Quiero preguntar si es posible conectar un Arduino nano directo a alguno de los pines de kc868 para comunicación serial

How to read pwm input with pcf8574 ?

Please help us create the integration of KC868-A16 into Home assistant via MQTT.
Home assistant does not see data from KC868-A16
   

Hello, i have a KC868-A8 Board connected with ethernet cable but the port suddenly stopped working.

# define ETH_ADDR        0
#define ETH_POWER_PIN  -1
#define ETH_MDC_PIN    23
#define ETH_MDIO_PIN  18
#define ETH_TYPE      ETH_PHY_LAN8720
#define ETH_CLK_MODE  ETH_CLOCK_GPIO17_OUT

IPAddress local_ip(192, 168, 0, 144);
IPAddress gateway(192, 168, 0, 254);
IPAddress subnet(255, 255, 255, 0);

  ETH.begin(ETH_TYPE, ETH_ADDR, ETH_MDC_PIN, ETH_MDIO_PIN, ETH_POWER_PIN, ETH_CLK_MODE);
  if (ETH.config(local_ip, gateway, subnet, dns, dns) == false) {
    Serial.println("EtherNet failed.");
  }else{Serial.println("EtherNet Success.");}

  Serial.println("Connected");
  Serial.print("IP Address:");
  Serial.println(ETH.localIP());
  delay(500);

I use a Mac, and do not have access to Windows PC

When powering on the A8 I hear the series of relay clicks and the power light is on.

I have connected USB C to C cable to my MacBook, but "ls /dev/cu.*" does not show any connected device and so I cannot flash firmware.

Any suggestions?

The AIO board Yaml file for Home Assistant creates "aio-Color-LED-1 to aio-Color-LED-16" outputs, and a single "aio-rgbw" output. How would these 17 different LED devices be connected to a AIO board? On the large AIO connection diagram I downloaded, you show a single LED strip connected to one of the two GPIO ports and a 1-wire humidity sensor connected to the other. Does another interface board need to be purchased and connected to the AIO board to control all these LED devices on the HA dashboard?

short disclaimer....I am new to this and trying to setup HA for automation as a DIYer [so I am not get all the terms correctly]

I recently recieved K868-server 16...following the instructions for installing HA image as suggested via youtube video https://www.youtube.com/watch?v=oEjIZg6C_-Y&t=486s

The problem is that I am not able to launch HA after installing the software on the SD card...the error I am getting is as follows [image attached]:

             [supervisor.jobs] ‘Updater.fetch_data’ blocked from execution, no supervisor internet connection 
             [supervisor.homeassistant.core] Error on Home Assistant installation. Retry in 30sec


I think i found the issue after reading through mulitple threads and I think the problem is the RPI local time not synchronizing with my local internet time hence it is not booting 

How to change the local time on the RPI…The problem is that i cannot type any command with my keyboard on this HA screen [2images attached]

Thank you for your help in advance

Hello,
i'd like to add temperature and umidity sensor to my kc868-A6 board.
The board is flashed with latest kincony firmware (2.2.4).

I know that this board has two specific input designed to accept temperature and humidity sensors.

I need some info:

1) wich sensors are suitable to this board?
2) wich one do you suggest?

Thanks

I have connected the SHT30 I2C sensor to the port and everything works for a few minutes like normal, and then I start getting errors and some warnings in the logs. I am using ESPHome. At the same time, one DS18B20 sensor also sends warnings, although it seems to work, but from time to time the sensor may become unavailable.

I also wanted to use the TCA9548A I2C Multiplexer to connect 3 SHT30/SHT40 sensors, but I also got errors. Nevertheless, all of these SHT30/SHT40 sensors work fine on the individual ESP32 boards.

CRC8 Checksum invalid at pos 0!
Component sht3xd.sensor set Warning flag: unspecified
Component dallas_temp.sensor set Warning flag: scratch pad checksum invalid

What could it be?
