Read out electricity meter GH305 by RaPi

My dream is to read out a electricity meter to RasperyPi. So far I failed

I am Using an Hichi IR Wifi TYP: HB0016 on the electricity meter. The Hichi is set up in the wlan. The device is reading out the total amount and if it is active the KW consuption.
All can by using the IP of the Tasmota.

MQTT is installed on the RaPi and a user is set up.
MQTT information is set up in the Tasmota.

The instance app “Tasmota” is installed but the measurement device can not be found.

Can somebody help with what I am missing? What do I need to do to get the device running and the data stored?

Thanks for the help in advance.
Best regards
Jordy
