PyMeteostation 0.1.0

Pymeteostation is software made for controlling meteostation built of MLAB electronic modules (http://www.mlab.cz/) and sending measurements to Open Weather Map (http://openweathermap.org/).

Currently supported sensors are:

• SHT25v01A (Sensirion SHT25)
• ALTIMET01A (MPL3115A2)

Software dependencies

• Pymlab (>= 0.2, https://pypi.python.org/pypi/pymlab/)

How to

1. Install PyMeteostation:

   pip install PyMeteostation
   

2. Create an account on http://openweathermap.org/

3. Run:

   pymeteostation -g
   

   This wil generate basic configuration file named .pymeteostation in your home directory.

4. Fill the generated config file:

   • [Meteostation] section:

     Requiered options: username, password, uploadinterval (in seconds) and logpath (must be absolute path)

     If you use ALTIMET01A sensor you must fill altitude option too. (It is used for correcting pressure to sea level altitude.)

   • [I2C_Device] section:

     Enter I2C configuration. (example options: type, name, address, channel, children…)

     Usage of children option:

     children = sensor1;sensor2;
     

     The names in children option are names of sections defining the children devices.

     Sensors must have name option filled.

     Currently supported device types: i2chub, sht25, altimet01

   • [Translation_Into_POST] section:

     Into option, which you want to send, fill sensor name, from which will be gathered data, and sensor measurement ID (this is because some sensors return more than one measurement).

   Example:

   [Meteostation]
   username = user
   password = XXXXXX
   uploadinterval = 120
   logpath = /home/user/PyMeteostation-logs/
   stationname = Meteostation 01
   latitude = 0.0
   longtitude = 0.0
   altitude = 0.0
   
   [I2C_Device]
   type = i2chub
   address = 0x72
   children = barometer;hum_temp;
   
   [barometer]
   name = barometer
   type = altimet01
   channel = 0
   
   [hum_temp]
   name = hum_temp
   type = sht25
   channel = 1
   
   [Translation_Into_POST]
   wind_dir =
   wind_speed =
   wind_gust =
   temp = hum_temp;1;
   humidity = hum_temp;0;
   pressure = barometer;1;
   rain_1h =
   rain_24h =
   rain_today =
   snow =
   lum =
   radiation =
   dew_point =
   uv =
   

5. (optional) I recommend to run:

   pymetostation -n
   

   This will run PyMeteostation not as service, so you can check if are there any errors.

6. Run:

   pymeteostation start|stop|restart
   

   This will start PyMeteostation as service.
