I purchased a board on aliexpress with the identical PCB layout as the kincony A6 board. 

What's the story behind this board? Is it made by kincony?

xxxxxxxxxxx

I plugged it in and it started smoking, lol.

Hi

The instructions says 12 V DC input power. OK - but if used in a boat or car the battery voltage can be somewhere between 11 anf 15 volts...

Is that ok for the 868-A6 unit?


Regards
TT

Good day,

I have a KC868-A8 with firmware version 2.2.6 and when I log into the web interface and click on some of the menu items I get taken back to the login screen. This happens randomly with the menu items.

I am waiting for the kc868-A16 to be delivered. My goal is to make a complete program in Arduino to support my own smart elements - the superior system is Domoticz/HomeAssistant. Are there any examples in Arduino that show how to implement access to all PCF and other in/out ports (pins, addresses) as well as the LAN module (pins, addresses) in the Arduino environment? If so, where can I find them. I know that you can do reverse engineering and laboriously check and test everything - but if someone has already figured it out - maybe they could share a few source files.

Is B16M coming with some preloaded firmware? Which one is it? Is there a ready to use KCS firmware for it, similar to things like KC868-A16, if yes, where it can be found?

Hello  

Setup:     
M30 AC energy meter connected to Home-assistant server running in virtual machine with windows host, the M30 connected to pc through onboard USB debugging port and RS485 to USB converter (COM 3 & COM 4) and connected to same network as pc through Ethernet

Problem: 
-- the Home Assistant frontend dashboard shows the board current readings: m30_1,2,3_current_1--10  = 0.357 A , Watt: 140.3W,  4,771.0 kWh,  5,141.0 kWh,  tps_1,2,3 = 4,574.6 °C
the CT sensors is not connected to any active load ?  
--  when connect the CT sensors to load the reading did not change ?
-- Connecting  modbus pull with same configuration as in yaml file { uart:   id: modbus_uart  rx_pin: 32  tx_pin: 33  baud_rate: 115200  stop_bits: 1  data_bits:   parity: NONE}   it shows timeout error with no readings? 

Required: 
-- How to reset the CT sensors current readings and energy reading to Zero when there is no loads or the sensors not connected, remove the un wanted history and start fresh. please show example of any modifications needed in yaml file. all sensors are brand new and never used before.
-- Why there is no reading when i connect the CT sensor to an active load ? did i mess something? 
--  Why i cant read the sensors trough modbus pull from register 3 ? how to fix timeout error ?
-- Noticed when using the yamal file posted that we can not use Ethernet and WIFI at the same time? why?
-- I tried with another M30 board the current reading 0.220 A watt zero but also the reading did not change when i connect the CT sensor to active load? any reason?
-- why TPS shows very high readings? what does it means?
-- Period readings = 457.8 Hz  ? can you explains? -not realistic readings-

Note: Attached the yaml used in the configuration, the dashboard for home assistant before and after connecting the CT to load, the modbus error

v3.0.3 improvement:

1. Fix the problem that mqtt custom port does not take effect
2. Fix the problem of missing comma separator when mqtt returns json
3. Fix the problem that the mqtt command does not support the simultaneous processing of multiple commands
4. Fixed mqtt instructions run_rf, run_ir, set_beep returning wrong json format

Here is "KCS" firmware for KinCony KC868-A series (ESP32) board.
How to download and use, online guide: https://www.kincony.com/esp32-kcsv2-firmware.html

v2.2.7 improvement:
1. Fix the problem that the mqtt command does not support the simultaneous processing of multiple commands
2. Fixed mqtt instructions run_rf, run_ir, set_beep returning wrong json format

for example:

{"output1":{"value":true},"dac1":{"value":250}}
   
   

{"output1":{"value":true},"output2":{"value":false},"output3":{"value":true},"output4":{"value":false},"dac1":{"value":125}}
   
   

these can write in one payload.

Salve,ho comprato questa scheda.
Ho installato il firmware tasmota e funziona ingressi e uscite.
Volevo chiedervi se è possibile avere il codice per farla comunicare da PC rs232 o con USB tramite comandi seriali.
Esempio:

Rs232 relè1on invio
E avere tutti gli stati  input  sempre in via seriale 
In modo tale da visualizzarlo con visual basic.
Grazie

I am new here... I have uploaded the digital input code to the KC868-a8s-v2 from the knowledge base. SEE BELOW. When I test the voltage on the input with nothing connected, there is 11.2v read from all of the inputs. 

Why is this happening? 

How do I use the digital inputs? 

#include "Arduino.h"
#include "PCF8574.h"

// Set i2c address
PCF8574 pcf8574(0x22,4,5);// 0x22 is address, IO4 is SDA  IO5 is SCL
unsigned long timeElapsed;
void setup()
{
    Serial.begin(115200);
    delay(1000);

//    pcf8574.pinMode(P0, OUTPUT);
pcf8574.pinMode(P0, INPUT);
pcf8574.pinMode(P1, INPUT);
pcf8574.pinMode(P2, INPUT);
pcf8574.pinMode(P3, INPUT);
pcf8574.pinMode(P4, INPUT);
pcf8574.pinMode(P5, INPUT);
pcf8574.pinMode(P6, INPUT);
pcf8574.pinMode(P7, INPUT);

    Serial.print("Init pcf8574...");
    if (pcf8574.begin()){
        Serial.println("OK");
    }else{
        Serial.println("KO");
    }
}

void loop()
{
uint8_t val1 = pcf8574.digitalRead(P0);
uint8_t val2 = pcf8574.digitalRead(P1);
uint8_t val3 = pcf8574.digitalRead(P2);
uint8_t val4 = pcf8574.digitalRead(P3);
uint8_t val5 = pcf8574.digitalRead(P4);
uint8_t val6 = pcf8574.digitalRead(P5);
uint8_t val7 = pcf8574.digitalRead(P6);
uint8_t val8 = pcf8574.digitalRead(P7);
if (val1==LOW) Serial.println("KEY1 PRESSED");
if (val2==LOW) Serial.println("KEY2 PRESSED");
if (val3==LOW) Serial.println("KEY3 PRESSED");
if (val4==LOW) Serial.println("KEY4 PRESSED");
if (val5==LOW) Serial.println("KEY5 PRESSED");
if (val6==LOW) Serial.println("KEY6 PRESSED");
if (val7==LOW) Serial.println("KEY7 PRESSED");
if (val8==LOW) Serial.println("KEY8 PRESSED");
    delay(300);
}
