Hello, friends. Thank you so much for your products—I’ve been using them with great pleasure. However, I’ve encountered an issue while trying to set up your KC868-HAv21 RS485.

I connected it via RS485 to the KC868-A2, using the ESPHOME firmware. I added your component from GitHub, and the settings on the HAv2 are factory defaults. Controlling the digital outputs (D1-D6) works fine, but when it comes to changes in the state of the digital inputs, the ESPHome logs only show the following messages:

text
dump kc868_ha config, target_relay_controller_addr=1, switch_adapter_addr=10, bind_output=1
dump kc868_ha config, target_relay_controller_addr=1, switch_adapter_addr=10, bind_output=2

dump kc868_ha config, target_relay_controller_addr=1, switch_adapter_addr=10, bind_output=8  
found a kc868_ha board, target_relay_controller_addr=1, switch_adapter_addr=10, bind_output=1 (also bind output 1-8) 
What am I doing wrong? Could it be due to incorrect bind_output parameters? If so, which numbers should I specify?

I took the binary_sensor configuration from your GitHub and followed the instructions from your YouTube channel exactly. Thanks for your help!

before install smart home assisstant we need to connect to server 16 
but i cant connect, and when i check my connection to server 16 like this
how i can fix this ?

Looks like I need to buy this RF receiver module for the KC868-AI:

https://shop.kincony.com/products/rf-433...iQKBEdGYoh

Can I use a receiver and a sender module at the same time on this board? Kind of new to this, so sorry for the dumb question 

1. connect AG8 with USB-C cable to your computer, connect ethernet cable with router.
   
2. download tasmota firmware by web tool.
   
3. define Ethernet GPIO for module config option:

Ethernet (W5500) I/O define:

clk_pin: GPIO42
mosi_pin: GPIO43
miso_pin: GPIO44
cs_pin: GPIO41
interrupt_pin: GPIO2
reset_pin: GPIO1

* Used SPI W5500
* SPI_MOSI
* SPI_MISO
* SPI_CLK
* SPI_RST = Tasmota ETH_POWER
* SPI_IRQ = Tasmota ETH_MDIO
* SPI_CS  = Tasmota ETH_MDC

   
   

4. send "EthType 8" command from tasmota console

EthType Ethernet type.
0 = ETH_PHY_LAN8720 (default)
1 = ETH_PHY_TLK110
2 = ETH_PHY_RTL8201
3 = ETH_PHY_DP83848
4 = ETH_PHY_DM9051 (SPI)
5 = ETH_PHY_KSZ8081
6= ETH_PHY_KSZ8041
7 = ETH_PHY_JL1101
8 = ETH_PHY_W5500 (SPI)
9 = ETH_PHY_KSZ8851 (SPI)

   

5. now you will see the ethernet w5500 ip address:
   

we have designed Z1 by ESP32S3 + Tuya ZSU Zigbee 3.0 module. It based on ESP32-S3-WROOM-1U (N16R8) wifi chip. it support use by ESPHome for home assistant for smart home automation DIY. Z1 use KCS v3 firmware, it support home assistant auto discovery function by MQTT, so without write any config code (zero code) for home assistant. KCS v3 support KinCony board integrate to Loxone Miniserver and Apple HomeKit.

You can define RF and IR buttons to control TV or air conditioner or other IR devices by IR signal.
Z1 can pair with zigbee3.0 standard protocol products. create IFTTT command for zigbee sensor, so that zigbee sensor automatic send command to relay board or other devices using customize command.

You can write any code by Arduino IDE / Micro Python / ESP-IDF development tool to ESP32-S3 module. We will supply Arduino demo code for different samples. Everyone can modify and change the code for your own smart home automation system project.

Due the lack of 63amp contactors in 12v. It's possible to use a power supply with 24v for the  a24pro? Not for the relay.. to the unit itself? Thanks a lot!

1. Development Environment Setup
   • Arduino IDE (tested with both version 1.x and 2.x)
     
   • Official ESP32 core installed via URL:
     
     
     Code:

     https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json
     
     
   • Selected board: ESP32 Dev Module
     
   • Baud rate set to 115200
     
2. Sketch Upload
   • Tested official KinCony sketches for KC868-A2 with SIM7600
     
   • Tested custom sketches for sending AT commands
     
   • Tested with PSRAM disabled to eliminate
     
     
     
   • Compilation and upload completed successfully → ESP32 is working correctly
     
3. Connections and Power Supply
   • KC868-A2 powered with 12V as per manual
     
   • LTE antenna connected to MAIN port of SIM7600 (not AUX/GNSS)
     
   • Verified presence of power and indicator LEDs:
     • Red power LED solid on
       
     • Green modem LED blinking continuously
       
4. SIM Cards
   • Tested two different SIM cards in two different SIM7600E modules → no response
     
   • SIM cards confirmed working in a mobile phone
     
   • SIM PIN disabled
     
   • Contacts cleaned
     
   • Correct insertion verified
     
5. AT Command Tests from ESP32
   
   → no response
   
6. Serial Monitor shows nothing or “modem not found”
   
7. Alternative Checks
   • Attempted direct connection via USB MODEM to PC (drivers not easily available)
     
   • Tried alternative SIM slots and different LTE antennas
     
   • Evaluated alternative GSM modules (SIM800C, SIM800L) → working in other projects
     
   • Conclusion:
     The ESP32 works and communicates correctly via USB, but the SIM7600E module does not respond to any AT command, even after testing with two different units, proper power supply, and a suitable LTE antenna.
     

I have a KC868-A16v3 and I've created an IFTTT rule that says:
IF DI16 False and DI1 False then DO1 ON 1 then Delay 2 s then DO1 OFF 1 and it works but when i change DI16 to True it turns DO1 ON again for 2 seconds.  It only does it one time and then stays off if DI16 is True?
I am controlling the state of DI16 with a relay that I turn ON or OFF in HomeKit with a smart switch.  I am trying to use the KC868-A16 as an alarm control and DO1 is the siren so I don't want it to turn on again when I turn the system OFF (DI16 TRUE).  Any suggestions as to why this is happening and how to correct it?
