Hello almerindo,
I'm sorry, but what you want to do - it will not work. According to
https://www.diehl.com/metering/en/products-services/system-software/system-software-components/izar-rc-i-r4-at/ your device is sending in R-mode (R3 or R4?) WmBus mode, which is not implemented now.
FYI: Appendix of https://www.ti.com.cn/cn/lit/an/swra423/swra423.pdf contains a nice summary of all possible OMS (WmBus) modes.

Hi! I tried with the right frequency in 434.47 MHz (R3 mode) and It is working now!
rtl_sdr -f 434.47M -s 1600000 - 2>/dev/null | ./build/rtl_wmbus
The output:
T1;1;1;2022-08-23 23:20:57.000;127;162;0106741C;0x1344304c1c7406018800a04114001300aa3afd3c

I used the wmbusmeters and now I'm getting all wattermeter of my neighbors :-D
wmbusmeters --debug --t1 rtlwmbus:434.47M
Output:

Thanks !

ΠΠΊ, I thought that this water meter would be sending consumption values in R Mode, which is currently not supported by rtl-wmbus. Bit it was a "usual" T1 Mode. Sorry for having put some irritations into it ;)
