Bests & Worsts Reviews from Amazon

Purchased the hub and 2 sensors. Setup was successful and everything worked fine for one day. Then... The sensors would sporadically disconnect and I could not reconnect them, despite following the website advice many, many times. I contacted customer support by email and followed their instructions to power down the hub. While this worked once, it did not work other times. I also removed the batteries from the sensors (no advice on the website regarding this), and this worked at least once. But how am I supposed to do these things when I am away from my house? (Even a "standard" reconnect requires you to push a button on the sensor.) The hub would also sporadically disconnect, even though is was close to the router. While it would reconnect about a half hour later a device would be disconnected with the same reconnect problems above. Customer support ("Ryan") was less than helpful. Their only advice was to repeat the obvious webpage instructions and to power down the hub. When I requested clarification they did not return my email. "On paper" this is an attractive system -- if it worked. But it simply did not work for me. Customer support by email was worthless. I strongly recommend an alternative system. (Note that this disconnecting is a common problem in these reviews. Also, as of my review almost 1/3 of the reviews are 1-star. In my experience with Amazon reviews, any product with this many 1-star reviews has SERIOUS problems.)
