SONOFF S31 is a compact and lightweight US standard Wi-Fi smart plug with power monitoring. Both S31 and S31 Lite are UL certificated, this means they reach the indispensable security and reliability standard that a smart plug must have. Note that power consumption and over-load protection are available for S31.
The smart plug lets you control home appliances via eWeLink APP anywhere, anytime. Also, third-party platforms like Amazon Alexa and Google Assistant can seamlessly work with this plug for a voice-controlled home. The small size makes the smart plug will not occupy another outlet of your socket or power strip during, which reserves more space for other plugs. Convenient to use, plug and play.
