NFC tags are a complete game changer!! (self.homeassistant)

  • 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 think the best use case I’ve seen for nfc tags are periodic reminder reset. Place a nfc tag near your filter register then when you change your hvac filter, scanning the tag records the date which can then be used to send notifications when it’s time to change the filters again.

I do this and even have a card on my tablet/dashboard with how many days left on the filter! Tag is down on the furnace.

You just reminded me that I had tags on my furnace and under sink water filter. I never set them up again after I moved a few years ago.

I hear a weekend project brewing :)

That's an amazing idea, thanks! I have a stack of NFC stickers doing nothing at the moment
