NFC Tags and Wireless Charging (lemmy.world)

Maybe not the correct place but I know a lot of folks use NFC tags to trigger automation.

Does anyone have experience with a tag in-between their phone and the wireless charger? I have a few wireless charging stands I'd like to set automations to (ie: "I've set my phone on the nightstand charger, X,Y,Z lights should be set to red if they're turned on now"). I'm just not sure how close the freqs both use are (and even less sure of how much interference causes issues).

So yeah, has anyone used an NFC tag in-between their phone and wireless charger without melting either?

Do this.

Whether it would fry the NFC tag or not, you want as little distance as possible between the wireless charger and phone. More distance is less efficient (more heat, more wasted power, slower charging).
