wmr 968, For those who are using this weather station, i would like your opinion on it. Also is it true this station will only record temps down to -4 F only?? i have a coworker looking for a basic one with pc access to have at home and doesnt want to pay the price for a davis.
I’m happy with my 928 (the UK model), and consider the build quality to be superior to that of the more recent WMR200. Another advantage of the 928 (and I assume 968) over the 200 is that the 928 has separate solar panels for wind, rain and outdoor temp, and all have nice long long leads between the sensors and the solar panels.
The manual does quote -4F (-20 C) as the minimum for the outdoor temp sensor.
You might like to look at these manuals:

The first is the Oregon Scientific, the second is a much better one that apparently goes with a Radio Shack branded equivalent to the 968.
Thanks.
I also have a 968. Setup was very easy with the seperate solar panels for EACH sensor. That way, you can put them where they work the best. I have had NO trouble at all from it. When I set it up, I was pleasantly surprized that it located and read 3 extra sensors that I had purchased for a cheap temp/humidity station previously. It works extremely well with the Weather Display software as well.
Hi
I have been using Oregon Scientific Wireless Model WMR928NX
for some time now, I find the sensors to be very accurate
it is important to check and calibrate your sensors, I calibrate once a year
The only sensor I have found that deteriorates is the humidity Sensor due to the nature of its electronic sensing aliment
I would not be surprised if this also applies to the more expensive sensors as well
I have also converted several devices which can be added to your system
UV sensor
rain duration sensor
For your solar radiation sensor you can make a solar jar
Eventually I would probably upgrade to the latest Origen weather station but I would still use my modified UV sensor
and rain duration sensor,
the new station you can add more temperature sensors I would like to make a soil moisture sensor
wet leaf sensor ,
For more information on my station please have a look at www.weather-above.com

Anybody Knows how low does the Thermometer go? my lacrosse only goes to -21.8, which we almost surpassed this past winter. thanks for all the input.
I presume you realise that the WMR200 won’t read from WMR928 ‘extra’ sensors?
Have you considered making use of Meteohub with an RFXCOM receiver? The RFXCOM receiver can pickup up both WMR928 and WMR200 sensors and feed them to Meteohub which can in turn feed them to WD (see Meteohub displaying in WD).
At present my RFXCOM/Meteohub combination is collecting data from WMR200 anemometer, rain gauge and outdoor temp/hum, WMR928 anemometer, rain gauge, outdoor temp/hum, and indoor temp/hum/baro, and 3 WMR928 ‘extra’ sensors.
My Meteohub based copy of WD is processing data for all of those except the WMR200 anemometer, rain gauge (because, reasonably enough, WD only expects one anemometer and one rain gauge).
I haven’t yet tried doing so, but I believe that with the RFXCOM/Meteohub combination you can pick up data from more than the usual 3 WMR928 ‘extra’ sensors if required. For example I hope shortly to get another WMR928 extra temp sensor with the temp probe on a lead to use for soil temp, I don’t expect the WMR928 console to pick it up unless I take out one of the other extra sensors, but so far as I’m aware I should be able to have RFXCOM/Meteohub pick up that sensor in addition to the rest!
Maybe worth investigating?
With lithium AA back-up batteries the 968 should register down to about -40. The lowest I’ve registered was -35F, fortunately that’s as cold as it got while I had the 968.
As I recall the -4F spec was for using alkaline batteries. The specs for the batteries themselves are -4 for alkaline and -40 for lithium. I remember some people claimed to have registered considerably lower than -4 even with alkalines, though I think lithiums are worth it for cold climates, they last longer too.
I now have the 4th ‘extra sensor’ in place, and it is being read just fine by the RFXCOM/Meteohub combination. 
I did discover a problem getting WD to read temp only sensors from Meteohub, but I was I able to implement a cgi based workaround - you are welcome to details for the workaround if you are interested.
