NFC tags are cheap and fun
Actually NFC tags were one of my first things back when I was using HomeKit. They are much better in HA because you can fire an event without any interaction with the device that scans it and that is pretty cool.
Thanks, I have a 10-pack of tags that I could deploy to do random stuff for my own enjoyment. I appreciate the reminder!
The only downside is that the smartphone needs to be unlocked ๐
Not if you build an NFC tag reader! Then anyone can scan tags! Great for music jukeboxes!
Do you mean that smartphones can act as a NFC tag? Even when they're locked?
Oh sorry, I meant that with an nfc tag reader you donโt need the smart phone. Apologies that I wasnโt clear.
Oh, nooouuuu! I was so happy when I read your post! ๐ Thanks for clarifying.
You don't need to unlock your phone to fire an event in HomeAssistant. My iPhone needs to be awake but will still scan and run shortcut while locked.
In Android NFC doesn't work when the device is locked ๐ That's strange that it does on iPhones, usually is the other way around! ๐
Ooh, Ive heard of these. Can you name some of the ways you use them? Do these effectively work as a cheap alternative to a physical switch or can they be used more creatively?
Yeah it's essentially a trigger. I have a few purposes. One is for my dumb washing machine plugged into an energy monitoring smart plug. After it registers the washing is done, I'll get alerts through the house in intervals until I get up and scan the NFC tag on the washing machine (I forget to hang out washing.
As I'm in a rental and I can't have smart switches so I have smart globes and put tags on the switches to toggle the lights.
One by my bedside table to turn off all the lights and smart plugs.
One on my front door to set my away from home scene.
I also have a signed band poster hung on the wall with one, which opens the album in Spotify.
Good fun.
