There are two NFC tags with self-adhesive backs on Sonoff's plastic card, which can be set to run eWeLink automations (scenes) using an NFC-capable phone.

In order to use the NFC function, a Smart Control (Scene) must be created in the eWeLink app, in which the "Trigger" or condition that starts the run is not the status of another smart device or the data of a sensor, but touching an NFC tag.

After the automation has been created, the automation will run by touching the NFC phone, so with the help of NFC technology, we can start automations with a single touch without taking out the phone or running the eWeLink app.

The NFC scene can also be shared with family members with the SHARE HOME function, so they can also access the NFC touch automations.
