Product review (2 stars): Great potential; awful handling of collected data
Installation was a breeze and the system is incredibly simple to use - great job. Temperature readings are right on the money most of the time, except when they stick and than they can be off by several degrees (perhaps a defective sensor), so you can never be confident in the data that you are collecting, if you care at all about precision. We have not had this long enough to comment on battery life.

The one thing that makes this device completely useless for our purposes, is that it the service erases all the 15 minute increment data collected during the past day at midnight Eastern. You still have your rolling hourly data, but only for the approximately 12 previous hours. After that you only have the daily highs and lows and that for only the past month.

We thought it would be obvious that if we collect this data, we actually want to keep it. Apparently this is not so obvious for people at AcuRite, because they don't even give you an opportunity to download the data - they just purge it. To be fair, a feature appears to exist that makes it possible to share your collected data with Weather Underground and this may be all that some people care about. That is not our use case.
