NFC tags are a complete game changer!! (lemmy.world)

I have no garage door opener so I added a tag in my car to open the smart garage without having to open the app and fiddle with things.
I added a tag to our light switch that turns on our bedroom lamp (softer, more pleasant light at night).
I added a door tag to unlock the door (no information contained on the tag so nobody can break in).
I added a tag that pauses an automation at night so my stair lights don't come on with motion sensing.

This is literally just the tip of the iceberg. I think of a new one every couple hours. Anyone have any other cool ones to share?

I liked nfc for that as well but then realized anyone that finds it can just overwrite your tags. No one can overwrite my bluetooth beacons.

With iPhone shortcuts, you don’t actually read anything off the tag, it just recognizes it and runs a shortcut that calls a home assistant entity (least that’s how I do it).

Your NFC reader on your phone reads the data on the tag whether you believe it or not. If you have writeable tags, someone can just overwrite your tag rendering it useless to you until you fix it.

Are you really that worried about someone overwriting your tags?

There’s no one in my family or friends that would even realize they’re writable, let alone actually figure out how to do it.

I have an NFC tag which has a homeassistant action written to it, and it’s also set up in Shortcuts as an automation. It works on Android, and iOS! So no, you can’t override the shortcuts trigger.
