We have designed 30 Channel ESP32 energy monitor board – N30 (ESP32 30 Channel CT Clamp Energy Monitor) for home automation project. It based on ESP32-S3-WROOM-1U (N16R8) wifi chip. The hardware have 30CH CT Clamp sensor INPUT ports + 3CH ZMPT101B voltage sensor + SD card + LoRa module + OLED display + free GPIOs. Ethernet+RS485+i2c extender 30CH 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. N30 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.

what’s mainly different between N30 and M30:
1. N30 use by KCS v3 using ESP32-S3 large memory CPU, M30 use by KCS v2 using ESP32 CPU.
2. N30 have flash chip save the total energy data when N30 power off.
3. N30 use SD card to save energy data as excel file for every one hour.
4. N30 have i2c extender, easy extend i2c temperature and humidity sensors.
5. N30 have 2 free GPIOs use for sensor or KinCony G1 4G module.
6. N30 support use by MAX 250A CT clamp sensor. M30 support MAX 120A CT clamp sensor.
7. N30 support LoRa for KinCony ALR or KC868-A6v3 LoRa board.
8. N30 added new coefficient correction settings page
9. N30 use new Modbus protocol for user to read and config all channel data.
10. N30 support IFTTT, automatic send command by voltage or current or some other IF condition.
software solution:
1. download KinCony KCS v3 firmware, so that work with MQTT protocol. “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. use PC software to read all data from N30.
4. write your own Arduino or ESP-IDF code for your own requirements.
