Finding Parameters for Tuya Bidirectional 3 phase Energy Meter with CB3S Chip

I bought this device:

Tuya WiFi ZigBee dreiphasige bidirektionale Zweiwege-Energie kWh Meter Monitor Wattmeter Unterstützung Modbus RTU 3*85/190V oder 230/400VAC

It is what we call in Germany eierlegende Wollmilchsau. It has display, pulse, Modbus, and Tuya WLAN.

WLAN Chip is CB3S. Reading good but only result from flasher was baudrate at 9600 no other data found.

Flashing also without problem - but now how to find out all the parameters?

SO I entered the parameters from here:
https://www.elektroda.com/rtvforum/topic4056617.html

at least the deviceshows no error now anymore in the display and the wlan signal is displayed in the display as well as the wlan connection is on.
However in the webinterface still no values.

Why does it have "Zigbee" in title while CB3S is clearly a WiFi (not Zigbee) module?

Here is TuyaMCU guide: https://www.elektroda.com/rtvforum/topic4038151.html
This covers most of the setup process of such devices,

If you already flashed it, I would start with tuyaMcu_sendQueryState

Hi,
they sell 2 different devices, one with WiFi one with Zigbee - that's my guess.

Thanks for the hint, I will try.

I saved the original firmware. How do I flash this one back?

You can use restore backup option from our flasher:

It may not be necessary to flash it back, I would start with querying the state.
