Review: Great Whole-Home Energy Monitor with Home Assistant Support! - I’ve been using the Refoss Smart Energy Monitor for a week now, and I’m thoroughly impressed. One of the standout features is its local integration with Home Assistant, which is precisely why I chose this energy monitor. The instructions were straightforward, and the video on the desertcart listing was particularly helpful, guiding me through the entire installation process. It should be relatively easy for anyone with basic electrical knowledge and some handy skills. However, I recommend doing some pre-planning before installation to determine which circuits you want to monitor. There are five L1 circuit sensor, five L2 circuits sensor, and six circuits sensor that can be used on either L1 or L2. You’ll need to choose one or the other. Additionally, you can combine some circuits and use one clamp for them, as long as they don’t exceed the current limit of the circuit sensor. For instance, I combined two kitchen outlets into one, saving me a sensor I used for monitoring a different. For balanced 240V loads like an AC unit or an EV charger, you can use one clamp and then change the circuit factor to 2 in the Refoss app or create a helper in Home Assistant that multiplies the energy usage by 2. This is because with balanced loads, the energy drawn on both lines is the same, which is why it’s called a balanced load. This way, you can save a sensor to monitor another circuit. I highly recommend making a note of which sensors are connected to which circuits to avoid wasting time trying to remember where you connected them. Setting up the energy monitor on the app was a breeze. I simply downloaded the Refoss app, followed its instructions to connect it to Wi-Fi, and updated the software of the energy monitoring module. The Refoss app allows you to monitor live energy usage for each connected circuit and view a history of energy usage for each circuit, broken down by day, week, month, and year which is awesome for using the app on its own. Connecting to Home Assistant was equally easy. I searched for the Refoss add-on, and the energy monitor was automatically detected on my network. It brought over all the entities shown in the Refoss app and then I got to setting up everything in home assistant. Overall, I highly recommend this affordable and reliable whole-house energy monitoring system. If you use Home Assistant, this is one of the best options out there that is supported natively through the Refoss addon.
Review: Smart Home Energy Monitor – Worth It! - This energy monitor is awesome if you're into smart home setups. It works with Home Assistant, tracks your electricity use in real time, and helps cut down your bill with smart alerts for weird spikes—like appliances running when they shouldn’t. The latest update added some cool features: you can merge circuits, export hourly data as CSV, flip sensor readings without rewiring, and check out a cleaner dashboard. It’s great for solar setups too—automatically powers your EV charger or water heater when solar is peaking, so you don’t feed energy back to the grid. You get up to 36 months of data stored in the cloud, and the app makes it easy to spot what’s wasting power. Setup is simple, it supports a bunch of system types, and the sensors are solid (just handle them carefully). Overall, super useful and easy to manage!

## Features

- ✨NEW✨ Feature Release (25.07.30): 1.Merge channels; 2.Export hourly-level energy data; 3.Access the new energy statistics page; 4.Invert CT readings directly via Device Settings → Circuit Factor (no physical flipping needed!). Update to the latest Refoss app and firmware to enable all features.
- Refoss Smart Home Energy Monitor is ETL Certified and supports 2 main circuit sensors (up to 200A each) and 16 branch circuit sensors (up to 60A each) with an easy-to-install clamp-on design. Compatible with single-phase 2-wire systems, single-split phase 3-wire systems, and 3-phase 4-wire Wye systems with earthed (TN or TT) neutral (no Delta). Easily installs in most home circuit panels and includes a 2-year warranty. Attention: Take care when handling the included current transformers to avoid damage.
- 24/7 Energy Monitoring: With the Refoss app, you can track your home’s energy usage anytime, anywhere. Easily monitor the power, current, voltage, and power factor of major appliances like air conditioners, stoves, and water heaters. Quickly identify which devices are running efficiently and which ones might be wasting electricity. According to statistics, many users save an average of 10%-20% on their energy bills by optimizing appliance usage.
- Zero Feed In Automation: The EM16 is a smart meter designed for solar owners, linking with Home Assistant to automate your zero feed-in strategy. Ideal for homes with solar panels, it detects solar surplus (like midday sun peaks) and automatically powers high-energy appliances - such as activating your washing machine, EV charger, or water heater - to consume excess solar energy onsite. This prevents low-value electricity feed-ins to the grid, maximizing your solar investment returns and slashing utility bills.
- Comprehensive Energy Data: The power monitor provides 98% accuracy and stores up to 3 years of detailed electricity usage data. With clear minute, hour, day, month, and year consumption and cost charts, you can easily understand your energy use. Ideal for homeowners adjusting appliance usage to save on bills or businesses tracking long-term energy savings and emission reductions. Historical data can also be exported for further analysis, making every electricity expense transparent.
- Smart Consumption Alerts: You can set personalized usage targets for each circuit. Once the system detects an unusual energy spike—such as a sudden increase in power consumption by an appliance that exceeds the normal range—you will immediately receive a detailed alert notification. This allows you to take prompt action, such as checking if there is a malfunction with the device or adjusting your usage habits, thereby optimizing appliance usage across different times of the day.
- Compatible with Home Assistant: EM16 Wi-Fi Energy Monitor is now compatible with Home Assistant! Simply update the firmware in the Refoss app to seamlessly integrate your energy management system with your smart home platform, enabling centralized control and automation. Additionally, all data is stored locally, ensuring your privacy is protected without cloud processing. API is not supported.

### ⭐⭐⭐⭐ Solid Hardware, Great for Home Assistant, App Just Needs Some Love
*by R***N on October 14, 2025*

So far, the Refoss 16-channel power meter has been pretty solid. Install was straightforward, and the hardware feels high quality — about on par with Sense or other higher-end monitors I’ve used. My only small gripe on the hardware side is that it’d be nice if Refoss offered some CT clamp extension cables to help clean up wiring in a 200-amp panel. I have had no issue with the units integrated wireless receiver and it has been very reliable. The app itself is decent, but if you’re coming from Sense, it’s definitely a step down in polish. There’s no device detection or load learning, which feels like a weird omission these days. I’d love to see options to merge CTs in the app or have a bit of smart recognition when certain appliances (like the fridge or microwave) kick on. That said, this thing absolutely kills it with Home Assistant. That’s really where it shines. Setting up automations and triggers off individual clamp readings has been way more reliable than Sense ever was, and honestly, that alone makes it worth the upgrade. Overall, the Refoss delivers great hardware, accurate readings, and solid integration potential. The app could use some love, but if you’re the kind of person who enjoys tinkering and wants full control over your power data, this is a great pick.
