RE: how to integrate KC868-A8 to home assistant by MQTT - admin - 08-03-2025
support use by DS18B20, DHT11, DHT22 sensor. these sensor will work with KCS firmware and show in home assistant by MQTT integration.

I installed a DHT22 sensor.
How can I forward it to Home Assistant via MQTT?

Thank you, the sensors have been added, but the values are not updated. Tell me how to force the values to update.
RE: how to integrate KC868-A8 to home assistant by MQTT - admin - 08-06-2025
for example, in your KCS sensor webpage, you need set the "threshold" for temperature and humidity.
temperature=0.1
humidity=1

temperature=0.1
humidity=1

if you use KCS firmware , can't add other relay module. if you config by esphome, you can add i2c extend relay module , such as DO8 8 channel i2c relay board.

Dear sir
I have followed your instructions on setting up a KC868-A8 in Home Assistant and have got on the overview the 8 inputs and 8 outputs but they are unavailable and have been every time I have made changes
I have deleted the device a number of times and rein stalled it with different firmware but every time it is the same result.
I am thinking that it is not connected to MQTT in Home Assistant but I can see it connected to MQTT on the Kinconny web page and can operate the relays and see a temperature probe I have installed I can see the inputs operate and in Node Red on Home Assistant I can read the inputs and outputs.
The one part I am having a real problem with is the MQTT part in HA I have tried to add a user in the logins as per your instructions but get an error message when I try to change the file. See attached file below. The files are in the folder where I attach files to
I have also downloaded the log file from the A8 and it shows a warning message see below
I have tried I think everything except the right thing but I do not know what that is I am hoping that you will be able to help me I have also attached a screen shot of the Esp Home Page below
Yours

step4: replace all ID by your own board, you can check ID from KCS "index" webpage.
step5: save the yaml file by click "save" button. Then ready to restart of home assistant.
step6: go to "setting" -- "system" webpage, restart your home assistant.
step7: Now you can found new entities in "Setting" -- “Device & services" -- "Entities" webpage. all have listed, you just add to home assistant dashboard is OK.

do you want to use esphome? if YES, just use by yaml file, not need to use mqtt.
esphome yaml file: https://www.kincony.com/forum/showthread.php?tid=2367
note: esphome and KCS firmware , can't work at the same time.

Hello,
I recently integrated all inputs and outputs to HA, unfortunately I stuck with temperature sensors.
I'm using DS18B20 and I see the values while listening in MQTT, but from some reason I cannot read the value on dashboard, I`m more than sure that something is wrong in my config.
