Revision as of 09:53, 20 April 2013
Web server of Meteobridge client, which presents web interface for adminstration to you, can also deliver weather data. There are two URLs defined that can be polled to get most recent sensor data in XML or plain text. Although we don't recommend this for security reasons, you can make that URLs accessible from the Internet by configuring your router appropriately. However, when you want to bring sensor data to one of your own servers in the Internet we recommend to make use of Meteobridge's Push Services, which will not need you to open up your firewall.
Live Data as XML
By sending the meteobridge a HTTP request like "http://ip-of-meteobridge/cgi-bin/livedataxml.cgi" (where "ip-of-meteobridge" must be replaced by the IP itself) meteobridge returns current weather data in XML notation. Each reply starts witch tag <logger> and ends with </logger> with the sensor data as records with sensor specific tags "THB", "TH", "WIND", "RAIN", "UV", "SOLAR". Example below illustrates the XML format:
<logger>
<THB date="20121227224318" id="thb0" temp="26.0" hum="37" dew="10.2"
press="1008.8" seapress="1010.1" fc="2"/>
<TH date="20130104141909" id="th0" temp="9.1" hum="95" dew="8.3"/>
<RAIN date="20130104141856" id="rain0" rate="0.0" total="3.0" delta="0.0"/>
<WIND date="20130104141916" id="wind0" dir="109" gust="0.9" wind="2.2" chill="9.1"/>
</logger>
Each sensor data record has a mandatory "date" and "id" parameter. The other parameters are sensor specific. Meaning of parameters is:
- date: UTC timestamp of reception of sensor data in format "YYYYMMDDhhmmss"
- id: Unique ID of sensor, consists of a sensor type description shortcut followed by a number, which is always "0" in Meteobridge, as additional sensors are not supported
- temp: temperature in degrees Celsius (with one decimal)
- hum: relative humidity in percent (no decimals)
- dew: dew point temperature in degrees Celsius (with one decimal)
- press: station pressure (without altitude correction) in hPa (with one decimal)
- seapress: normalized pressure with altitude correction (also called sea level pressure) in hPa (with one decimal)
- fc: stations forecast code, if provided. As this has low evidence and also largely varies between stations, meteobridge does not recommend to make use of this data.
- rate: measured rain rate in mm per hour (with one decimal).
- total: current value of rain bucket counter, converted to mm (with one decimal).
- delta: additional rain fall in mm since previous readout of this data (with one decimal).
- wind: current average wind speed im m/s (with one decimal).
- gust: curent not avergaed wind speed in m/s (with one decimal).
- dir: wind direction in degrees (0-359, no decimals).
- chill: wind chill temperature in degrees Celsius (with one decimal).

Live Data as Plain Text
By sending the meteobridge a HTTP request like "http://ip-of-meteobridge/cgi-bin/livedata.cgi" (where "ip-of-meteobridge" must be replaced by the IP itself) meteobridge returns current weather data as plain text. Each reply consists of a series of lines, where each line represnets a sensor. Lines do start with a time stamp and a unique sensor id followed by sensor specific parameters. Example below illustrates the format:
20130104142614 thb0 26.9 38 11.4 1020.4 1021.7 2 20130104142610 rain0 0.0 3.0 0.0 20130104142636 th0 9.1 95 8.3 20130104142652 wind0 160 2.2 1.8 8.0
Data via Socket Connection
Methods introduced above do need HTTP authentification like all elements of Meteobridge web interface. A look at the script "livedataxml.cgi" shows that this just reads data from socket 5557, gives it a suitable HTTP header and returns that to the requesting browser:
#!/bin/sh echo -ne "Content-type: text/xml; charset=UTF-8\n\n" nc 127.0.0.1 5557 2>/dev/null
Therefore, reading data from socket 5557 is equivalent to calling "livedataxml.cgi" and socket 5556 reports same data as delivered by "livedata.cgi".
