Whether you're looking to identify energy-hungry devices, set up automated power-saving schedules, or simply gain better control over your electricity costs, I'll help you find the perfect energy monitoring smart plug for your specific needs and budget.

TP-Link Kasa Smart Plug HS110 – Best Overall

After extensive testing across multiple smart plugs, the Kasa HS110 consistently delivers the most comprehensive energy monitoring experience. What sets this plug apart is its real-time energy tracking that goes beyond basic usage notifications—you get detailed wattage readings, daily/monthly consumption reports, and accurate cost calculations based on your local electricity rates.

The integration capabilities are impressive, working flawlessly with Alexa, Google Assistant, and Samsung SmartThings. I particularly appreciate the Away mode feature, which creates random on/off patterns to simulate occupancy for security purposes. The Kasa app provides intuitive energy analytics that helped me identify several phantom power draws in my home office setup.

However, the bulky design is genuinely problematic—it completely blocks adjacent outlets on standard wall plates. Despite this significant drawback, the HS110 remains my top recommendation for users seeking reliable, detailed energy monitoring combined with robust smart home integration. The data accuracy and comprehensive features justify the inconvenience for most energy-conscious users.

Amazon Smart Plug – Budget Pick

For Echo users seeking basic energy awareness without breaking the bank, Amazon's own smart plug delivers surprising value. While it lacks the detailed analytics of premium models, it provides essential energy monitoring through simple notifications in the Alexa app when devices exceed typical usage patterns.

The setup process is remarkably streamlined—just plug it in and say “Alexa, discover devices.” The compact design is a genuine advantage, allowing normal use of adjacent outlets on dual-socket wall plates. I've found the basic energy notifications helpful for identifying when appliances are left running unnecessarily, though don't expect granular wattage readings or historical data.

The limitation is clear: if you want detailed consumption analytics or precise energy tracking, you'll need to look elsewhere. However, for casual users already invested in the Amazon ecosystem who simply want energy awareness alerts and convenient voice control, this plug performs admirably. It's perfect for controlling lamps, coffee makers, or holiday decorations with occasional energy insights, but serious energy monitoring enthusiasts will find it lacking in depth and detail.

Emporia Vue Smart Plug – Best for Analytics

Energy data enthusiasts will find their match in the Emporia Vue Smart Plug, which delivers professional-grade monitoring that rivals dedicated energy meters. The analytics depth is exceptional—detailed historical usage graphs, precise cost tracking with customizable electricity rates, and integration with Emporia's whole-home energy monitoring ecosystem.

I've been particularly impressed with the data accuracy and the ability to track long-term trends for individual appliances. The cost tracking feature has proven invaluable for calculating the true operating costs of various devices, helping justify energy-efficient upgrades. If you're already using Emporia's Vue whole-home monitor, this plug seamlessly integrates to provide device-specific data within your comprehensive energy picture.

The major limitation is ecosystem dependency—you'll need the separate Emporia app rather than controlling through Alexa or Google Assistant. For energy analysts and efficiency enthusiasts, this trade-off is worthwhile for the superior data quality and analytical tools. However, casual users seeking simple voice control will find the separate app requirement inconvenient. This plug excels for users who prioritize detailed energy analytics over smart home integration convenience.

## Eve Energy Smart Plug by Elgato

The Eve Energy stands out with Thread connectivity, delivering faster response times and creating a robust mesh network. I've found its energy monitoring to be exceptionally accurate, with detailed consumption data displayed beautifully in Apple's Home app. The local processing means your data never leaves your network, addressing privacy concerns. However, this Apple-exclusive approach limits its appeal. If you're invested in HomeKit, this plug offers premium performance with seamless integration that feels native to iOS.

## Treatlife Smart Plug with Energy Monitoring

For the price, Treatlife delivers impressive functionality. The app provides real-time power consumption with clear graphs showing daily and monthly usage. Voice commands work reliably with both Alexa and Google Assistant. While the interface isn't as polished as premium options, it gets the job done effectively. Setup was straightforward, and the energy monitoring accuracy surprised me for such an affordable device. It's perfect for users wanting to monitor multiple devices without breaking the bank.

## Gosund Smart Plug EP2

The Gosund EP2 proves you don't need to spend much for basic energy monitoring. Despite its budget price, it provides comprehensive usage reports and integrates well with the Smart Life ecosystem. The compact design doesn't block adjacent outlets, and the LED status indicator is helpful for troubleshooting. While energy accuracy can be questionable with very low-power devices (under 5 watts), it performs admirably with typical household appliances. For whole-home monitoring on a shoestring budget, it's hard to beat.

## Enbrighten Z-Wave Plus Smart Plug by Jasco

The Enbrighten plug excels in Z-Wave networks, offering rock-solid reliability and professional-grade energy monitoring. Its mesh networking strengthens your entire Z-Wave system while providing utility-grade measurement accuracy. Integration with SmartThings and Hubitat is flawless, and the build quality feels premium. The main drawback is requiring a separate Z-Wave hub, increasing costs. However, for existing Z-Wave users or those building robust smart home networks, this plug delivers enterprise-level performance and reliability that WiFi alternatives struggle to match.
