KinCony KC868-A6v3 ESP32 smart controller based on ESP32-S3-WROOM-1 (N16R8) wifi chip. Support 6 channel relay output, 2 channel 1-wire GPIOs, 16 channel free gpio on PCB. A6v3 include DS3231 high precision RTC clock chip. A6v3 support SX1278 LoRa or nRF24L01 wireless module. LCD display will show wifi and ethernet IP address. A6v3 have I2C bus extender and RS485 port. You can write any code by Arduino IDE / Micro Python / ESP-IDF development tool to ESP32 module. We will supply Arduino / ESP-IDF 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 or tasmota firmware for smart home automation DIY. A6v3 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. KCS v3 support KinCony board integrate to Loxone Miniserver. Support Apple HomeKit for Siri.

6CH dry contact inputs (optocoupler isolation, long distance circuit for MAX 500 meters cable)
2 buttons: S1:ESP32 Reset S2:ESP32 Download
1-Wire GPIO: 2CH (with pull-up resistance on PCB)
free GPIO on PCB: 7 ports
support install on din rail
software solution:
1. download KinCony KCS v3 firmware, so that work with multi protocol: HTTP, MQTT, TCP, RS485 modbus, config OUTPUT for “momentary” and “interlock” group functions. “KCS” support IFTTT function work locally without internet. It also support use by KinCony cloud server. KCS v3 support home assistant auto discovery function by MQTT, so without any config file for home assistant.
2. download firmware by ESPHome, integrate to home assistant or use by web service.
3. download tasmota firmware.
4. write your own Arduino or ESP-IDF code for your own requirements.
5. support tuya app if buy tuya license.
6. It is recommended to use home assistant and Tuya mobile phone app at the same time. So that remote control by internet using Tuya app, local control by LAN using home assistant app.
