I started experimenting with NFC as simple physical triggers and was surprised how useful they can be in real life.

Not the obvious stuff like opening apps — but things like:

• silent alarm disarm when leaving home

• context-aware scenes (time + presence based)

• resetting maintenance counters

• tracking daily routines

It made me realize NFC works best not as a “command”, but as an intent signal that automation logic interprets.

Curious what weird / unexpected / clever uses people here came up with.
