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?

Where is the NFC sensor in the phone compared to the charger ring ? with any luck you can physically position the tag off the charging stand but still have it pickup. If not put it next to the charger, tap and use tasker or whatever to detect charging within a certain time, combined with the tag detection and send to HA. Tap again after charging to turn off.

Yes, NFC is probably at the top of the phone, charging coil is below the camera island.
