Maddalena Arrow Wan 2 (module RF for water meter) - which rtl_433 parameters ?

[stan1m]

Hello,
I am trying to read information from Arrow Wan 2 with these parameters : rtl_433 -f 868.95M -s 1200k (protocol id 104).
But I have no result (I can read devices on 433 mhz with only "rtl_433" so there is no hardware or config issue).
I use usb stick with fc0012 chip (on raspberry pi). The distance sender-receiver is about 15 meters.
Thanks for your help.

Try with adding -Y autolevel -M level -M noise and also -v or -vv or selectivly -R 104:vv to see more messages.

Thanks a lot ! With your additionnal parameters I get now a few lines for Wireless M-Bus, Mode C&T, 100kbps.
I suppose the device (arrow wan 2) is not fully supported yet, because the lines are not readable (different lenghts of codes, unformatted).
How could I get a comprehensible result ?

New defaults active, use "-Y classic -s 250k" if you need the old defaults
