KinCony T64M Tiny ESP32 Smart Controller released

Posted by: admin - 08-01-2025, 04:56 AM - Forum: News - Replies (2)

KinCony T64M tiny ESP32 smart controller based on ESP32-S3-WROOM-1U (N16R8) wifi chip. Support 64 channel MOSFET output, 4 channel 1-wire GPIOs, 3 channel free GPIOs. T64M have 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. T64M 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.

Code:
/*

 * Made by KinCony IoT: https://www.kincony.com

 *

 * This program reads 24 input states from two PCF8575 I/O expanders and 

 * controls a corresponding 24-channel relay module. 

 * When an input pin is LOW, the corresponding relay is turned ON (LOW means ON for the relay).

 * When the input pin is HIGH, the corresponding relay is turned OFF.

 *

 * Pin Definitions:

 * - SDA: GPIO 8

 * - SCL: GPIO 18

 * - Input I2C Address 1 (inputs 1-16): 0x24

 * - Input/Relay I2C Address 2 (inputs 17-24 and relays 1-8): 0x26

 * - Relay I2C Address 3 (relays 9-24): 0x25
