Review: 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. Review: Great Product at An Awesome Price! - I've been using this for a while now. It's a great replacement for my old monitor with a lot of new features. Installation is easy and straight forward, the split current transfers make that very easy. The app works well and it's already set up for Home Assistant integration and the ability to use that as your server so no need to sed data out of your home. I had one small problem that tech support quickly and professionally took care of. I have 4 panels and lots of circuits to monitor so I will be buying several. ## Features - ⚡ EASY INSTALLATION: Installs in circuit panel of most homes with clamp-on sensors.

It's a great replacement for my old monitor with a lot of new features. Installation is easy and straight forward, the split current transfers make that very easy. The app works well and it's already set up for Home Assistant integration and the ability to use that as your server so no need to sed data out of your home. I had one small problem that tech support quickly and professionally took care of. I have 4 panels and lots of circuits to monitor so I will be buying several. ### ⭐⭐⭐⭐⭐ Easy to install, external SMA antenna, calculates real-time phase balance. *by S***N on October 19, 2024* Kit comes with SMA antenna extension cable that you can run outside of the panel to connect the included external antenna. Module has Bluetooth provisioning and connected to WiFi with no issues. Data is stored in 1 hour, 1 day, 1 week, 1 month and 1 year buckets. Real phase load balance is computed instantaneously. Circuit editor allows you to name each sensor and provide voltage multiplier to correctly account 2 phase loads. Another pane graphs the data. The same time range buckets are used for graphical representation. You can also export the data in tabular format for further processing if necessary. App also allows you to set alerts and also change cost per kilowatt to benchmark utility meter. My particular interest is in benchmarking HVAC efficiency and tracking large unknown loads in my house. The device will help me to answer questions such as when is the best time to top off refrigerant in my 2 HVAC units, is it time to replace my refrigerator, is the battery in my EV getting too old, do smart switches consume more energy to run than power they help to save with schedules and timers, is the basement sump pump just tripped the circuit breaker, is the septic tank air pump still working or blew mechanical fuse, etc. My main panel has 40 breakers, this device has only 16 channels. But I figured that if I run 3 wires per sensor for 8 sensors, plus 2 wires per sensor for another 8 sensors, I will cover the entire panel. The important thing is to ensure that all the wires going through the single sensor are connected to the same phase. Odd breaker rows are connected to phase 1, even rows to phase 2. I have 5 double breakers installed in this panel. I connected them to 5 sensors and used x2 multiplier in the app to correctly attribute 240V loads. Wires are cut without any slack in my panel, and bundling 3 wires together through the same sensor was difficult. I used plastic zip ties to reinforce hinges and latches on low gauge wires. Main module can be connected to 3 phases max. I used only the first 2 and connected the 3rd wire to the neutral as instructed in paper and app guides. Kit includes 3x 12th gauge wires and 3x wire connectors to connect multi strand power wiring to breakers in case if you don't have 2 spare empty slots to install dedicated breakers to power this module. ## Frequently Bought Together - Smart Home Energy Monitor with 16 50A Circuit Level Sensors, Measure Power Usage in Real-Time, History with App (16 50A Circuit Level Sensors) - Compatible with Home Assistant - 2 Pieces AC Current Voltage Amperage Power Energy Panel Meter LCD Digital Display Ammeter Voltmeter Multimeter with Split Core Current Transformer CT AC 80-260V 100A Multi-Function Power Monitor - Upgraded Watt Power Meter Plug Home Electrical Usage Monitor Consumption, Energy Voltage Amps Kill Tester with Backlight, Overload Protection, 7 Modes Display --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/651734759-smart-home-energy-monitor-with-16-50a-circuit-level-sensors](https://www.desertcart.vn/products/651734759-smart-home-energy-monitor-with-16-50a-circuit-level-sensors) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-22*
