  "KCS" v3.27.2 firmware BIN file download
Posted by: admin - 09-11-2026, 02:40 AM - Forum: "KCS" v3 firmware - No Replies

new version improvement:

1: Fix native Tuya MQTT TLS verification for the Central Europe data center by adding DigiCert Global Root G2 to the embedded CA bundle while retaining Go Daddy G2 and existing TLS verification settings. (if you using tuya license, need update this firmware)

2: Add RAM-backed application logs to the System page with authenticated polling and preserved serial output.

  extend KC868-A16v3
Posted by: robi932 - 09-10-2026, 01:22 PM - Forum: KC868-A series and Uair Smart Controller - Replies (2)

Hello,

I bought a KC868-A16v3 ESP32-S3 16 channel GPIO module and realised that I need 10 more outputs. What would be the best approach? buy another one and run both? or is there any alternative?
I am using it to connect the outputs to SSR to have no mechanical noise on activation.

Thanks

Question KC868-A16 Outputs Y01-Y16: 12V LED works weakly when OFF and turns OFF when ON
Posted by: miguelsa - 09-09-2026, 03:53 PM - Forum: KC868-A16 - Replies (1)

I recently purchased a KC868-A16 and I am currently testing the outputs before integrating the board into an automation project.

I am having an unexpected behavior with the Y1-Y16 outputs and would like to confirm whether this is normal or whether there may be an issue with the board or its configuration.

I am powering the KC868-A16 with a 12V DC power supply through the DC input. I also connected the 12V+ from the power supply to the 12V+ terminals of both output terminal blocks, one for Y1-Y8 and another for Y9-Y16.

For the load, I am testing a simple 12V LED with two wires, red (+) and black (-). I connect the red wire to 12V+ and the black wire to an output such as Y9.

I initially tested the outputs using ESPHome with Home Assistant. I also tested the hardware independently using Arduino IDE and direct I2C communication with the PCF8574 at address 0x25, which controls Y09-Y16, so the behavior is not related to ESPHome or Home Assistant.

With the Arduino test, I directly write 0xFF and 0xFE to the PCF8574 to toggle P0/Y09.

The behavior is:
P0 = HIGH / 0xFF
Y9 measures approximately 10 to 11V
The external 12V LED is always ON, but only at low brightness.

P0 = LOW / 0xFE
Y9 measures approximately 0V
The external 12V LED turns OFF

When I connect the same 12V LED directly between the 12V+ and GND terminals of the board, it lights at full brightness as expected.

Therefore, the power supply and LED appear to be working correctly.

I also tested several outputs, including Y1 and Y9, and they show the same behavior.

Could someone from KinCony please clarify the expected electrical behavior of the Y1-Y16 MOSFET outputs on the KC868-A16?

The board is a KC868-A16 Rev. 1.6.3
I would appreciate any guidance regarding the correct wiring and the expected output voltage/current behavior for this revision.

  N10 - ESPHome - ARM CPU streams continuously, Modbus requests never transmitted
Posted by: luzozo13 - 09-09-2026, 08:39 AM - Forum: N10 - Replies (3)

Hello,

I am trying to integrate a new N10 board with ESPHome (v2026.8.0) and Home Assistant. After extensive testing I have isolated the problem precisely and hope someone who has successfully set up an N10 with ESPHome can help, or that KinCony staff can clarify some undocumented behaviour.

Board: KinCony N10 (ESP32-S3-WROOM-1U N16R8, 16MB flash)
ESPHome version: 2026.8.0
Chip: Freshly erased with esptool before first flash

SYMPTOM

ESPHome's modbus_controller never transmits a single request to the BL0910 ARM CPU. The UART RX line (GPIO10) is flooded with data from the moment power is applied, before ESPHome sends anything. Because ESPHome's Modbus component sees a perpetually busy bus, its frame-guard logic refuses to ever transmit. Every log shows thousands of "Clearing buffer of 2 bytes — timeout after partial response" messages and zero TX lines.

DIAGNOSTIC STEPS COMPLETED

1. Bare UART only (no modbus: component)
RX line completely silent for 60+ seconds. Confirmed the ARM CPU does NOT stream data unprovoked.

2. modbus: component, slave address 1, 115200 baud (ESPHome Devices reference config)
Continuous noise on RX, zero TX ever logged.

3. modbus: component, slave address 100, 38400 baud (per KinCony's own protocol document)
Same continuous noise, BUT real data bursts appeared embedded in the RX stream. This is the only configuration where the ARM CPU visibly responds — confirmed it is responding to address 100, not address 1.

4. All baud rates tested: 9600, 19200, 38400, 115200 with slave address 100.
Best results at 38400 (real data bursts visible). Other baud rates produce background patterns consistent with framing mismatch.

5. Boot drain lambda (on_boot reads and discards all RX bytes before modbus_controller initialises)
No effect, TX still never appears.

WHAT I BELIEVE IS HAPPENING

When ESPHome's modbus: component initialises, something causes the ARM CPU to enter a continuous streaming state. Once streaming starts, ESPHome can never transmit. Without the modbus: component, the ARM CPU stays completely quiet.

QUESTIONS

1. Does the N10 ARM CPU require the KCS factory firmware to run first and perform an initialisation before it will behave as a standard Modbus RTU slave? Has anyone successfully used ESPHome on a freshly-erased N10?

2. Can anyone confirm the correct slave address? Our testing points to 100, not 1 as shown in the ESPHome Devices reference config.

3. Can anyone confirm the correct baud rate? KinCony's protocol document says 38400; the ESPHome Devices reference says 115200. Our best results were at 38400.

4. Is there a known way to suppress the ARM CPU's startup streaming from ESPHome, so the Modbus component can get its first request out?

  OLED not found in I2C scan
Posted by: Armsp0 - 09-07-2026, 01:28 AM - Forum: KC868-A6v3 - Replies (1)

I have an OLED screen 1.5" 128x128 IC: SH1107. I can use this screen on esp32 dev board or ESP8266 without issue. If i connect to my KC868 A6 I2C bus it does not get found with i2C scan. I find its address using I2C scan on another device as 0x3C. if i go ahead and use that address in a EspHome yaml configuration to try and force a connection it fails. could this be pull up resistor issue?
