Product review (2 stars): Great idea, nice interface, but too many things lacking to be truly useful
Received the unit, performed normal setup, and everything worked great initially. The web interface is pleasing, and you can set thresholds for temperature and humidity when it sends alarms. You also get alarms when the base unit cannot communicate with the remote sensor. But here are the problems:

1) I am using this for a place where there are power failures (think mid Michigan around Christmas), and expecting (and/or read in some reviews, I don't recall) that when communication between their web service and your base unit is lost, it sends alert emails. But not so! This function, which is really easy to implement on their end in the software, is missing! I purposely tried it a few days ago - nothing! I can see on the site directly when last communication occurred, but you'd really want email alert for that, just like for their other functions.

2) When I "restored the power failure" after perhaps 12 hours, it had lost the ability to synch to its probe. Now, several hours after the power restoration, the web site still shows "no communication". Of course you could now re-synch the probe and the base unit - but this is a major annoyance, because it takes time, but also because it never lets you know that power is indeed back! Not even on their web interface, considering the alarm doesn't work. And, more importantly: every home will likely go through a few power failures a year - do they seriously expect customers to re-do configuration of the unit after each one?

3) The "text" notification to the phone just did not work. The problem appears to be that they are not using a "true" text message, which may cost them money, but rather you select your provider and they apparently use the free "email to sms" service that most major provider offers. Well, I am one of the growing number of people who use cheap no-contract per minute plans (in my case PTel, 5c/min, and 10c/megabyte, on T-mobile network, works great and very cheap! Get it!) And these services offer regular sms, but no "email to sms" So out of luck there.

4) Considering their "power out" notification doesn't work, I hoped that at least I could put it on power backup using passive power over ethernet (PoE). In that way I could "see" an actual suspected power outage on their web site in the form of unusual temperature ranges, or get temperature alert emails when the then dead HVAC can't keep the place in range anymore. I have a centralized, high-power 12V backup system, including step-down to 9V / 5V, and with that you can power most "normal" internet things (routers, wifi, switches, internet cameras, etc). But - they use the oddest power transformer, it uses 20V (unnecessarily high for such a simple device requiring basically no power), and to top it all, it is AC (which for sure no common battery backup system provides). So they make it basically impossible to put their system on power backup, unless you plug it into a battery-powered 120V system - but these usually run only a few hours at most.

What is very annoying is that all these issues could have been solved/avoided for no extra cost (except perhaps the sms, which I even would be happy to pay on a per-case basis) if their design engineers had just thought things through a little longer. I surely hope they will get fixed in future upgrades. As it is right now, the unit is severely limited in its actual useability.
