Hello,

I think there is an error in the Modbus document

The CRC is reversed, in the document is FA 3D for me is 3D FA

  Problem with names in port monitor - KC868_16A
Posted by: Poczwara13 - 01-14-2025, 01:24 PM - Forum: "KCS" v2 firmware system - Replies (5)

Hello,

I shared the recording with the problem in the link below:

https://drive.google.com/file/d/1NRPJGf5...KmdYB/edit

The problem occurs when the page is refreshed and affects the names of the input and output ports.

Alternatively, can you add a few additional characters to the port descriptions?

  S3 V1.0 firmware
Posted by: henkrouwenhorst - 01-13-2025, 09:46 AM - Forum: "KCS" v2 firmware system - Replies (3)

I am new to programming I have 3 x KC868 A16 boards I have successfully loaded firmware on to all of them and all function great. My problem is to load firmware on the Kincony S3 V1.0 in the " how to use online " section it refers to newer ESP32 S3 boards with the aluminium black case with screen and not the S3 Core board that I have.
I assume my problem is I am trying to load the wrong firmware on my board therefore I have no success. Could someone please give some guidance and a link to the correct firmware.
I want to use this to monitor tank level and temperature and link to my Home Assistant.
It seems there is not many people posting about this specific board in your forum.
