Smartmeter Landis+Gyr E450

[speedymk1]

Like in the title written I use an Landis+Gyr E450 Smartmeter.

I use the prebuild Tasmota version: Tasmota 14.4.1 (ESP32-C3 ottelo.jimdo.de) by Theo Arends

The script:

>D
>B
smlj=0
=>sensor53 r
>R
smlj=0
>S
if upsecs>22
then
smlj|=1
endif
>M 1

But I get on the console only:

21:07:07.303 :>30 32

or

So, why dosn't it work?
Is there something wrong in Tasmota with the E450 and the encrypted data?
I think, that the decrypting doesn't really work, bekause if I deaktivate the encryption by deleting the
1,=so4,******MY KEY****** Line, I get data like the provider told me in an example.

Has nobody an solution?

For all who have the same problem like I had, it took me really a lot of time...

Important:
Run the debug mode and get something like this:
20:15:11.946 SML: decrypted block: 50 bytes
20:15:11.946 :>02 0b 12 00 e7 12 00 ea.....
from here you need the 020B12 and you have to use it like an prefix.

Example line:
1,020B12x2UUuu@20,Spannung L1,V,V_L1,0
1...first meter
020B12...the prefix from the debug mode
x2UUuu...see the documentation; someone in the forum here use other numbers like me (insteat of 2 he use 1).
But if I use the same numbers like he, my power have over 1000 V, so I have to search it manually by try and error.

Additional the script have to be formatted in ANSI code.
