DHT22 support #5

Open iLLiac4 opened 9 months ago

iLLiac4 commented 9 months ago

Hi. Would it be possible to add DHT22 support? And also yearly usage.

I have few other questions:

  1. What happens if wifi is lost?
  2. Is there a reset button to zero it? Similar to this one https://github.com/oh2mp/esp32_energymeter ? TNX

Hello iLLiac4,

  1. if wifi is not available on start-up , the SW will wait until can connect. /Wait for connection/ while (WiFi.status() != WL_CONNECTED) { delay(500);

    ifdef DEBUG

    Serial.print(".");

    endif

    } 1.1 on mqtt loss, the system waits 3s than tryes to reconnect on wifi + mqtt

    /reconect on Mqtt loss/ if (client.state()< 0) {

    ifdef DEBUG

    Serial.println("No MQTT Connection, reconnect");

    endif

    delay (3000); setup(); ...

  2. there is no physical reset button, if is the case I just plug out the USB cable than reconnect it. But...the mqtt commands can be used to do this automatically (in home-assistant you can link it to automation).

                          "Additionally the following mqtt commands can be used:
                      - topic: /pulseenergymonitor/cmd
                      - payload: c / r
                        c - clear kWh information
                        r - reset the device"

DHT22 seams to be possible trough the DHT library, unfortunately I do have such a sensor, therefore, I would not be able to test it. Would it be great if you could implement it on a fork, then merge it with this. Yearly usage was on in my plan, I need to analyze if it would be possible to add.

Regards.
