The next obvious step is clearly to add an easy, non-getting-your-phone-out-and-tapping-at-it channel to respond to the coffee offer. Fortunately Belkin also make a WeMo motion sensor and they've integrated their devices with If This Then That. Which was clever of them.
Which means all Anne has to do, if she fancies a coffee, is wave her hand over that little carboard tube and I get a text message demanding caffination.
(The tube has the motion sensor in it, it was added to prevent false positives. Obviously when this sort of thing is in Target or Habitat they'll get Zaha Hadid to do a better job of the hardware than cardboard and duct tape. But you get the idea.)
The next step is a negotation over whether the motion sensor should be right next to the bed, so no getting up is required. Tricky.
