Mildly disappointing but still worth the price
Got it for Christmas. The initial setup for the unit and the remote sensor were easy but keep in mind that the relative pressure (corrected to the sea level) and humidity/dewpoint have to be calibrated. The pressure was easy -- I looked up some nearby stations on the Internet and set it to the same value. I am still wondering how to calibrate humidity. The instructions recommend getting some kit to measure the humidity accurately but that seems to beat the purpose of buying this weather station. The best thing I could come up with was to set it to 99% on a foggy evening (it did not seem to work too well) and trying to match the dewpoint (I think it is more stable than relative humidity) to nearby stations. The latter method seemed slightly better, but still gets the humidity ~20% off at times compared to the stations nearby. If anybody has a better idea please let me know. Some other issues: The most annoying "feature" is that I could not find how to reset all min and max values with a single button or, which would be even better, to set it to reset automatically at a specified time every day. As it is, the unit reports min/max since the last reset, even if it was days ago. You have to push about 40 buttons to reset all the min/max values one by one. I also don't like the fancy flashing pressure history display. You may have to wait a few seconds to see the history for the whole 24 hours. As for the range of the remote (some people here were asking about it), it works fine for me across ~30' and three walls. The range reported for these things (as well as walkie-talkies etc.) assumes the receiver is in direct sight. Every wall or obstacle can cut the range quite a bit.
