It's a wifi outlet that connects through a Cradlepoint router (I bought an inexpensive used one) and a Verizon USB modem to a cloud. You can control the outlet from your iphone, for example. I am paying $20 per month for 1GB of data which is an overkill, but I was lazy to look for an MVNO and I also use it as a hotspot when needed. Since it's a no contract arrangement, you can stop using it any time. For example, in your case you can use it only during winter.
I do not like cloud solutions in general, but in this specific case it was the most economical and painless approach not requiring a full blown automation system, such as ISY.
