Many folks assume that they need to have a Moto 360 or Apple Watch to control their home electronics. It is possible to use a Pebble watch for that. This video by Gerrit K-Meier shows how you can use Fhem, Simply.js, and a smartphone to do the job. For those of you not familiar with Fhem, it is a GPL’d Perl server for home automation.
As you can see in the above video, it is possible to switch a lamp on/off using a Pebble smartwatch. Of course, you can do a whole lot more if you are creative enough.
