  H32B+switch termenal board+Tuya adapter
Posted by: Saif Kitany - 05-10-2024, 08:35 AM - Forum: KC868-HxB series Smart Controller - Replies (3)

I want to control my H32B controller by switch terminal board and Tuya adapter in the same time. I connected these 3 devices with rs232 cable splitter, and then i have no response from either switch terminal board or tuya phone app!

Why is this??

I will add a picture of the rs232 cable splitter I used.

  KC868-A16S Analog input 4-20mA connection
Posted by: nicolouts - 05-10-2024, 07:48 AM - Forum: KC868-A series and Uair Smart Controller - Replies (4)

Hello,
I have a KC868-A16S device and I want connect 3 Analog sensor on it.
My sensor provide a 4-20mA signal with 24VDC voltage.

So I need to convert one of my signal to 0-5V with 250 ohms resistor and connect to CH1 or CH2
But I want to be sure, if I can connect directly my 4-20mA directly to CH3 and CH4 without damage the ADC of the ESP32.

I know that maximum voltage for ESP32 ADC is 3.3VDC, is there a protecting circuit on KC868-A16S to prevent damage?
What the purpose of LM224 on the drawing?

Thank in advance.

Regards

Nicolouts

  Unable to receive IR signals using ESPHome
Posted by: pscaffardi - 05-08-2024, 09:57 AM - Forum: KC868-AG / AG Pro / AG8 / Z1 - Replies (7)

Hi everyone!
We are playing with KC868-AG, we already tested many features (IR sending, etc...) but we still have problems using IR receiver. Is there a complete esphome configuration out there?
I used this one for I:

remote_receiver:
  - id: receiver_ir
    pin:
      number: GPIO23
      inverted: True
    dump: all

climate:
  - platform: daikin      # adjust to match your AC unit!
    name: "Daikin AC"
    transmitter_id: transmitter_ir
    receiver_id: receiver_ir

When i upload esphome i get the console full of "Pronto" data (but there is nothing sending IR codes here; i already tested with other IR receivers):

PHP Code:
[09:26:28][I][remote.pronto:236]: 0000 006D 0001 0000 0005 0181 06C3

[09:26:28][I][remote.pronto:236]: 000F 0023 000F 0181 06C3 


Only when i point my daikin IR remote to the Kincony and press a key i get something different printing out for a second:

PHP Code:
[09:26:28][W][component:237]: Component remote_receiver took a long time for an operation (81 ms).
[09:26:28][W][component:238]: Components should block for at most 30 ms. 

And then the pronto messages fills my console, again.

Is my esphome configuration right? Suggestions to correctly decode IR signals?

  How to use the radio remote of Kincony ?
Posted by: vincen - 05-08-2024, 07:44 AM - Forum: Suggestions and feedback on KinCony's products - Replies (6)

Hi

I have bought months ago some little black round remotes from Kincony to use with some existing 433Mhz devices. Unhappy I need to reprogram them to use them with an other device. Unhappy the product is not listed on Kincony website and guy that answers on Aliexpress for Kincony is just dumb (sorry to say) or don't speak english at all which is very boring Sad
Does someone have the explanations to learn Radio codes into it ? I remembered it needed 2 buttont to be hold together but not sure which ones now :/

Thanks for help

  KC868A-4 RF433MHz decoding.
Posted by: franco.demei@gmail.com - 05-06-2024, 07:04 PM - Forum: KC868-A4 - Replies (17)

If I understood the meaning of the sample code. Once uploaded the code, opening the Serial monitoring to Arduino IDE I should see the code transmitted  from 433 MHz remote control.  I don't understand why to the monitor I don't see anything. I'm sure that the remote control and receiver module woks fine because to the receiver data pin, with a scope ,when I press one button to the remote control, I see the pulse train.
Below the Decoding sample code.

Code:
/*
  Simple example for receiving
 
  https://github.com/sui77/rc-switch/
*/

#include <RCSwitch.h>

RCSwitch mySwitch = RCSwitch();

void setup() {
  Serial.begin(115200);
  mySwitch.enableReceive(0);  // Receiver on interrupt 0 => that is pin #2
}

void loop() {
  if (mySwitch.available()) {
   
    Serial.print("Received ");
    Serial.print( mySwitch.getReceivedValue() );
    Serial.print(" / ");
    Serial.print( mySwitch.getReceivedBitlength() );
    Serial.print("bit ");
    Serial.print("Protocol: ");
    Serial.println( mySwitch.getReceivedProtocol() );

    mySwitch.resetAvailable();
  }
}
 
What can I do to see to the serial monitor, the remote control codes ?
