Smart Plug With Energy Monitoring

The Black & Decker EMSO1-1 is a WiFi smart outlet that switches 120 V loads up to 10 A continuous or 15 A peak for one hour per day. It measures real-time power consumption in the Emporia app so users can identify wasteful standby draw on lamps, fans or small appliances. The plug fits a standard North American receptacle and operates indoors from 14 °F to 140 °F.

Check Your Circuit And Wi-Fi First

Verify the outlet supplies 120 V and that the device you plan to control draws no more than 10 A continuously or 15 A for a single hour each day. The plug connects only to 2.4 GHz Wi-Fi networks; 5.0 GHz bands are not supported. Ensure your router broadcasts a 2.4 GHz SSID and that the installation location stays within the stated temperature range.

App Scheduling And Remote Access

The Emporia mobile application provides on/off scheduling, real-time status checks and manual toggle control from anywhere with an internet connection. Energy data is logged per outlet, letting you track wattage and estimated cost over time. No additional hub is required; the plug joins your existing 2.4 GHz network directly.

Questions about this item

What comes in the box and do I need to buy a hub or bridge separately?

The pack contains one smart plug. No hub or bridge is required; the plug connects directly to a 2.4 GHz Wi-Fi network and is controlled through the Emporia app.

Should I choose the 10 A continuous or 15 A peak rating for my device?

Use the 10 A continuous limit for appliances that run steadily. The 15 A peak is only allowed for up to one hour per day, so check the device label before plugging it in.

What does the 1200 W figure mean once the plug is installed?

It represents the maximum power the outlet can deliver at 120 V. Staying below 1200 W keeps the plug within its 10 A continuous rating and prevents overload.
