From this table, it’s clear that both monitoring system offers a bunch of features and they both have some features that make them better than each other. Seems complicated to decide? That’s why we’re gonna compare them in detail to make things convenient for you.  


  • The IoTaWatt is a single-unit device that can monitor up to 12 circuits, while Emporia is a multi-unit device that can monitor up to 16 circuits.
  • It uses 50mA CTs for accurate power measurement, while Emporia uses 333mV CTs, which is less accurate than the IoTaWatt.
  • When it comes to IoTaWatt, the data is stored locally on the IoTaWatt device, so you don’t require an internet connection to access it. 

On the other hand, in terms of Emporia, the data can be stored locally on the Emporia device or in the cloud.

  • The IoTaWatt can be integrated with popular smart home platforms. For example, Home Assistant and HomeKit. Meanwhile, the Emporia can also be integrated with such platforms like Home Assistant and SmartThings.
  • Both of them are highly compatible with solar systems, making the systems overall energy efficient.

Therefore, it can be said that both are uniquely good in their field and you can’t say one of them better than the other straightforwardly.

Which One Should You Choose Between IoTaWatt and Emporia?

As both of them don’t have a significant number of better features than the other one, the best energy monitoring system for you will mostly depend on your individual needs and budget. If you’re a technical expert, looking for customization, higher accuracy, and don’t hesitate about local data storage and higher price; then the IoTaWatt is the better option. 

On the other hand, if you’re a regular user, prefer a simple and user-friendly system, and looking for a more affordable option; then you should go for the Emporia.

Frequently Asked Questions and Answers (FAQs)

How does Emporia Vue Gen 2 work?

The Emporia Vue Gen 2 home energy monitor uses two sensors that are attached to the main one. But it comes with 16 additional sensors that should be attached to individual circuits inside the electrical panel. It supervises total energy consumption and then determines consumption per circuit.

What is the best home energy monitor?

You can find numerous energy monitoring systems available but only a specific number of them provide better performance and results. Those are – Wiz Connected smart plug with energy monitoring, Eve Energy smart plug with energy monitoring, Humax wifi smart plug with energy monitoring, TP-Link Tapo P110 energy monitoring smart plug, etc.

Are home energy monitors worth it?

Truth to tell, simply buying and installing an energy monitor isn’t gonna save your energy or money. The fact is they can help you by highlighting the way you can use energy efficiently in your house and suggest where you can save.


Lastly, it can be said that there isn’t an actual winner between them. Both are comparatively the same as the other one. The only thing that matters in this case is your requirement and affordability. So, focus on what kind of features you gonna utilize more and choose a home energy monitor according to it.
