KC868 KCSv2.2.13 MQTT Update Issue - paulbalinnel - 06-27-2025
Dear Kincony
I use KC868-A8 with KCS v2.2.13[img]/local/images/tank0.png[/img]
MQTT is connected correctly
The sensor is configured for ADC1, via MQTT entity
State topic*
KC868_A8/2CBCBB658D44/STATE
Value template
{{ value_json.adc1.value }}
Ground Feeder Tank Level
29 minutes ago (the sensor does not update)
1,171 V
setting adc1
channel name: channel 1
unit: v
Custom value1 ( value when adc/dac is 0 ): 0
Custom value2 ( value when adc/dac is max range ): 5
Threshold ( Send mqtt when the change of sampling value is greater than it ): 1
if I switch any output, the MQTT message does come, but no MQTT message when the ADC value changes

what voltage input for test? 1.17V?
RE: KC868 KCSv2.2.13 MQTT Update Issue - paulbalinnel - 08-17-2025
hello yes I have a voltage from 0-5V on the analogue sensor
It was working well until this morning, the mqtt does not update on adc values, only if I switch the digital output, any then the new value of adc is sent
Pls help!!!

click the "gear" , set the "threshold" value for sensor, such as 1 , so that when data changed will auto feedback to mqtt.
RE: KC868 KCSv2.2.13 MQTT Update Issue - paulbalinnel - 08-18-2025
I have done this, and it does not report on MQTT
RE: KC868 KCSv2.2.13 MQTT Update Issue - admin - 08-18-2025
you can try set custom value1=0 custom value2=5 threshold=0.1 for a testing.
RE: KC868 KCSv2.2.13 MQTT Update Issue - paulbalinnel - 08-19-2025
I did try this setting, no mqtt update, only update is when I switch Output on or off
RE: KC868 KCSv2.2.13 MQTT Update Issue - admin - 08-19-2025
can you use newest KCS v2.2.14 firmware for a testing? erase all esp32 data, download newest firmware.
RE: KC868 KCSv2.2.13 MQTT Update Issue - paulbalinnel - 08-25-2025
please I need your help, i have ereased, i have set factory reset, i have used latest firmware
Board Model KC868_A8
Software Version v2.2.14
thre mqtt does not update on adc value changes
** I have used automation in Home Assistant to toggle output 8 on and off every 1 minute. this does update the the state on MQTT. a temporary fix.

take a photo of your PCB board.
