10 Best Home Energy Monitor 2025 in the UK

The LOWENERGIE UK Plug-in Power Meter Energy Monitor is a device designed to track the power consumption of household appliances, which can be useful for individuals looking to manage and reduce their energy costs. One of its standout features is its ability to calculate and display cumulative energy usage in kilowatt-hours (KWhr), along with the associated cost, which can be customized according to your local electricity rates. This makes it easy to understand which appliances are consuming the most power and could help in making informed decisions to lower energy bills.

The monitor's backlit LCD display is a user-friendly feature, providing clear readings in various lighting conditions. An overload warning function adds a layer of safety by alerting users when the power or current exceeds set limits.

However, the product does have some limitations. The lack of compatibility with other smart home systems might be a drawback for tech-savvy users looking for integration with broader smart home ecosystems. Additionally, while it provides cumulative usage data, the absence of advanced real-time monitoring or historical data tracking through a companion app means users won't have access to more detailed analytics that some other monitors might offer.

Installation is straightforward, simply plugging into a socket, making it accessible for those with limited technical skills. There's no information on alerts and notifications beyond the overload alarm, so users looking for more comprehensive alert systems may find this lacking.

This energy monitor is suitable for users prioritizing simplicity and straightforward energy monitoring over complex integrations and detailed analytics. It's a practical choice for those who need a reliable, easy-to-read device to keep track of energy use and costs without needing advanced smart home functionalities.

The Power Meter Plug Energy Monitor is a practical tool for those looking to track their home energy usage. It offers multiple measurement functions, including voltage, current, and energy consumption, which are essential for accurate home energy monitoring. The inclusion of a visually appealing backlight LCD ensures that data is easy to read at any time of day, with a flexible 180° viewing angle.

The device has a user-friendly installation process, as it simply plugs into a standard outlet. It also includes a reset tool, which can be a handy feature for users who need to reset their settings without hassle. This monitor is corded electric, eliminating the need for batteries, a convenient feature for continuous use.

On the downside, the data accuracy depends on the power usage, as the 'day' and 'time' tracking only activates for devices that consume more than 0.5 watts. This limitation may not be ideal for monitoring devices in standby mode. Additionally, users must manually set the overload threshold from the default 3680W to 2900W to ensure the overload function properly alerts them, which could be cumbersome for some.

The monitor supports real-time monitoring and stores data automatically, preventing loss during power outages, although accessing historical data might require extra steps due to the manual data clearing process. The user interface might be challenging for those not familiar with similar devices, as settings require long presses and simultaneous button actions.

In terms of compatibility, it fits UK power outlets and is certified, providing peace of mind regarding safety standards. However, it may not be suitable for regions using different plug types. With a solid customer rating of 4.3 and a two-year warranty, it represents a reliable choice for UK users focused on reducing energy bills and monitoring household energy use efficiently.

The OWON 3 Phase WiFi Smart Home Energy Monitor offers several features that make it a valuable tool for managing and conserving energy in a home. It provides real-time monitoring, requiring a 2.4 GHz WiFi connection, and delivers energy data every two seconds with an accuracy of +2%, which is commendable for those who seek precise energy usage information. This monitor is compatible with various appliances, thanks to its three 80A sensors, making it suitable for monitoring high-energy devices like air conditioners and water heaters. The product's compatibility with the 'SmartLife' app enhances its user interface by allowing convenient access and control via smartphones. Installation is relatively straightforward, as it is lightweight and involves clamping onto power cables, although it is recommended that a qualified professional handle the installation to ensure safety.

Despite its strengths, the product does have some limitations. The requirement for a 2.4 GHz WiFi might not be suitable for all households, as some might prefer or use 5 GHz networks. Those who need precise energy monitoring and want to integrate their home appliances into a smart energy management system will find this product useful. However, those who are less comfortable with technology or require assured long-term software support may want to consider these aspects carefully. The product is ranked 47th in Power Monitors, indicating decent popularity and customer satisfaction, but it's essential to weigh both its capabilities and limitations before making a purchase.
