  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.

  KC-868-A4 0v-5v ADC no where near accurate
Posted by: Fleetz - 01-13-2025, 01:44 AM - Forum: KC868-A4 - Replies (5)

Connecting the 0-5v generator to the A3 or A4 the ADC is reporting considerably lower voltages than what is physically generated and measured using a multimeter. 

Also if program an event using IFTTT using the ADC voltage to switch a Digital output it will not trigger the event?
E.G. IF AI3 is <=2.00v THEN DO1 to On  if I reduce the voltage to AI3 to less than 2.00v or even drop it down to zero volts DI1 output does not change state.

Hello, I’m very interested in trying your products and start using them as part of my home automation system based on home assistant. Since I prefer to use esphome to build my own sensors and stuff, integrating some of your products will take it to the next level. Making my system more efficient and more professional so I can start helping others by making step by step tutorial’s and reviews
