Read values from Smart Meter ITRON 3.HZ with ESP8266

[Tom0815-newbie]

Hello everybody.

I´m really a new on this topic.
But as already mentioned in the description, I´m trying to receive actual values from ITRON 3.HZ smart meter.
I´m using an ESP8266 nodemcu with tsop4838 ir receiver.
Tasmota is already flashed on the device and it shows me the webui.
To flash the device with tasmota I used visual studio code.
I implemented the use SML script in the user_config_override.h as described on the page.

Unfortunately I dont see any values on the tasmota webui:

If I use sensor53 d1, I can see data coming out of the smart meter.
They all start with 77 and a lot of other numbers.
All starting with 77 XX XX XX ....

This is my script, which I copied from the smart meter tasmota page:

I have already entered my PIN in the smart meter.
And the Inf is switched to ON.
Unfortunately both did not help.

What am I doing wrong?
