TLDR: I have a non-cellular watch. Anyone have an idea how I can produce a trigger event using only some property of the watch with no network?
When I go for a run, I only have my watch, no iPhone. I can open my front door with Indigo via the phone (by SMS to Indigo that triggers a relay) but I'm trying to figure out how I can trigger an event (the door open) using only the non-cellular watch.
NFC is out because Apple doesn't give access. The front door is too far away to allow a bluetooth connection to the network. What else could be used on a watch with no network? That's the challenge!
