Likely causes

  • Load too small for the metering range
  • Firmware without metering for that model
  • App unit or tariff settings not configured
  • Local safety limit shown instead of a measurement
  • Hardware metering fault

Quick checks

  • Connect a larger known load and watch the reading
  • Check the model specification for metering
  • Review units and tariff settings
  • Update firmware

Step-by-step fix

1

Test with a load the meter is designed for

2

Confirm the model actually meters power

3

Configure units and tariff in the app

4

Update firmware and re-check

5

If the reading never changes, request a warranty replacement
