iHome devices are configurable along with Hue and Wemo to use in groups and scenes. This works perfectly with my iHome outlets. I currently have 3 iHome iSP6 SmartPlugs, purchased from Wal-Mart, Amazon, Best Buy.

It seems reasonable to think that the setup which works for these should work for all other similar iHome SmartPlugs. If anyone owns some other kind of iHome SmartPlug and is having issues, create a thread in the Support forum and I will help you out.
