dht11- gethumidity， gettemperature data not upload yeelink

how modify code ？

code: [select]

void postvalue(int sensor, float value) {
  process p;

  p.runshellcommand("curl --request post --data '{\"timestamp\":\"'"
                    + string("`date '+%y-%m-%dt%t'`")
                    + "'\",\"value\":"
                    + value
                    + "}' --header \"u-apikey: xxxxxx\""
                    + " http://api.yeelink.net/v1.0/device/"
                    + deviceid
                    + "/sensor/"
                    + sensor
                    + "/datapoints");
}

i have 2 suggestions:

1) after calling p.runshellcommand() in postvalue, , display error message output process. it's hard debug problem if don't see error messages. example, line this:

code: [select]

 while (p.available())
    serial.print((char)p.read());

2) consider simplifying sketch, , doing command formatting (including getting date) in python. if write python script takes 2 parameters, sensor id , value, can test ssh command line. way, able try various data values, , directly see error messages. then, when know working, can call like:

code: [select]

  p.begin("/usr/bin/python");
  p.addparameter(sensor);
  p.addparameter(value);
  p.run()


actually, if writing this, i'd doing as possible in python. example, of commands in postpicture() easier in script on linux side, , call single script run it. consider putting of in single script, first parameter gives operation (post value, picture, or relay control) , additional parameters vary depending on operation: sensor/value post value, , nothing post picture , relay control. way, of remote system details , keys down in 1 python file. when write system this, keep sketch simple possible - make dumb i/o processor. find easier update , debug script on linux side, , linux side faster , more powerful, of work possible on processor.
