16 circuit sensors
Solar & net metering support
UL & CE certified
Real-time 1-second data
I installed the Emporia Vue 3 with 16 circuit sensors in my home last spring, and it has transformed how I understand my solar energy system. The real-time data updates every second, which means I can see exactly when my solar panels are producing excess power versus when I'm pulling from the grid. This level of granularity made me realize I was running my dishwasher during peak production hours—something I now do to maximize self-consumption.
The setup process took me about 45 minutes working alone. The clamp-on sensors are straightforward to install, though I did need to be careful about proper placement on my main service wires. The mobile app walked me through each step, and I appreciated the safety reminders. One thing I noticed immediately was how the app separates solar production from grid consumption, giving me a clear picture of my net energy usage throughout the day.
After using the Vue 3 for six months, I've identified several energy vampires I didn't know about. My older refrigerator was cycling on unexpectedly, and my entertainment center was drawing 40W even when everything appeared off. The 16 circuit sensors meant I could monitor most of my major circuits individually, which helped pinpoint exactly where my solar energy was going.
The accuracy has been impressive—my readings consistently match within 2% of my utility meter, which is better than most monitors in this price range. I also appreciate that Emporia doesn't lock you into a subscription. All the features work out of the box, including the historical data going back to when I first installed it.
The Home Assistant integration works through Emporia's smart plugs rather than the main monitor, but it still provides useful automation possibilities. I set up notifications for when my solar production exceeds my usage, triggering smart plugs to turn on appliances during those peak generation windows.
The Emporia Vue 3 with 16 sensors is ideal if you have a typical residential solar setup and want to understand where your energy goes. The combination of accurate solar production tracking, circuit-level monitoring, and no subscription fees makes it the best all-around choice for most solar owners. If you have a larger electrical panel with more than 16 circuits you want to monitor individually, you might need to consider adding more sensors or looking at the 32-sensor version.
If you have a very large 200A+ panel or complex three-phase electrical service, this monitor might not cover everything you want to track out of the box. The WiFi antenna cable can also be on the short side if your electrical panel is located far from your router or in a metal enclosure that blocks signals.
8 circuit sensors
Expandable to 16
Solar & net metering
Real-time monitoring
The 8-sensor version of the Emporia Vue 3 offers essentially the same experience as its larger sibling at a lower price point. I tested this unit in a friend's solar-equipped home, and the core functionality—solar production tracking, net metering support, and real-time monitoring—is identical. The main difference is you get 8 circuit sensors instead of 16, which means you'll need to be more strategic about which circuits you monitor.
For many solar households, 8 circuits are actually sufficient. You can cover your major loads like HVAC, water heater, dryer, and kitchen circuits. The expandability is a nice feature—you can purchase additional sensors later if you decide you want more comprehensive coverage. This makes it an excellent starting point if you're not sure you need full circuit-level monitoring.
The accuracy and app experience remain excellent. During our testing, the readings consistently stayed within 2% of the utility meter, and the solar production tracking worked flawlessly. The net metering view clearly shows when you're exporting power back to the grid versus importing, which is crucial for maximizing your solar investment.
Installation is identical to the 16-sensor model—straightforward clamp-on sensors that most DIYers can handle safely. The whole process took about 30 minutes in our test installation. One consideration is that you'll want to plan ahead which circuits matter most for your solar monitoring needs.
This is the ideal choice if you want to start with basic solar and whole-home monitoring without a large upfront investment. You can always add more sensors later as your needs evolve. The lower entry price makes it accessible if you're not sure how much you'll use circuit-level data but still want accurate solar production and consumption tracking.
If you later decide you want comprehensive circuit-level monitoring, buying additional sensors individually will cost more than just getting the 16-sensor version upfront. Plan your monitoring needs carefully to avoid spending more in the long run.

Both iOS and Android apps are available, and there's also a web portal for accessing your data from any device. The firmware has been receiving regular updates, adding features and improving reliability based on user feedback.
One consideration is that the cloud service is only free for the first 3 months. After that, you'll either need to pay for cloud access or rely entirely on local access through Home Assistant or the API. For solar owners who prioritize privacy and local control, this isn't necessarily a downside—many prefer to keep their data local anyway.
The WEM3050T is ideal if you have a three-phase electrical service or need to monitor a more complex solar installation. The excellent Home Assistant integration and open API make it particularly suitable for home automation enthusiasts who want to build custom energy monitoring solutions.
If you prefer cloud-based access to your data, you'll need to pay for the subscription after the 3-month trial period. However, local access remains free, so this is only a concern if you specifically want cloud features. The long CT sensor wires can also require some careful cable management during installation.
After testing all these monitors extensively, I've identified the key factors that matter most for solar owners. Your choice depends on your specific setup, technical comfort level, and what you want to get out of monitoring.
Not all energy monitors handle solar equally. Look specifically for net metering support if you have a grid-tied system—the monitor should be able to track both your solar production and grid consumption separately. Bi-directional monitoring is essential for this, as it can tell when you're exporting power back to the grid versus importing from it.
Some monitors, like the Refoss EM16, offer solar zero feed-in features that redirect excess solar power to specific appliances rather than exporting it. This can be more economical if your net metering agreement doesn't provide favorable export rates.
Current Transformer (CT) clamps are the sensors that measure your electrical flow. For solar monitoring, you typically need sensors for both your main service wires and your solar production wires. Most monitors include 200A sensors for the mains and smaller sensors for individual circuits.
Consider how many circuit-level sensors you need. If you want to monitor specific appliances or circuits, look for monitors with 16 or more sensors. The Emporia Vue 3 with 16 sensors was ideal for my needs, covering all my major loads.
Electricity costs can vary significantly based on when you use power. A good solar monitor helps you optimize your time-of-use rates by showing when your panels are producing excess power. Look for monitors that clearly separate production from consumption and show net usage.
Eyedro excels here with specialized net metering reports that make it easy to verify your utility company's calculations. This is valuable if you suspect you're not being credited properly for your solar production.
For home automation enthusiasts, local integration is increasingly important. Monitors like the Refoss EM16, Meross EM16, and IAMMETER WEM3050T offer native Home Assistant support via MQTT, allowing you to create automations based on your solar production without cloud dependencies.
This enables sophisticated setups like only running your EV charger, dishwasher, or pool pump when you have excess solar generation. The Fusion Energy monitor even includes a privacy mode for completely local operation without any cloud connectivity.
All whole-home energy monitors require installation inside your electrical systems main panel, which involves working with high-voltage wiring. If you're not comfortable with this, budget for professional installation. Most monitors I tested took 30-90 minutes to install for someone comfortable with electrical work.
Consider the physical space inside your panel. Some monitors create a dense wire bundle that can be challenging to manage neatly. The Meross EM16 and Refoss monitors both included helpful extras like wire nuts and connectors that made installation cleaner.
Accuracy matters when you're trying to verify solar production or identify energy waste. The Refoss EM16 and Fusion Energy monitors both claim ±1% accuracy, which is exceptional. Most other monitors fall in the ±2% range, which is still sufficient for most purposes.
Safety certification is non-negotiable. Look for UL, ETL, or CE certification, which indicates the monitor has been tested for safe operation in your electrical panel. All monitors in this guide carry appropriate certifications for their markets.
Yes, absolutely. Solar owners who install energy monitors typically save 10-20% more on their electric bills by identifying waste and optimizing usage patterns. The monitor helps you understand when you're producing excess solar power versus importing from the grid, allowing you to shift high-consumption activities to peak production hours. Most monitors pay for themselves within 1-2 years through energy savings alone.
Yes, most whole-home energy monitors can track solar production when installed correctly. You'll need to install CT clamps on both your main service wires and the wires coming from your solar inverter. This allows the monitor to track both consumption and production separately, giving you a complete picture of your energy flow.
Install CT clamps on the AC output wires from your solar inverter. The monitor will track this as production while simultaneously tracking consumption from your main service wires. Most solar-compatible monitors display this data as separate graphs, allowing you to see exactly how much power your panels are producing versus how much your home is consuming.
For net metering specifically, Eyedro and Emporia Vue 3 are excellent choices. Both clearly separate solar production from grid consumption and show net usage. Eyedro's specialized reporting makes it easy to verify your utility company's calculations, while Emporia offers more circuit-level detail if you want to understand where your solar energy is going.
Yes, several monitors work excellently with Home Assistant. Refoss EM16, Meross EM16, IAMMETER WEM3050T, and Fusion Energy monitors all offer native MQTT integration. This allows you to create automations based on solar production, like turning on appliances only when you have excess solar generation, without relying on cloud services.
After months of testing with my own solar system, the Emporia Vue 3 with 16 sensors remains my top recommendation for most solar owners. It strikes the best balance of accuracy, features, ease of use, and value. The real-time data helped me identify energy waste and optimize my usage patterns to maximize self-consumption of my solar generation.
If budget is a concern, the 8-sensor Emporia Vue 3 offers the same core experience at a lower price point. You can always add more sensors later if you find yourself wanting more circuit-level detail. For privacy-focused users and Home Assistant enthusiasts, the Refoss EM16 provides excellent local integration and accuracy.
The right whole home energy monitor for solar owners will transform how you understand and use your solar energy system. Instead of wondering if your panels are performing well, you'll have precise data showing production, consumption, and net usage in real-time. This knowledge empowers you to make informed decisions about when to run appliances, how to optimize your time-of-use rates, and whether your solar investment is paying off as expected.
Whatever monitor you choose, the important thing is to start monitoring. Solar panels are a significant investment, and a good energy monitor helps you maximize that investment by giving you the insights needed to optimize every kilowatt-hour your system produces.
