Product review (4 stars): Convenient Indoor/outdoor temp/humidity monitor. Works great!
This is ideal for monitoring the temp and humidity of my greenhouse as well as our well pump house. I like that we can set an alarm so if our well house temp drops to below freezing we are alerted and can act to prevent the pump freezing.  Plus the well house is over 100 feet from the unit base but our wifi signal is still strong so the unit in the well house displays just fine.
