We have designed 60 Channel ESP32 energy monitor board – N60 (ESP32 30 Channel CT Clamp Energy Monitor) for home automation project. It based on ESP32-S3-WROOM-1U (N16R8) wifi chip. The hardware have 60CH CT Clamp sensor INPUT ports + 6CH ZMPT101B voltage sensor + SD card + LoRa module + OLED display + free GPIOs. Ethernet+RS485+i2c extender 60CH high-accuracy energy meter ic-BL0910 with CT clamp. 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. it support use by ESPHome for home assistant for smart home automation DIY. N60 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 cloud service (official shop customer free 2 years), remote monitor and control device by webpage in anywhere. N60 support connect to your own cloud server by MQTT.

2. N60 have flash chip save the total energy data when N60 power off.
3. N60 use SD card to save energy data as excel file for every one hour.
4. N60 have i2c extender, easy extend i2c temperature and humidity sensors.
5. N60 have 2 free GPIOs use for sensor or KinCony G1 4G module.
6. N60 support use by MAX 250A CT clamp sensor. M30 support MAX 120A CT clamp sensor.
7. N60 support LoRa for KinCony ALR or KC868-A6v3 LoRa board.
8. N60 added new coefficient correction settings page
9. N60 use new Modbus protocol for user to read and config all channel data.
10. N60 support IFTTT, automatic send command by voltage or current or some other IF condition.

Good Evening,  hoping someone has done this or knows what I need todo.

I'm looking to add a larger screen to the A6v3.

I'm looking to add this type of screen, im having an issue with selecting the appropriate pins on the board & assigning the appropriate pins in my arduino code.

Thankyou in advance

Damien

Hi, I have a Kincony M30 and use it with ESPHome in Home Assistant.
Currently, my m30.yaml is configured from the following thread:

Today I tried updating my M30 with ESPHome version 2025.7.5 and received error messages related to led id

Help: Connect RS485 I/O modules to the Raspberry Pi 4 Relay Board (Server Mini) + Home Assistant OS


Hardware

• Controller/board: KinCony Raspberry Pi 4 Relay Board / Server Mini (link: https://www.kincony.com/raspberry-pi-4-relay-board.html)
  
• Modules I want to add: KinCony RS485 I/O modules (link: https://www.kincony.com/rs485-io-module.html)
  
• Planned system: Home Assistant OS (not Raspberry Pi OS), running on the Pi inside the board
  
• Use case: Wired wall switches and I/O around the house → one RS485 bus, multiple modules, stable & scalable for many installs
  

1. Daisy-chain several KinCony RS485 I/O modules to the Server Mini’s onboard RS485.
   
2. Control/monitor them from Home Assistant OS (HA Modbus if possible).
   
3. Best-practice for addressing many modules (bulk provisioning) without connecting a laptop each time.
   

• The board exposes RS485 via the Pi’s UART (I see pins marked GPIO14 = TX, GPIO15 = RX on documentation/pins).
  
• On Home Assistant OS, I cannot just edit /boot/config.txt like on Raspberry Pi OS, so I’m not sure about the correct way to enable the UART for the onboard RS485 under HA OS.
  
• I tried using generic HA Modbus config but I’m not 100% sure about the device path (e.g. /dev/ttyAMA0, /dev/ttyS0, or /dev/serial/by-id/...) and serial parameters (baud, parity, stop bits) for KinCony’s RS485 port on this board.
  

1. Wiring
   • Do I need a 120 Ω termination resistor at the last device? Are there built-in bias resistors on the Server Mini’s RS485 transceiver, or should I add my own?
     
   • Any max bus length / topology recommendations? (I’ll use daisy chain, not star.)
     
   
   
2. Protocol & parameters
   • Do those RS485 I/O modules speak Modbus RTU out of the box? If yes, what are the default serial parameters (baud, parity, stopbits) and the register map (coils/inputs/holding)?
     
   • If it’s not Modbus RTU by default, is there a Modbus firmware or config mode I should use?
     
   
   
3. Addressing multiple modules
   • How do I set unique addresses for each module? DIP switches? Command?
     
   • For bulk installs, is there a recommended workflow to assign addresses without hooking up each module to a PC? (Auto-addressing, scan/assign tool, etc.)
     
   
   
4. Home Assistant OS specifics
   • On this KinCony board with HA OS, what is the correct serial device path for the onboard RS485 (e.g., /dev/ttyAMA0)?
     
   • What is the recommended way to enable UART on HA OS for this board (since /boot/config.txt is read-only under HA OS)? Any KinCony-specific steps or an add-on?
     
   • A minimal, known-good Home Assistant modbus: YAML example for one RS485 I/O module would be super helpful.
     
   
   
5. Examples
   • Could you share example register addresses (coils/inputs) for:
     • Reading digital inputs from a KinCony RS485 I/O module
       
     • Controlling a relay output (if the chosen module has relays)
       
   • Any sample configs for more than one module on the same bus?

I just bought the KS868 A6 board and successfully flashed the firmware according to the instructions. However, after reconnecting the power, I can't detect the Wi-Fi access point. When power is applied, the red LED near the power connector lights up, and all relays click. No other activity on the board. Tried firmware KCS_KC868_A6_V2.2.13 and KCS_KC868_A6_V2.2.14. My board arrived in a very dented package, so I'm concerned about the Wi-Fi module. Is there any way to diagnose the Wi-Fi module? Could this issue be related to me temporarily using a DC 12V 1A?

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:

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:
