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.
