<blockquote><div class="quotetitle">Quote from <a class="profile-link highlight-admin" href="#">Christian Nissen</a> on 2022-01-07, 11:42</div>See my edited post above Nax. And my blogposting <a href="https://www.tuyausersblog.com/2021/02/03/wrong-calculation-of-power-from-smartplug/">Calculation Error of power from NEDIS SmartPlug - Blog and forum for Tuya-users (tuyausersblog.com)</a> is discussing the problem.

Nedis support has not been very helpful trying to explain it with that the power calculated from voltage x current is the reactive power (especially motors drives the voltage phase and current phase out of sync) and the shown wattage-power is nonreactive part of the energy consumption. Which is what the power company SHOULD charge You for...

The explanation is however how the plug SHOULD work, but does not, I have been testing it with purely resistive loads like a heater element that does not drive voltage and current out of phase, and still there is a difference.

Hopefully Tuya´s support will clearify this better and perhaps make an app or firmware change to fix the problem in the future.</blockquote><br>
