Weather station

The unit I have bought is Termometerfabriken Viking 02049--a clone of Fine Offset Electronics WS 2080 which in turn is a newer version of the well known WS 1080/1090 models. This weather station measures wind speed and direction, outside temperature and humidity, inside temperature and humidity, rainfall and barometric pressure. It is equipped with 4 outside sensors namely: a thermo-hygrometer (THS), a wind direction sensor, a wind speed sensor, and a rain gauge. Only the temperature and humidity sensor is equipped with radio transmitter unit, so wind & rainfall sensors are connected to THS with telephone cables.

I have decided not to follow mounting as described in the manual. I put THS inside my wooden Stevenson screen which I have built some time ago and which I consider much better than the plastic ersatz included with the station. A rainfall sensor is mounted nearby. A real problem is the wind sensors. I plan to buy 30 m extension cable (original cable is only 2,5 m long) and mount the sensor at the roof of my flat. Complicated, but there are no other viable alternatives :-)

The software included is of no use to me as well. Fortunately there are free alternatives: wview and pywws. I have started with the first one not being aware of pywws existence.

Wview installs w/o problems in Lenny:


apt-get install wview

but fails to work:


/etc/init.d/wview start
/etc/init.d/wview: line 57: 1934 Illegal instruction $WVIEWD_BIN

wvpmond[1942]: &1302287846942> : wviewd process not running - aborting!

Looking via Google how to proceed I have found nothing except the impression that wview is not finely maintained nor top quality software. Fortunately I have discovered pywws which installs and works flawlessly.
