Powerpal is significantly more accurate than clamp style monitors!
As Powerpal transmits the data logged by your utility energy meter the usage data reported in the app is very accurate - our users typically report logged usage to be within 99% of utility meter reads.
Please note however that while every effort has been made to ensure energy costs reported in the Powerpal app are accurate, the data from Powerpal (or any home energy monitor) is not a replacement for your electricity bill.
Additional fees, charges, discounts or rebates may be applied by your retailer that could cause your actual energy costs to vary from those reported by the Powerpal app.
