What to do with a wemo switch?

I’ve had this WEMO switch for ages now, and I got it working doing things like switching on a light depending on twitter hashtags using IFTTT. That’s all fine, and quite good fun, but essentially not too useful. So I’ve been thinking about what I could use it for that would be a really good and useful application of the device.

So far, nothing. No ideas at all. Which is a shame as I think it’s a good idea and should have a use. I just haven’t found it as yet.
