I just published v1.7.2 to the app store (test environment): Aqara App for Homey | Homey
This version should fix (by adding fall back options) the power and energy reporting for the Aqara switches / plugs.
If power and energy is not reported properly, please send an app diagnostics report (settings > apps > Aqara > send diagnostics report) and share a device interview result (Homey Developer Tools > interview devices)
