Smart Home Energy Monitor Supports Home Assistant, Real-Time Accurate Energy Consumption Tracking, Electricity Usage Monitor with 16x60A Circuit Sensors, 36-Month History, Solar Metering, 2.4G

I’ve been using the Refoss Smart Home Energy Monitor (EM16) for a few weeks now, and I’m seriously impressed with what it offers. As someone with a solar setup at home, I was particularly drawn to the Zero Feed-In Automation feature—and it works beautifully. Now, instead of sending excess power back to the grid for pennies, the system smartly kicks on high-energy appliances like my water heater and EV charger when solar output peaks. It’s already making a noticeable dent in my utility bills. Installation was straightforward with its clamp-on design, though I'd recommend a bit of caution when handling the current transformers as instructed. Once installed, everything syncs quickly with the Refoss app, which is clean and user-friendly. You get real-time data for each connected circuit—power, voltage, current, and power factor—plus clear breakdowns by minute, hour, day, and even year.The recent update (July 2025) added some killer features:✔ Merge channels✔ Export hourly-level data✔ New energy stats page✔ Invert CT readings without physically flipping the wires (huge time-saver)Another highlight is the smart alerts. I set thresholds for various appliances, and when something goes over the limit—like my dryer running longer than expected—I get an instant push notification. Great for both safety and savings.Also, it integrates with Home Assistant, which lets me automate energy usage smarter than ever. I love that all data stays local—no cloud dependency, which is a big privacy win. Only downside? It doesn't support Delta 3-phase, but for typical residential setups, this thing is perfect. Bottom line: Whether you're just energy-conscious or running a full solar + smart home setup, the Refoss EM16 is absolutely worth it. I’ve already seen more control over my energy usage and expect long-term savings. Highly recommend!

I’ve been using this smart home energy monitor for a few weeks, and it’s been a fantastic addition to my setup. Installation was straightforward, and it works seamlessly with Home Assistant. The real-time tracking is super accurate, and the ability to monitor up to 16 individual circuits has helped me pinpoint exactly where my energy is going. It even supports solar, so I can track both usage and production in one place.The Wi-Fi connection has been stable, and I really appreciate the 36-month data history for spotting trends. I can even check it if I am away and not at home. If you're into home automation or just want better insight into your power usage, this is a great investment. It’s already helped me make smarter energy adjustments to my home.

Have this product managing power usage in out house along with the Homeassistant management software. It took about 2 hours to plan out and install. While I was comfortable doing the work myself as an electrical engineer. I wouldn't recommend it for most DIY folks unless they are able to completely disconnect their main outside the house before the breaker box.Wifi connection worked great. VLAN automatically setup with no issues. Size was good for my breaker box, not sure if it would be as easy for an older or smaller box.Two issues I had, the install is a total mess of wires... it wasn't that easy to clean up. Wish there was a way to integrate current monitors into the breakers themselves. Second issue is the current readings were ALL backwards, despite following the directions to a T. Fortunately you can toggle this by adjusting your multiple from positive to negative in the app. Unfortunately thats annoying to do because of some android bugs making it hard to type "-" in their app?Look is ok if you don't mind the rats nest of orange wires in your breakerbox.Cost seems appropriate given the components included. Just wish they included another 5-10 breakouts to cover a full box, or at least the capacity to add them from an expansion kit.Kit should be durable and last for years with no major moving parts. Curious to see how well the plastic clips hold out over the years if I have to move it ever...

Super easy to set up and works perfectly with Home Assistant. I can see real-time usage for each circuit and even track my solar. It’s helped me understand where my energy is going — highly recommend!
