Hass NFC - Control Home Assistant with NFC tags


#121

What a great app, my original plan was to integrate NFC in to Hassio using Tasker, but this is a way better solution. My NFC tags arrived today and I just bought the app, now I have a cheap garage door opener.

There was a question earlier in this thred about using a Samsung smartwatch to trigger the NFC tags. I have no idea, but maybe that can be achived using Tasker on the Android phone and TaskS2 app on Tizen? I use TaskS2 on my Galaxy Watch to trigger Tasker tasks that trigger events in Hassio.

cool, i was the guys asking for tizen, interesting! :slight_smile:
my tags arrive tomorrow
but i think the problem remains on tizen, that the NFC chip on the samsung can only be used for samsung PAY only, nothing else, but its worth a shot

Aaa…I see, I didn’t know that. But if you are interested in trigger Hassio using your smartwatch I recommend checking out Tasker and TaskS2, but it would be alot easier using NFC tho…

What exactly is stored on the NFC tag? Is there any security issues leaving one NFC tag outside to trigger my garage doors, is it possible to read whats on the tag and somehow use that information?


#124

On the tag the service you store is written. So for example light.kitchen with a value of “ON”. So if you use another app to read the tag you will find out what the tag should do. However, the Hass NFC app is needed to actually call the action to your HASS.

yes! very cool app. I puit a tag in front of every external door: open the phone, put it close to the tag, and zac the doors magically open.

I am just wondering if it is worth it to root the phone, so no need to unlock the phone first

Thanks for the kind words guys! Happy you’re enjoying my app! :slight_smile:

Hope for an IOS version! ( or help convincing wife switching from Ios to Android , but I think doing the app it’s easier :wink:)


#128

iOS doesn’t support this right now I believe (or has that been fixed?). I also don’t own iDevices and it’s proxy to create apps there unfortunately.


#129

Maybe a stupid question, but what is written on the NFC? The complete URL and ha token? So in other words, anyone that reads the tag, can activate the script?

Or is it linked with the Android device where the app is installed on? And no one else can use it


#130

The app on the device stores the token and URL. The token only saves the action that gets called. So for example light.kitchen with action toggle. You can download another app to read the tag to see the complete data if you want.

Ok good , so no one else can do anything with the tag


#132

That’s right.
