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 Y

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, 3840

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?
