No ethernet communication - philippe - 09-02-2026
Hi, I just received a new board. I cant accees it through ethernet. I guess the kcs comes with dhcp enabled. if yes, I cant see it with a scanner, I cant find it with the kincony scan tool. I reflashed with esp home and the A8 yaml file, no way. I reflash with the kincony flashing tool and kscv3, no way. The port I am using on the switch is fine, thats the one I am using for my PC . By the way, the board is V1.7.1, I is it the new board? I hope so, I just got it, expecting to use it with 1wire sensors expecting the kcs v3 to solve my 1wire instable sensors issue.
Thanks

you need download KCS v2 firmware by usb-c cable firstly.
here is KCS v2 online guide: https://www.kincony.com/esp32-kcsv2-firmware.html

Is it an old module? cant use v3? where is kcsV2?
Is it an old module? cant use v3?
error
just downloaded the kcs v2.20 from your site
ok flash is ok with your tool, but do not work with the esp one. Please tell me if this board can resceive V3. I need a board for 1wire sensors, the site says v3 solve the stability pbs of the sensors.
The flashing process does not stop, its stayed on sync and the page is filled with dots, and goes on, goes on. First time I have so many pbs with my 5 kincony boards.
Frustrated with that, and by not having received a board that can hold V3

Question, all oy my board are kcs v2. To get my 3m long 1wire sensor to work correctly, should I flash with esphome and another firmware? or should I move to another hardware

KCS v3 use for KC868-A8v3 board, that made by ESP32S3.
