How to connect SMOKE DETECTOR SENSOR with KC868-A64?
#1
Hi, how to connect Smoke sensor (https://www.kincony.com/smoke-detector-sensor.html) with KC868-A64.
These are the pins present in smoke sensor:
RED: 12V
BLACK:GND
WHITE: COM
ORANGE: Normal open
YELLOW: Normal close

I have uploaded KCS_KC868_A64_v1.0.27 firmware in the controller. What is the MQTT topic for receiving data from digital pins?

you can connect "smoke sensor" WHITE wire-COM with A64 board's GND terminal.
"smoke sensor" ORANGE-Normal open with A64 board's digital input terminal.

Hi, My MQTT broker is live in my local network at mqtt://192.168.1.4:1883 .
I put these mqtt details in the Network page but its not connecting and shows "disconnected" in Monitor page.
Can you please help. Currently the board is in AP mode.

if you use wifi, you need set WIFI to STA mode, connect to your router. so that let A64 and your mqtt broker in one local network.

I configured STA mode (https://snipboard.io/fd3vqJ.jpg) as well and connected to the same network in which MQTT broker is running. Still showing disconnected (https://snipboard.io/tLY0kB.jpg)


Please let me know if I'm missing something to connect to MQTT broker.

I subscribed to KC868_A64/D4D4DAE11DF8/STATE with my pc mqtt client but no message. I tried "Set beep output" but not working.

you can try connect to KinCony's mqtt cloud server:
mqtt ip: 47.254.155.180
mqtt port: 1883
username: mqtt
password:123

if connect well, check your network or mqtt broker.
