ESP32-S3 temperature humidity sensor modbus convertor – TR

KinCony TR ESP32-S3 sensor convertor module based on ESP32-S3-WROOM-1U (N16R8) wifi chip. It have 4 channel 1-wire GPIOs and RS485 interface. Many free GPIOs on PCB. It convert MAX 4 channel sensor (DS18B20/DHT11/DHT22) temperature and humidity value to RS485 modbus protocol. You can write any code by Arduino IDE / MicroPython / ESP-IDF development tool to ESP32 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 or tasmota firmware for smart home automation DIY. TR 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 Apple HomeKit.

software solution:

1. download KinCony KCS firmware, so that work with multi protocol: HTTP, MQTT, TCP, RS485 modbus. “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 arudino code for your own requirements.
