I was doing some electrical work on the lights in our guest bedroom this morning, and wanted to turn the power off at the fuse box before I did so.
However, we have a lot of circuit breakers, and, though I have most of them carefully labelled, the three controlling the upstairs lights were not among them. So I was expecting to do a fair bit of running up and down stairs to see whether the one I had switched off did in fact control that particular light.
“There must be a technological solution to make this less energetic!”, I thought… and then remembered that my Apple Watch has the ‘Camera Remote’ app, which can give you a remote viewfinder for your phone’s camera. So I put the phone on the bed pointing up at the light, trotted downstairs, and flipped switches until my watch showed that the light had switched off. Perfect!
(I was feeling very pleased with myself for this solution, and only rather later did I remember that, since all the lights in the house are under the control of my Home Automation system anyway, I could simply have looked at that to see when the light had gone offline! But perhaps that wouldn’t have happened quite so instantly.)
