Help needed

Hi @ZeWaren

I have tagged you in the wmbusmeters github as well and trying here, maybe you will see this and guide me.

I used this tutorial and setup: https://github.com/zibous/ha-watermeter/blob/master/docs/wmbusmeters-with-rtl-sdr.md (raspberry 4 instead of pi zero)

I have this meter:
ARIES IS Water meter
https://www.diehl.com/metering/en/products-solutions/products-services/water-metering/aries-is-at/
IZAR integrated 868 MHz and 434 MHz radio, PRIOS protocol

When running:
rtl_sdr -f 868.625M -s 1600000 - 2>/dev/null | rtl_wmbus -s
I get a lot of:

I was comparing the data what I have with what you posted on your blog:

`Decoding a Sappel frame
Let’s look at a full frame received by the antenna of my circuit:

01010101010101010101010101010101010101 0000111101b + 1944304CC697D720D401E2E6A213120013184587BD6EB979401E8B407096h
`

I have as a frame (filtered the ones with 19 44 like this

rtl_sdr -f 868.625M -s 1600000 - 2>/dev/null | rtl_wmbus -s
T1;1;1;2023-09-21 19:32:21.000;101;127;2150A9FA;0x1944304cfaa950211404a2231400134a2c75e61a25bb0d891f7d

If I would compare what is obvious to my eyes:

Your example: 1944304CC697D720D401E2E6A213120013184587BD6EB979401E8B4
Mine: 1944304cfaa950211404a2231400134a2c75e61a25bb0d891f7d

I am several chars less

Can you help me understand what is wrong?
