Product review (5 stars): Works great, long battery life if setup well
I have been using for over a year now to keep track of the temp in on our baby's room and it works great.  I'm using it with the Indigo Server on a Mac Mini with a ZWave controller.  I've set the temperature polling to only send changes after 15 minutes, this gets great battery life and is good enough to reflect temp/humidity changes that occur in the room.
