ESP82266 + Arduino IOT Cloud problem

Using Arduino Programming Questions
1

Hello.

I have made two projects with ESP8266 and Arduino IOT Cloud.

First project is to control a relay based on soil moisture data.
Second project is to control a relay based on temperature.

I have written the code for these projects and i have connected devices but my problem is that i cant read data from sensors and i cant control relay from the Arduino IOT Cloud.

Can anyone help me to solve this problem?

Regards,
Fatmir.

There may be someone here that can help you solve your issue but you would do well with helping those who would help you.

Pick one of the 2 projects.

Post the code in code tags like so:

void fUART_try( void * pvPrameters )
{
int BUF_SIZE = 1024;

  uart_config_t uart_config = {};
  uart_config.baud_rate = 38400;
  uart_config.data_bits = UART_DATA_8_BITS;
  uart_config.parity    = UART_PARITY_DISABLE;
  uart_config.stop_bits = UART_STOP_BITS_1;
  uart_config.flow_ctrl = UART_HW_FLOWCTRL_DISABLE;
  //uart_config.source_clk = UART_SCLK_DEFAULT;
  //int intr_alloc_flags = ESP_INTR_FLAG_IRAM;
  uart_driver_install( UART_NUM_1, BUF_SIZE * 2, 0, 0, NULL, ESP_INTR_FLAG_IRAM );
  //uart_driver_install( UART_NUM_1, BUF_SIZE * 2, 0, 0, NULL, intr_alloc_flags );
  uart_param_config( UART_NUM_1, &uart_config);
  uart_set_pin( UART_NUM_1, GPIO_NUM_17, GPIO_NUM_16, -1, -1 );
//reset the VCO76
uint8_t args[] = {0x0};
//runCommand(VC0706_RESET, args, 1, 5, 1)


  for (;;)
  {

  }
  vTaskDelete( NULL );
}

Next post a schematic.

Next post images of your project.

  Arduino IoT Cloud Variables description

  The following variables are automatically generated and updated when changes are made to the Thing

  CloudTemperatureSensor temperatura1;
  CloudTemperatureSensor temperatura2;
  bool rele;

  Variables which are marked as READ/WRITE in the Cloud Thing will also have functions
  which are called when their values are changed from the Dashboard.
  These functions are generated with the Thing and added at the end of this sketch.

@Idahowalker Can you help me with project first, please ?

When you ran the example program for the DHT, did it work? How does your use of the DHT library differ from the example program?

Why not instantiate the dht objects?

Which DHT are you using?

5

@Idahowalker Can you help me to monitor temperature and humidity ?
I have tried many times but its not working.

6

You tried the dht examples and they do not work? I'd say your DHT sensors are not properly wired up.

7

@Idahowalker The Arduino agent icon is always grey. I think this is the problem. How to solve this problem, can you help me ?

8

@Idahowalker Its my first project with Arduino IOT Cloud. Can you help me to finish this project please ?

9

Did you ever get the DHT working by itself?

10

Yes. When i use ESP8266 and DHT sensor, without Arduino IOT Cloud, its working. But when i try to connect to Arduino IOT Cloud its not working.

11

So the DHT sensor is not being read when you connect to the IoT thingy? Have you connected to the IoT thingy without the DHT?

12

@Idahowalker No i havent connected the ESP8266 without DHT. How to do that ?

13

I'm sorry I do not have the knowledge to help you.
