Hello, in your video you are measuring 240V and 0.21A, which equals 50.4W. But in the video, it shows 32.3W. I have the same issue; the voltage and current are measured correctly, but the power and energy are not measured accurately. Is there any way to calibrate it to measure correctly?

Hello,

In my house I integrated the KC868 A4, A8 and A16 controllers (with KCS firmware) into the TapHome system. I used the Http Server for the connection. The static ip address is important here.

In the case of A8 and A16, the static ip can be set in the KCS, but in the A4 it is not available, as it only has wifi.

Is there a possibility for this? I ask for your help.

Regards, Zoltán

I have recently purchased an KC868-A32 and KC868-AG Pro in order to have DigitalInputs + Tuya + HomeAsistant + RF controll all at the same time on 32 relays.

I have uploaded via the flash_download_tool_3.9.2 tool the respective .bin files to both devices and then managed to access their IP and connect them to my WiFi.
On the KC868-A32 I have managed via the IFTTT part to configure the relays to work via the digital input pins.
On the KC868-AG Pro I have managed to learn 32 RF buttons and also manged to connect to the tuya App.
EDIT: I managed to control the relays in the local network via KBOX App

I have a couple problems/ don't know how to do:

1. how can I see the leaned RF buttons on the KC868-AG in the tuya app ? (or I need to "learn" them again from the tuya app?)
2. how can I control the  KC868-A32 relays via RF signals received by the KC868-AG ? (I have enabled on the A32  the TCP-Server, but I did not manage to make the 2 devices work with eachother)
3. what do I need to do in order to see the 32 relays from the tuya app, so I can control them from the app itself ?
4. in order to make the HomeAsistant part to work I assume I need to deploy the  HomeAsistant to a raspbery pi and then ? Do you have any tutorials on setting up the control of the relays from the HomeAsistant, if yes, please share me the links

UPDATE regarding question 2, after a couple of hours of debug of the C# MulitiBoardCtrlV1 code:

   1. from Postman I can make API GET calls to the  KC868-A32 IP : PORT and setting the body content to "RELAY-SET-255,1,0" or "RELAY-SET-255,1,1" and it works perfect on relay 1 without any noticeable delay between the API call and the relay actuating

   2. from the IFTTT of the KC868-AG I made an action IF RF1 THEN CUSTOME PROTOCOL1 , where  CUSTOME PROTOCOL1 is HTTP GET with message "RELAY-SET-255,1,0" and the URL and port of the A32 , this WORKS but with a HUGE delay beteween the RF remote button press and the relay actuating ~12seconds (while the direct api call from Postman working instant) , any ideas why ? or what I did wrong ? 

Thank you in advance, 
       Best regards, 
              Darius M.

How do I get access to the I2C bus? I want to add an LCD display.

TIA...

Hi, hope everyone is fine.

I give up... I need help. I am unable to store values in non volatile memory, so that if there is a power loss, and re-power, the value keeps the same... example, a temperature setpoint.

In my Arduino IDE environment I use: Node32s board (Is this the correct board?

This is the configuration I have in Arduino IDE:

GENERAL: 

#include <Preferences.h>

Preferences preferences; // Start preferences service.

SETUP:

  preferences.begin("almacenamiento-valores", false); // Start storage
  Serial.println("Escribiendo en NVS: 123");
  preferences.putInt("offset", 123); // Write a test value of 123 on the memory space called "offset".
 
  int valorLeido = preferences.getInt("offset", 0); // Reads the stored value.
  Serial.print("Leído de NVS: ");
  Serial.println(valorLeido); // Show the value that was stored.
  preferences.end();

Result I get on serial monitor: 

Escribiendo en NVS: 123
Leído de NVS: 0

Result: Writing the value was not successful. 

What am I doing wrong?
Would you advice using a different library for storing values?
Maybe the board I have selected on Arduino IDE is the wrong one?

Thank you for your help. 

BR, Juan

hi,
i'm trying to connect some solenoid valve to the board .
the solenoid use 24vac, when i connect the cable of the solenoid valve to the output 1, it goes on.
i don't undestand why

Hi Have a question about a how best to connect a signal that is about 1.2 - 2 volt. 
I presume I can not use the dry contact input 1 - 8 a they are 12v ?


Is there a way to get the board to detect a small 1.2 volt signal
Can I use inputs S1 - S4?

Thanks

I request a KC868-A4 equipment for education. I work for a school in Spain and we want to teach our students microcontroller programming and basic concepts of electricity and electronics.

Hi, I have the KC868-H32B board. I'm interested in how: can I connect the ZP13 Smoke Gas Sensor (like 7 sensors to one input slot)


All information about the module is provided here: https://www.winsen-sensor.com/d/files/manual/zp13.pdf
For this module's physical interface: XH2.54-4P terminal socket.


If this module is not compatible, could you recommend another one? But I need a module only.



Thx for your time and help who can replay me
