Hello everybody!

I'm super happy with my Kincony so far. I don't have a lot of exp. and this is a reason why I would like to ask you here. 

My case: I have bistable relays - two tracks connect to my lights. Switch on the wall is a ring switch. Press and turn on light. Switch back to first position, but relay is set like ON. 
I would like to connect Kincony output/relay parallel to that wall switch. But I can not leave Kincony relay closed longer than 1 sec. Why? Because my Schneider relay will be hot after some minutes. 

Question: is it possible to configure the relay with a momentary switch action? 

Scenario: I click in the app and relay will turn on the light (same like wall switch). Next click on the wall or in the app will turn off the ligh. But question if Kincony will see the state of the light? 

Im guessing not out of the box. Because Schneider has two tracks, potentially I could check/probe a state of that in Ardiuno or even somehow in Kincony. 

What do you think? What could be the best solution for me?

Thank you for help!

We have designed 10 Channel ESP32 energy monitor board – N10 (ESP32 30 Channel CT Clamp Energy Monitor) for home automation project. It based on ESP32-S3-WROOM-1U (N16R8) wifi chip. The hardware have 10CH CT Clamp sensor INPUT ports + 1CH ZMPT101B voltage sensor + SD card + LoRa module + OLED display + free GPIOs. Ethernet+RS485+i2c extender 10CH high-accuracy energy meter ic-BL0910 with CT clamp. You can write any code by Arduino IDE / Micro Python / ESP-IDF development tool to ESP32-S3 module. We will supply Arduino demo code for different samples. Everyone can modify and change the code for your own smart home automation system project. it support use by ESPHome for home assistant for smart home automation DIY. N10 use KCS v3 firmware, it support home assistant auto discovery function by MQTT, so without write any config code (zero code) for home assistant. KCS v3 support KinCony cloud service (official shop customer free 2 years), remote monitor and control device by webpage in anywhere. KCS v3 support KinCony board integrate to Loxone Miniserver. Support Apple HomeKit for Siri.

Hi,
I have successfully set up the Kyncony KC-868 A4, and using Node-RED with HTTP requests I can now switch the relay. From here, it’s only a matter of programming the desired algorithm. 
But since the A4 has a limited number of analog inputs, we also got the KC-868 COLB. 

I have successfully upgraded the firmware of the COLB to the latest version using the guides from the forum.

When I use VirCom or IP Scanner software to search for the COLB device in the network, it doesn’t find any COLB. That’s why the SCB software doesn’t work either.

I connected the COLB via Ethernet cable to a switch that assigns IP addresses through DHCP. The laptop I am using is also connected to the same network.

Could you please tell me where I am making a mistake? Do you have a precise guide or step-by-step instructions on how to connect the COLB?

Additional questions:
– Is it possible to connect the COLB via WiFi as well? I am confused by your guides, it’s not clear to me. If yes please send me some guide how.
– How many DS18B20 digital sensors can be connected to a single channel? Only one?

Thank you very much for your assistence,
ALois

Hola a tothom,
Estic intentant establir una connexió I2C entre una placa Kincony KC868-A8 i un ESP32C3 . He implementat correctament la lògica del projecte i he verificat la configuració de la comunicació connectant dues plaques ESP32C3. Funcionen perfectament com a mestre i esclau, detectant-se mútuament i intercanviant dades sense cap problema. La meva configuració per a aquesta prova era una connexió directa pin a pin:

• Pin 20 (SDA) a Pin 20 (SDA)
  
• Pin 21 (SCL) a Pin 21 (SCL)
  
• GND a GND
  
• 5V a 5V
  

• KC868-A8 Pin 4 (SDA) i ESP32C3 Pin 20 (SDA)
  
• KC868-A8 Pin 5 (SCL) i ESP32C3 Pin 21 (SCL)
  
• GND a GND
  

Dear Admin,

Could you please confirm if it is possible to install Ubuntu on the Raspberry Pi Compute Module 5 IoT Server? Your assistance with this inquiry is greatly appreciated.

Best regards,

Subject: Request: Sequential 8-relay example for F8 (ESP32-S3), 1.5s step, reverse on shutdown

Hello KinCony team,

I am using the KinCony F8 (ESP32-S3) board with the PCF8575 I/O expander to control 8 relays. I would like to have an Arduino example that performs the following:
  •  Sequential ON: Relay1 → Relay8, with 1.5 seconds delay between each relay.
  •  Sequential OFF: Relay8 → Relay1, with the same 1.5 seconds delay.
  •  Arduino IDE, using I2C with SDA = GPIO8, SCL = GPIO18, and PCF8575 address = 0x24 (please confirm).

My questions are:
1. What is the exact GPIO mapping for each relay on the F8 hardware revision?
2. Do you have an official Arduino example implementing this sequence?
3. If there is a recommended library or header file for this board, could you please share the link?

Here is a sample code I tested so far (for reference):
#include <Wire.h>
#include <PCF8575.h>

#define I2C_SDA 8
#define I2C_SCL 18
#define PCF8575_ADDR 0x24

PCF8575 pcf(PCF8575_ADDR);
const uint8_t RELAY_PINS[8] = {P0, P1, P2, P3, P4, P5, P6, P7};

void setup() {
  Serial.begin(115200);
  if (!pcf.begin(I2C_SDA, I2C_SCL)) {
    Serial.println("PCF8575 not found!");
    while (1);
  }
  for (int i = 0; i < 8; i++) {
    pcf.write(RELAY_PINS[i], HIGH);  // OFF at start
  }
}

void loop() {
  // Sequential ON
  for (int i = 0; i < 8; i++) {
    Serial.print("Relay ON: "); Serial.println(i+1);
    pcf.write(RELAY_PINS[i], LOW);
    delay(1500);
  }

  // Sequential OFF
  for (int i = 7; i >= 0; i--) {
    Serial.print("Relay OFF: "); Serial.println(i+1);
    pcf.write(RELAY_PINS[i], HIGH);
    delay(1500);
  }
}

Hi,

I've been looking into using a DIN +12V DC power source for the KC868-A8, and I noticed that the new KC868-A6v3 is advertised with the comment: "new protection circuit to prevent power polarity from burning out."

This got me thinking—what would happen if I accidentally reversed the polarity on the KC868-A8?
Would it burn out immediately? Would it simply not work?
Does the KC868-A8 have any protection against this kind of mistake?

Thanks

Hello

Is it possible to power (VCC) from a GPIO output? I need to be able to reset a DS18B20 by turning off the VCC to the sensor as they get out of timing sync often and only are able to re-sync from a power cycle - not from a node reset.

Whats the max current the GPIO as an output that ic an supply

Hi All,

I’m after some advice on what to buy. I’d like Home Assistant to trigger a Finder DIN-rail power relay with a 12 V DC coil ( 22.23.9.012.4000 | Finder DIN Rail Power Relay, 12V dc Coil, 20A Switching Current, SPST-NC, SPST-NO | RS ) whenever I have excess solar during the day. 

The relay will switch a hot-water system. Which KinCony device would be the best fit, and can this finder relay coil run on AC as well as DC?

Here is the data sheet  0900766b816bcd62.pdf

   
 
Thanks!
