KC868 A8 + Home Assistant + DS18B20+ - Наиль - 07-16-2026
Good afternoon! I bought two KC868 A8 and KC868 A16 boards to use with Home Assistant. I found configuration files for these boards on a forum, and all the inputs/outputs work, but I can't connect the sensors. Help please.

download KCS v2 firmware, set the sensor by "sensor" webpage.
here is KCS v2 online guide: https://www.kincony.com/esp32-kcsv2-firmware.html

Good afternoon! But I'm using a board with Home Assistant. If I install the KCS firmware, will I be able to control the KC868 board using Home Assistant?
RE: KC868 A8 + Home Assistant + DS18B20+ - admin - 07-17-2026
sure. there are two way use for home assistant.
1: download KCS firmware, integrate to home assistant by MQTT.
2: config by ESPHome.
RE: KC868 A8 + Home Assistant + DS18B20+ - Наиль - 07-17-2026
I would like the second option.
2: config by ESPHome.
Please write a configuration file fragment for the KC868 A8 board to connect multiple DS18B20 sensors to a single input using the 1-Wire Bus

I don't know how to find out the address of the sensor. "address: 0x1234567812345628".
Here's my configuration file, which passed the check, but it doesn't show the temperature.
sensor:
- platform: dallas_temp
one_wire_id: bus_S1
name: "S1 Temperature"
update_interval: 10s
- platform: dallas_temp
one_wire_id: bus_S2
name: "S2 Temperature"
update_interval: 10s
one_wire:
- platform: gpio
pin: GPIO14
id: bus_S1
- platform: gpio
pin: GPIO13
id: bus_S2
