Sonoff-POW

Library and First Project for Sonoff POW switch The included libary is an enhanced version of the ITEAD.cc library

The library and the sketch reads the values from the Sonoff POW HLW8012 chip and calculates the respective Power, current, and oltage values. Only voltage or current reading can be chosen.

The sketch connects to the iopappstory.com and loads the assigned firmware down. It also asks for the WiFi credentials. and it connects to Adafruit.io as an MQTT broker. Pleas include the credentials in the credentials.h file and place this file in the libraries folder

The explanation of the project is on YouTube:

[idea] Sonoff POW power as separate library

Did you consider separating Sonoff_POW-master to its own project?
Separated library could be published to platform.io library registry (http://platformio.org/lib) and then included in projects as a dependency. An example of including libs as dependencies https://github.com/michalbogacz/flower-irrigator/blob/master/platformio.ini .

Benefits for users:

• no copy paste code
• possible version managing

ESP8266 - Sonoff POW - Reading HLW8012 and Webclient = Exception (0)

Hello,
I am using your library and it is working very good, however from time to time I get an Exception and the sonoff reboots.

I have implemented a simple sketch which reads the power values and sends them using a webclient. The webclient parts works perfectly without the POWER code so I presume it might be related to an interrupt.

This is the stack error shown in the serial monitor...

The reboot always happens in this code:

 Serial.print("connecting to ");
  Serial.print(host);
  
  // Use WiFiClient class to create TCP connections
   WiFiClient client;
  // const int httpPort = 80;
  if (!client.connect(host, httpPort)) {
    Serial.println("....connection failed");
    return;
  }
  Serial.println("....connected!");

I can see in the serial port the "connecting to host" message, but not the "connected.

Is there any chance the library is doing something during the "client.connect" which causes the exception:

EXCCAUSE Code	Cause Name	Cause Description	Required Option	EXCVADDR Loaded

thank you for your help

Set Param ?

Dear,

    this->power_param = {12.286,0};
    this->current_param = {14.818,0};
    this->voltage_param = {0.435,0};

I don't understand. how do caculator the parameter ?
Thanks!

Send Energy value increment between mqtt messages

I am saving the information received via mqtt into a MySQL database. If I store the energy value but the sonoff reboots I loose information as it starts back from zero. If an incremental value is send between mqtt messages then a simple SUM of rows would report the energy consumed during that period.
Is this possible?

Error in power_arduino.ino

Hey. On line 12 there is an error power_dev.selectMeasureCurrentOrValtage (VOLTAGE); In the word valtage. I found and corrected it, but still no indication of current. Although the voltage and power values are present ...

crashes on Sonoff POW v2

Guten Tag Herr Spiess
Vielen Dank für Ihre Bibliothek, die bald zwei Jahre klaglos ihren Dienst tut in meinen Sonoff POW v2 devices.
Mit neu kompiliertem Code funktioniert es leider nicht mehr. Der ESP Chip crasht sofort beim Aufruf einer Messung.
Ich bin nicht gut genug, das genauer zu analysieren.
Die Alternative Bibliothek von Xose Perez liefert zwar die Leistung (perfekt 25W bei einer alten 25Watt Birne), aber der Strom ist immer 0, auch wenn ich mich an seinen Beispiel-Code halte. Also auch nicht viel besser.

Haben Sie die Zeit, das Problem zu analysieren?
Wenn es nicht reproduzierbar ist, dann werde ich versuchen, einen minimalen Sketch zu bauen und den Crashdump zu analysieren.
