What the maker puts in writing

  • 120 V / 15 A / 1,800 W · ETL and FCC
  • Matter, over Bluetooth and 2.4 GHz Wi-Fi
  • Alexa, Apple Home, Google Home, SmartThings; GHome, Smart Life, Tuya apps
  • Cycle, random and countdown timers; scenes by temperature, humidity or weather
  • Hub needed only for direct ecosystem connection

The qualification most Matter listings omit

Matter‑compatible Hub only required for direct connection to Alexa, Apple Home, or Google Home apps. Otherwise, use GHome first, then link to Alexa/Google.

Matter is sold as the end of vendor apps. In practice, without a hub, you are back in the vendor app — and this listing says so twice.

That is worth more than the badge.

One model number, two products

GHome’s non-Matter plug on this shelf also reads WP3. It costs ten dollars, has no published amperage, and talks only to Alexa and Google.

Check the barcode, not the model.

The questions that keep coming up

Do I need a Matter hub?

Only for a direct connection to Alexa, Apple Home or Google Home. The listing says so and offers the alternative: set the plug up in the GHome app and link from there. That is unusually candid — Matter is often sold as hub-free without the qualification.

Why does it share a model number with a cheap plug?

Both GHome plugs on this shelf carry the reference WP3, at 9.99 and 31.99 dollars, with different barcodes. One is Matter and publishes 15 A; the other is not and publishes no rating. When ordering, the model number alone will not tell you which you are getting.

What are cycle and random timers for?

Cycle repeats on and off at an interval — useful for a fan or a pump. Random varies the time, which is what makes holiday lighting look occupied. Only this plug on the shelf publishes either.
