Product review (5 stars): Easy install if you follow directions and avoid problems cited by reviewers
I received the bridge and sensor bundle and within less than an hour was able to connect to it with the app and from my desktop. I followed some of the suggestions from other reviewers to set the channel on each tower to a different channel (A,B or C). I also created my account at acu-link.com before receiving the item and deleted the factory shared bridge under "follow my friend's bridge".
I had to calibrate 2 of the towers by 1-3 degrees to my thermostats and it looks like it is updating within 5 minutes. I had some trouble connecting to the web site for about 15 minutes after I completed set up. After that, it wasn't an issue. I also tested the email alerts and it worked.
Since I have had this for only a day, I can't comment on the long-term reliability yet, but I wanted to comment on the install process.
The IOS app is pretty good, but the multi tower dashboard is limited to 5 items and it would be nice to have the ability to calibrate from the settings in the app (calibration seems to be only available at the web site).
