KinCony KC868-AGv3 ESP32S3 Smart IR RF Controller released

Posted by: admin - 06-11-2026, 08:32 PM - Forum: News - No Replies

ESP32-S3 Smart IR RF Controller – KinCony KC868-AGv3
KinCony KC868-AGv3 is a smart IR controller designed for smart home automation and IoT projects. It is based on the ESP32-S3-WROOM-1U N16R8 module, with powerful performance and rich interfaces for infrared, RF433MHz, and custom GPIO expansion.
KC868-AGv3 supports Home Assistant, ESPHome, Arduino IDE, MicroPython, and ESP-IDF development. With KinCony KCS v3 firmware, it also supports MQTT Home Assistant Auto Discovery, so users can integrate sensors and decoded IR signals into Home Assistant without writing configuration code.

ESP32-S3-WROOM-1U N16R8 module
Built-in IR receiver
IR sending via 3 GPIO channels
2 independent IR extension cable ports
Built-in RF433MHz receiver
Built-in RF433MHz sender
Built-in buzzer
18 free GPIO ports on PCB

Supports KCS v3 firmware
MQTT Home Assistant Auto Discovery
Zero-code integration with Home Assistant using KCS firmware
Suitable for smart home, IoT, IR control, RF remote control, and automation projects

Home Assistant Integration
KC868-AGv3 can be used with Home Assistant in two ways.
Users can configure the device with ESPHome YAML for customized automation projects.
It can also run KinCony KCS v3 firmware. With KCS v3 firmware, KC868-AGv3 supports MQTT Home Assistant Auto Discovery. Sensors and decoded IR signals can be automatically discovered in Home Assistant, making setup much easier without writing configuration code.
IR and RF Control
KC868-AGv3 includes both infrared and RF433MHz functions.
The built-in IR receiver can be used to learn and decode infrared remote control signals. The IR sender can transmit IR signals through 3 GPIO channels, including onboard IR output and 2 independent IR extension cable ports.
The RF433MHz receiver and sender allow the controller to work with 433MHz wireless remote controls, sensors, and RF devices.

How to enable 2 IIC buses at the same time?

Posted by: ronpsc - 06-11-2026, 02:54 AM - Forum: KC868-A128 - Replies (1)

	Dear Sir, May I know how to enable both IIC buses for DI and DO at the same time for KC868-A128 in Arduino IDE? I can only enable one each time, so that I cannot program the board to trigger outputs when inputs changed. Thanks, Ron

	Hi Team I'm currently researching for a Water Controller System. So i need a main controller to research. If it works better, useful for the community. This is a fully automated water level controller and monitoring system with advanced systems. So if you support me, i can build a solution for that.

M16v2 and SCT013-050

Posted by: SixSixOne - 06-10-2026, 10:20 AM - Forum: KC868-M16 / M1 / MB / M30 - Replies (5)

Dear Sir,
I have bought a M16v2 recently and try to make it work with SCT013-050 50A/1V sensors (https://www.aliexpress.com/item/10050092...1802lqJyc9) with the jumper positioned in the "V" measurement on the board.

I've used the last yaml code you provided (also attached) however it is not measuring anything.

My house has 3 phases and I have already checked all 3 phases as they are coming from teh grid as well as from a socket.
I've never received any measurement the Amperage is always 0A and the RAW measurements 0.11A, 0.12A, 0.13A

Any idea what is going on?

Tks a lot
