check_json_temp.py

Check temperature, humidity, dewpoint provided by a sht11 temperature and humidity sensor from ¹ powered by an ATmega from ² on a json web page. I bought and assembled this system in 2007 and it is still working!

{
      "Sensor": {
            "SensorID": "192.168.100.19",
            "Temperatur": "25.7°C",
            "Feuchtigkeit": "55%",
            "Taupunkt": "15.0°C"
      }
}

Example:

/usr/local/bin/check_json_temp.py -H <IP> -sensor 0 -w 30 -c 40 -temperature -humidity -dewpoint
OK: Temperature: 25.7 C|Temperature=25.7;30;40 Humidity=55.0 DewPoint=15.0
