fingerguns.net · last updated

If you’ve got a Leviton Load Center and want to keep tabs on your home’s energy—especially if you have solar panels, a battery backup, or a generator—these Smart Mains Metering Accessories (LSMMA) are what you need. They’re basically clip-on current transformers (CTs) that you attach to the main service wires or breaker lines. The split-core design makes installation a breeze—no cutting wires, just open the clip, snap it around the conductor, and close it. You can connect up to three pairs of these to your Leviton Whole Home Energy Monitor (LWHEM-2R), and then see real-time and historical energy data right in the My Leviton app. It shows you how much power you’re using, how much your solar is producing, or what your generator’s putting out. Super helpful for spotting energy hogs, checking your solar output, or just geeking out on your home’s electricity flow. They’re designed specifically for Leviton’s system, so they work seamlessly. A smart upgrade for anyone serious about home energy management.
