15 A Smart Plug for Voice-Controlled Homes

This Wi-Fi smart plug connects to a 2.4 GHz network without a hub and is certified to 15 A. Setup uses the eWeLink app and takes minutes. It works with Alexa and Google Assistant for voice commands. The unit suits anyone wanting simple, app-based control of a single outlet.

2.4 GHz Wi-Fi Only — No Hub, No Zigbee

The plug communicates solely over 2.4 GHz Wi-Fi and does not support Zigbee or other protocols. A compatible router on that band is required for pairing and ongoing control. If your network is 5 GHz only or you prefer a hub-based Zigbee mesh, this model will not connect.

15 A Capacity Handles Most Household Loads

At 15 A the plug can switch typical appliances such as fans, lamps and small kitchen devices. It is not rated for continuous loads above that figure, so high-draw equipment like space heaters or large air-conditioners must use a different circuit. The timer function supports up to eight scheduled or countdown events per day.

Questions about this item

Which version of the S31 Lite should I pick for a 15 A load?

The S31 Lite is rated for a maximum of 15 A, so a single unit covers that requirement.

What does the 15 A rating mean when the plug is installed in a real circuit?

It means the internal relay can switch resistive loads drawing up to 15 amperes continuously without overheating.

The plug uses a 2.4 GHz wireless link — what does that standard limit in practice?

The 2.4 GHz Wi‑Fi connection ties the device to a 2.4 GHz router band and the eWeLink cloud for remote and voice control.
