Tasmota: Voltage/Current measurands are swapped

[homber]

Describe the bug

Beim Auslesen der Daten von einem Tasmota HW-655 PZEM mit 3 Phasen als meter, werden die Daten Strom und Spannung (Current Voltage ) vertauscht.

Steps to reproduce

1.evcc -c evcc.yaml -l trace meter

...

What type of operating system or environment does evcc run on?

Linux

External automation

• I have made sure that no external automation like HomeAssistant or Node-RED is active or accessing any of the mentioned devices when this issue occurs.

Nightly build

• I have verified that the issue is reproducible with the latest nightly build

Version

evcc version 0.200.1
