## Description

Refoss Smart Home Energy Monitor supports 2 main circuit sensors (up to 200A each) and 16 branch circuit sensors (up to 60A each) with easy-to-install clamp-on design. Keep track of your home's electricity usage anytime, anywhere with the Refoss app. And accurately monitors solar panel and wind turbine energy generation, providing real-time data on power output. This allows you to optimize the use of renewable energy, enhance energy efficiency, and reduce electricity bills with ease. Consumption alerts can be set for each circuit and you'll receive alerts for unusual energy spikes, and take proactive steps to lower your electricity bills and save more energy. It also easily accesses detailed electricity usage and cost graphs by minute, hour, day, month, or year, giving you deep insights into your energy consumption and empowering you to make smarter energy decisions.

Review: One of the best energy monitor systems - I have been trying out the Refoss EM16 Smart Energy Monitor for a while now, and I must say, I'm impressed. It was easy to install—good instructions and helpful online videos meant the whole process was simple and quick. Took about an hour to have everything up and running, and all plugged in to the Refoss app successfully. I like best that this product is so versatile and thoughtful in design. You can just plan and label your circuits ahead of time, and if a clamp is showing up in the negative direction, you can simply reverse it in the app without the need to rewire. If you require additional circuits to be monitored, you can bus their wires together into a CT so long as they're on the same phase. The application is simple to operate, giving real-time monitoring of all the circuits, and detailed energy history by day, week, month, or year. Home Assistant support is where this product really shines. EM16 auto-commands and provides complete local access to all the data of each circuit, enabling advanced automation without the cloud. Solar system owners will love Zero Feed-In Automation—putting extra solar energy to use powering devices such as EV charging points or water heaters rather than returning it to the grid. The recent firmware releases saw the addition of various useful features, including channel merging, export of CSV data, improved dashboards, and inverting CT readings in software. The releases show that Refoss is refining the product according to feedback from users. Overall, the EM16 is a wonderful, budget-friendly energy monitoring system—easy to install, full of data, and ideal for smart home residents as well as anyone wishing to gain better control of and track their home energy usage. Highly recommended.
Review: Best Smart Home Energy Monitoring Solution. - I am extremely happy that I bought this Refoss Smart Energy Monitor EM16 to track the energy consumption in my home. I did a favor myself by watching a couple videos on youtube to make sure that this product meets all my needs and I can handle the installation comfortably and I HIGHLY RECOMMEND YOU DO THE SAME. Product is packed pretty well with all items you need (except screwdriver and some protective gear) and also comes with a user manual. User manual includes Installation guide with step-by-step instructions, Troubleshooting Guide, Technical specifications and Warranty. First, I have read the manual and all step-by-step instructions and then unboxed the rest of the items. I opened up my panel and took a picture and on a white paper I wrote down what breakers are connected to line A or to line B, that helped me to decide on connecting Lc to La as more breakers that I am planning to monitor are connected to line A. In your case, it may vary so make sure to look at the picture of your panel and plan accordingly to meet your energy monitoring needs. Refoss Smart Energy Monitor supports up to 16 channels and comes with 16 connectors excluding A1 and B1 (they go on to your service lines). I followed the instructions from the installation guide, and I felt it was pretty straight forward. Few of my breakers (A/C, Dryer and Range etc.) are 2 poles so I used both channels A and B and merged those channels (You may use one and change Circuit factor). Their app has a good feature where you can merge channels and label them (I have labeled them as A/C, Dryer etc.). Their app has a handful of settings that you can customize your setup based on your installation. To name some settings here, you can name each channel, merge channels, circuit factors (helps in case of using one circuit on multipole breakers), consumption alert etc. I don't have the Home Assistant set up so I can't say what functionality you get there. I wish they support other Smart home platforms, so it helps many users with their integrations (Smartthings etc.). About customer/technical support aspects, I had an opportunity to work with their support team as I noticed an issue, after the contact they asked me to share photos, and they suggested some changes to make sure that it is not an issue with the product. After completing the suggested changes, the issue still persisted and that helped them determine it was an issue with the monitor, and they sent a replacement and after installing the new one it worked flawless. Though their support is by email, they are pretty responsive and very helpful and knowledgeable. About the Product design aspects, it is well designed by keeping DIY installations in mind. Concept of using headphone-jack style and clamp style connectors is pretty easy to handle and helps with quick installation. After 4 weeks of monitoring, I can say that Refoss Smart Energy Monitor EM16 is pretty reliable to monitor energy consumption, and I highly recommend this product.

## Questions & Answers

**Q: Does the Refoss EM16P work without Home Assistant?**
A: Yes, it works standalone with its own app for real-time circuit data, history, and solar monitoring. Home Assistant integration is optional but adds automations, custom dashboards, long-term logging, and circuit-level triggers.

**Q: Why is my electricity bill so high?**
A: Appliances like refrigerators, dryers, or EV chargers quietly use a lot of power. This smart power tracker monitors real-time usage per circuit, helping identify high-energy devices and reduce electricity costs by 10–20%.

**Q: I don’t want my energy data sent to the cloud. Is it safe?**
A: Yes. All data stays local. Access and manage it via Web UI or local API—no cloud, full control, and easy integration for smart home or automation setups.

**Q: Am I wasting solar energy?**
A: Excess solar power often goes unused. A solar power optimizer tracks solar production and automatically directs surplus energy to appliances such as heat pumps or dishwashers, boosting self-consumption and reducing electricity costs.

**Q: How can I spot energy-hungry or faulty appliances?**
A: The fastest way to get an ROI is eliminating Vampire Loads — devices that draw power even when “off.” Refoss alerts you to unusual or peak consumption so you can fix them before they drive up costs.

### ⭐⭐⭐⭐ Works well with Home Assistant on VLAN after a few settings changes; voltage monitoring is strange
*by E***N on 19 November 2025*

This is a Home Assistant specific review. If you are using the app and on a typical network, only #1 would be of interest. Overall it works great! It was easy to setup and integrate into home assistant. However there are a few things I did notice about it: 1. It has 3 sets of 6 channels and a voltage measurement for each. It does not work will if you have a single unit and want to measure an even number of circuits between 2 phases. (and by work I mean exact measurements. It will still be close) However I had 2 units so I was able to split the circuits and it worked out. For this I have to give it 4 stars as it does not easily support a typical split phase configuration. 2. It requires using their app and making an account for the initial setup and connection to wifi. The app will error out if your phone is on a different vlan than the wifi you selected but it still connects. 3. The unit requires internet access at least 1 time before working locally. 4. The home assistant integration that is officially supported automatically scans for devices and if it is on a different subnet, it will not be found. This can be solved by using the integration from HACS and entering an IP address. Overall I am happy with the device and that I do not need to flash custom firmware but still run it on an internet restricted VLAN with Home Assistant!
