What Customers Say
Clever, Accurate, and Great for Sub-Metering
"We installed Voltaware to monitor energy usage in our garden annexe, and it does the job perfectly - tracking both total consumption and individual appliances. While setup took a bit of care (especially with WiFi), the included instructions were excellent and easy to follow. It's not exactly plug-and-play, but if you follow the steps, it’s straightforward. A very clever device - even better than I expected."
Chris
A Big Step Up from Plug-in Monitors
"I returned a plug-in energy monitor because it only tracked one device and lost data when unplugged. Voltaware is a far better solution — more powerful, and likely to pay for itself in 6 months. The app has a bit of a learning curve, but it’s already helping me identify background consumption and hidden energy drains. I’ve reduced standby usage from 150W to just 18W. It’s insightful, detailed, and genuinely useful for cutting waste."
Steve H
Great App, Accurate Insights Over Time
"I’ve been using the Voltaware sensor in my flat for four months. Setup was easy, and while accuracy improved over time, it’s now very impressive. The updated app is excellent — offering clear real-time and historical energy data with appliance-level insights. A very good tool for understanding home energy use."
