I had a chance to review a Belkin product a while ago with the WeMo LED Lighting Set, and I have just had a chance to review the WeMo Insight Switch. As you can see, it is a literal plug-in that you just plug in to an outlet.
From there, you can just plug in an appliance and monitor it from anywhere with the help of a customized application. You can turn devices on or off, program customized notifications and change the device status, provided your tablet or smartphone is getting some bars. It is good for space heaters, TVs, washers, dryers, and anything else you can plug in.
There is a lot of versatility with this particular device as it will show you a laundry cycle, and it will even monitor your energy usage. If you want to reduce your electric bill, turn off the device from a distance. By the way, this WeMo collection is modular with other WeMo products.
If you want to try this out, feel free to head on over to the Belkin site and lay down $59.99 for it.
