Bests & Worsts Reviews from Amazon

I purchased a tempstick 7 months ago now to use to monitor the interior temperature of my motorhome. A big problem for motorhome owners and RV owners who travel with animals (2 cats in my case) is the possibility that the RV will lose power over the course of a day while the owners are off doing a day trip or other activity in very hot or cold climates. We are often in areas were we have to air condition to keep the coach reasonable while we take a day trip, and it has always been a concern that the power may fail and the temperature soar. So, this seemed like the answer. We have a MIFI Verizon cellular jetpack in the coach and we connect the tempstick to the MIFI and monitor the coach remotely through an iPhone app and website. Also, the way that this unit works is that it communicates temperature and humidity data with a server at IdealScience's location where the data is logged. You can then program into the IdealScience web page that you want to set a temperature limit of lets say 85 degrees and you want messages or emails to be sent to as many email accounts as you want when the temperature exceeds 85 degrees. This works great. If you get no messages, you know things are good. If you want to know what it is recording, you can log into your account and view the temperature and humidity data as far back as you want. Also, you can specify how frequently you want the temp stick to report data. It is battery operated so the more frequently you report, the faster you use your battery, but a set of batteries reporting hourly will work for many weeks. I have had only one problem and it stumped me and the owner of the company for hours was that we were parked in Tucson and the tempstick would keep "falling off" my MIFI (not stay connected). We tried everything but it just would not stay connected. I noticed that the RV park we were in had what appeared to be a short cell tower right in the middle of the park and maybe 100' from my coach. So I took the tempstick operating on battery into the car and out into a rural area with the MIFI and it connected immediately and stayed connected. What that told me is that there was a very strong rf field near that cell tower that was over-riding the transmitter of the tempstick or the receiver of the MIFI and knocking out the communication between the path. It was a real mystery to be solved. Since that, it has worked perfectly. I am now going to buy two more tempsticks which can be added to my account at IdealScientific.... one for the house that we leave when we travel (in winter, concerns about proper heat in the house) and a second house we have for storage. I am very impressed with the unit, and more impressed with the customer service. The owner spent hours with me on the phone trying to figure out what was going on.
