How to drive Philips Hue lighting with NFC tags Recently I came to use my NFC tags again.
Wondering how I can use my NFC tags to automatize chores like:

Turn the light on at noon (Alexa/Philips Hue)
Turn the light off at midnight

In essence I intent to use NFC tags as replacement for conventional light switches!
I could not find any way to do this using the standard apps (NFC Tools / Trigger). I am not bound to a specific app solution.
I tried to use text-to-speech to verbalize Alexa commands with NFC Tools, but this failed since it seems a synthetic voice is not recognized.
I think you're misunderstanding what an NFC tag is.  The tag has an ID number.  All it signals to the phone is &quot;You just identified this tag as me&quot;.  Some app has to be looking for that tag ID, and have code to do something when the phone sees it.
You can use one tag to turn the light on, and another to turn the light off - but you don't use a tag to &quot;turn the light on at noon&quot;, you just develop an app (or find one in Play) to turn the particular device on at noon (and the same thing for turning it off at midnight).
Google Assistant might even work - tell it to turn the light on every day at noon and turn it off every day at midnight.
