Energy Totals Incorrect - Arlec PC399HA Smart Energy Plug

[smithy2167]

PROBLEM DESCRIPTION

A clear and concise description of what the problem is.
The Energy Totals displayed and in MQTT messages are incorrect - they are about 1/6 what they should be.
The Voltage, Current and Power readings have been calibrated and are all correct.
First noticed when running version 8.4.0.3
Downgrading to version 8.4.0 fixed the problem.

Similar misbehaviour experienced on GoSund SP111 smart plugs. Downgrade to 8.4.0 fixed it.

[coolman111]

Similar misbehaviour experienced also with Tasmota 8.5.0 on Gosund SP111 Hardware Version 1.1.
The energy values in kWh should be about 15x greater than displayed.
The other readings (Volt, Watt, Ampere, Factor=1.00) seem to be correct.
Everything had been calibrated before updating from Tasmota 8.2.0 to 8.5.0.
Downgrading to 8.4.0 solved the problem.
Theo, I hope this information could be helpful.

Note that this was tested with power levels of 350W, 2200W and 2450W so is assumed not to be related to low power level issues.

I just reverted the change #9160 locally and I see the counters start to work again. As the above mentionend devices use the same code I'm quite sure this is the cause of your issues too.

Fix has been integrated in latest release v8.5.0 binary downloads

[coolman111]

Confirmation: I got the last release 8.5.0 Build 2020.09.09 11:47:14, tested and works 100% perfectly on Gosund SP111.
Even better than before 8.4. The Energy kWh display is only +1.3% different to my old CONRAD Energy Meter EKM265.
At 8.2.0 the difference was more than +10%. I did not make any change in calibration.
Congratulations, excellent fix.

Ich kann auch bestätigen dass mit der aktuellsten Firmware das Problem beseitigt ist. Getestet auf einer Gosund SP111. Werte werden korrekt berechnet :)

I can also confirm that with the latest firmware the problem is solved. Tested on a Gosund SP111. Values are calculated correctly :)
