Must-Have For Data-Driven Homeowners
This is a great tool for data geeks.I have an expensive residential electric bill. The data I have collected with this meter has helped me determine where my energy is going and allows me to monitor usage in real time.I live in Florida and have an older heat pump, so I was not surprised to learn that 45% of my usage is my heat pump compressor and 5% is my air handler. These measurements were taken during the summer. On the other hand, I was surprised to learn that my hot water heater is contributing to about 8% of my energy usage, which is more than I expected. If/when I replace the water heater, I now have data to justify spending extra on a more efficient water heater.I’m impressed at how accurate the data is. I compared the total usage per day with my electric company’s web portal (Duke) over a two-week period. The meter was consistently 1% to 1.5% less than what Duke was showing. So, while the accuracy was off about 1%, the consistency was less than .5%.Installation was fairly simple. I made the mistake of closing up my breaker box before confirming the meter was properly connecting to the app via wifi. I had to go back into the breaker box and fix one of my connections providing power to the meter. Otherwise, it went smooth.I purchased some insulated electrician’s gloves and made sure I was standing on a rubber mat since I don’t have an external main breaker between my breaker box and my Duke electric meter. This meant that even though my breaker box main was turned off, the lines coming in were still hot.I wish there was a version of this meter with 24 or 32 ports. I had to choose the circuits to monitor, and so I have quite a few circuits that are not individually monitored. In the app, the circuits that are not monitored show up at the bottom as “Balance”. In my case, the “Balance” is usually about 15% of my total usage.The app is easy to work with. I like that it will summarize data by hour, day, week, and month. Being able to see usage by week or month provides better averages for specific circuits. For example, if we run the clothes dryer several times on one day, but not at all on another day, the monthly average usage is going to provide realistic data.Overall, I am very satisfied with this purchase.

Perfect for a private home assistant setup
Very satisfied with this product! Excellent value for the price. I’ve been using it for a few months now together with Home Assistant, and it has worked flawlessly.As a European user, I found the documentation a bit US-oriented at first, so I had quite a few questions during setup. Their support team was outstanding — quick, detailed, and patient in answering all my concerns. Thanks to them, I now have a clear understanding of how everything works. They even sent me an extra part I needed for my European setup at no cost, which I really appreciated.My board has 28 circuits, but since circuits on the same phase can be combined, I was able to cover everything with the 16 clamps included. The measurements are very accurate — I compared them against some smart plugs with built-in power meters, and after several weeks of monitoring, the readings matched closely.Updating the firmware through the app was also a big plus. It allowed me to change the reporting interval from 30 seconds to just 2 seconds, giving me near real-time insight into my energy usage. I started out using their cloud integration with Home Assistant, but later switched to the private local setup. Everything now connects directly to Home Assistant without needing the internet — and the setup was much easier than I expected.

High quality with accuracy
Very Very high Quality parts and well thought out. easy to install, very detailed instruction manual with large pictures and large fonts. After 7 days of monitoring it was very close to the daily usage on Duke energy website. I have found some ways to save electric with this system. How great it is in real time, can switch to amps, watts, or Kwatts. even gives costs $$$ when you put in the KW cost. I can not say enough good for this product. And by the way Tech support is fast and concerning. A must have system

Great Smart Energy Monitor with Minor Accuracy Quirks
This smart home energy monitor has been a fantastic addition to my setup. Installation was straightforward, the app is intuitive, and I love being able to see real-time energy usage for the whole house. It’s really helped me become more mindful about what’s using the most power and when.That said, I did notice a small discrepancy when comparing it to my utility power meter—the readings are consistently off by a few percentage points. Not a huge deal for general monitoring, but if you’re looking for ultra-precise data, it’s something to keep in mind. This meter is usually 20-50kwh under what the power company meter says im using. Again this is not a huge deal at all to someOverall, it’s a solid product with powerful insights and great functionality. Just shy of perfect due to the slight inaccuracy, but still absolutely worth it for most homeowners.
