Add support additional funcion on sensor SPS30

[tiimsvk]

Describe the problem you have/What new integration you would like Hello, could someone look at the other functions in the datasheet for the SPS30 dust particle sensor.

• enable sleep/idle mode
• switching on and off auto clean
• Fan speed warning
• Laser failure
• Fan failure
• UART support

These functions would help in diagnosing the fault if the sensor is installed in an inaccessible place. well thank you

Please describe your use case for this integration and alternatives you've tried:

Solution:

It is necessary to create an external component and define it in yaml:

external_components:
   - source: custom_component

Create the sps30 directory in the custom_component folder and copy the entire original sps30 integration into it

- automation.h
- sps30.cpp
- sps30.h
- __init__.py
- sensor.py

Further editing of files: sps30.h: after line 31 (bool start_fan_cleaning();) add the following:

   bool stop_measure();
   bool start_measure();

sps30.cpp: add the following at the end:

bool SPS30Component::start_measure() {
   uint8_t data[4];
   data[0] = SPS30_CMD_START_CONTINUOUS_MEASUREMENTS & 0xFF;
   data[1] = 0x03;
   data[2] = 0x00;
   data[3] = sht_crc_(0x03, 0x00);
   if (!this->write_command(SPS30_CMD_START_CONTINUOUS_MEASUREMENTS, SPS30_CMD_START_CONTINUOUS_MEASUREMENTS_ARG)) {
     ESP_LOGE(TAG, "Error initiating measurements");
     return false;
   }
   return true;
}

bool SPS30Component::stop_measure() {
   if (!write_command(SPS30_CMD_STOP_MEASUREMENTS)) {
     ESP_LOGD(TAG, "Stop measurement");
   }
   return true;
}

Subsequently, it is sufficient to invoke the action using the button template:

buttons:
   - platform: template
     name: "Stop measure"
     on_press:
       then:
         - lambda: id(my_sps30).stop_measure();

   - platform: template
     name: "Start measure"
     on_press:
       then:
         - lambda: id(my_sps30).start_measure();

There is one catch when you press stop, if you have set an update interval for some time, then every 5 sensor reading failures, the sensor is reset and continues measuring again.

This setting is defined in sps30.cpp

static const uint8_t MAX_SKIPPED_DATA_CYCLES_BEFORE_ERROR = 5;

why not merge this?
