  Questions about Analog Inputs KC868-A16
Posted by: Decilitr - 01-19-2025, 08:00 PM - Forum: KC868-A16 - Replies (9)

Hi all!
I received my KC868-A16 board and now experimenting with it. My goal is to use it for Home Assistant.
Digital inputs and outputs work fine, but there are some confusing points with analog inputs.
I would appreciate clarification.

1. I used the lines from the example .yaml file and it turned out that because of the lines
------------------------------------
    filters:
      - lambda:
          if (x >= 3.11) {
            return x * 1.60256;
          } else if (x <= 0.15) {
            return 0;
          } else {
            return x * 1.51;
          }
------------------------------------
the measured voltage values were greatly inflated. So I removed these lines from my .yaml file and the voltage values became correct.
What were these lines in the original example for anyway?

2. When the same voltage is applied simultaneously to all four analog inputs, the spread of readings between them is no more than 5%. This is very good accuracy, but can it be increased by changing the parameter "attenuation: 11db" ?

3. When connecting each of the analog inputs to ground, the voltage value is not 0V but 0.14V
Is there any way to fix this?

4. And the main problem. When the input voltage changes from minimum to 3.14V, its value is displayed correctly. However, when the input voltage increases from 3.14V to 5V, it stops changing and always shows 3.14V, which is obviously wrong.
What is the problem here?

  analog input resolution 30%erro

Hello

Can you tell me the resolution on the analog inputs.
Because for 1.5v in I visualize 2.01v which is 30% error..
That's a lot

Hello

i have a problem with the NFP, in fact impossible to have a correct display with the right time zone.
What is the reading cycle of the NTP server?


The internet connection is good.
This NTP server works well on all my computers

The capture 3 is the time of my computer

  KC868-ATC v1.4 connect to H32 rev 2.3
Posted by: SrgX13 - 01-18-2025, 04:23 PM - Forum: KC868-ATC / Tuya adapter V2 - Replies (5)

Hello,
I have been trying for a few days to set up the KC868-ATC v1.4 with Tuya module to connect to KC868-H32 rev 2.3 and control the relays. I managed to set the KC868-ATC  Tuya module and connect using Tuya mobile App (Android), however the button/switches are not responding. 
The weird part is that I can connect to  KC868-H32 using Vircom and the IP seems to be set to 192.168.2.160 (we are using 192.168.2.x ranges). From what I have seen in the referred videos is that I should also be able to connect using the browser however this is failing.  KC868-H32 is connected to the router through Ethernet cable

I have even tried to set  KC868-ATC v1.4 to use RS232 instead of wifi. This had the same negative results.

If you require more information please let me know.
Please help me with some ideas how to set this system. I assume that I might have to change the firmware on KC868-H32 as in Tuya it was showing H32B PRO
Thank you very much and I wish you a great day
