 21008 bytes (6%) of dynamic memory, leaving 306672 bytes for local variables. Maximum is 327680 bytes.
esptool.py v4.8.1
Serial port COM5

A serial exception error occurred: Cannot configure port, something went wrong. Original message: PermissionError(13, 'A device attached to the system is not functioning.', None, 31)
Note: This error originates from pySerial. It is likely not a problem with esptool, but with the hardware connection or drivers.
For troubleshooting steps visit: https://docs.espressif.com/projects/espt...oting.html
Failed uploading: uploading error: exit status 1"

Could you identify what I am doing.ad connected the power and ethernet port with my laptop for programming. Also I had selected the board as Nodemcu32s and selected the right port but I don't why the program doesn'
I will appreciate your help in this regard.

I just received the M30. And I don't know how to get it to work. I haven't found any documentation or user guide for the M30.
My scenario is to configure the M30 to provide measured data via MQTT to other systems.

I want to connect to M30 and configure it. But it looks like the ethernet connection is not working.
If I connect the M30 to the switch, LED on the ethernet port doesn't blink.

Hello,

After installation of IDE 2.3.4 on Windows 11 and inserted the link "https://dl.espressif.com/dl/package_esp32_index.json" in the preferences  The "esp32 by espressif Systems 3.1.1" is installed
I see only under "Tools" the board "esp32"
Under sep32 I see a lot of modules but no ESP32 Arduino Module. I cannot connect via the Com3 to my KC868-A16 REV:1.6
Can anyone help me with installation of the correct board and module to get the communication with my KC868
Great thanks
