Hello all,

I am working on a project that requires integrating Kincony's KC868-A8 relay controller into a custom automation system, and facing some challenges related to communication protocols, data handling, and device reliability;

• Communication Protocols
  
• Data Handling
  
• Device Reliability
  
• API/SDK Usage
  

Here is "KCS" firmware for KinCony MB DC energy meter board.

KCS firmware for MB
   
Monitor all channels for Current, Voltage, Power
   
   
setting for MQTT connect to your own private MQTT cloud server. 
   
Support use by Tuya mobile phone app for remote monitoring. Note: "Tuya" and "MQTT" can't enable at the same time.
   

my KC868-Server Raspberry Pi4 local server is no longer communicating with Home Assistant. You cannot toggle switches on and off while in Home Assistant. Home Assistant does not recognise all the ESP boards

Here is "KCS" firmware for KinCony M30 AC energy meter board.

KCS firmware for M30
   
Monitor all channels for Current, Voltage, Power, Energy, Frequency, chip Temperature
   
   
setting for MQTT-1 and MQTT-2. MQTT-1 connect to your own private MQTT cloud server. MQTT-2 use for home assistant MQTT broker. If you want to use Auto Discovery function, just enable it.
   
M30 can be auto discovery in home assistant.
   
all KinCony M30 entities use in home assistant directly.
   

Hello everyone,
I recently purchased a KC868-A16 Rev:1.6 board. I've installed the USB driver, downloaded the latest firmware, and the corresponding download tool. However, when I try to upload the firmware, I encounter an error with the following message: "Error 2-Sync Fail."
The error message suggests checking the chip datasheet to confirm that the strapping pins' status is correct. I’ve attached a screenshot of the error for reference.

Here’s a brief overview of what I’ve done so far:

1. Installed the USB driver for the board.
   
2. Downloaded the latest firmware and download tool.
   
3. Attempted to upload the firmware, which resulted in the error message.
   

The memory on the ESP32-WROOM-32E is not enough for my application.

Can I replace it with ESP32-WROOM-32E-N16R2 or ESP32-WROOM-32E-N8R2?

I believe GPIO 16 and 17 (rs232) are a problem. I would like to keep rs232 if possible. If not possible also OK.

Also, are there plans for a new version for the A6 board with ESP32-S3 with PSRAM?

Hi team,
I am very new to home automation, & have received my AIO board and was unable to find the user guide. Is it under a different name or the same as another that is already there?
Does this apply to the software i load as well?
Thanks

Hi.   Had everything working this past winter with the 868-A4S board and home assistant.

I recompiled my code and installed it on the device.   It installs, then hangs, can't connect or anything.

If I say prepare for first use from home assistant, it sets the board type (to esp32-c3-devkitm-1).

This installs, and runs normally, but not all pins are available to the program, and when I press the reset button it defaults back to the old firmware that shipped with the board (where it cycles the relays and outputs on power up).

So..

Have any examples of home assistant yaml for current revision of home assistant that should install and work?

Or any feedback on what the board type should be?   esp32dev doesn't work for me.

Thanks in advance.   I don't think I missed any step, but I am probably doing something wrong.
