Wireless M-Bus - How to set the sample rate?

[eporsche]

Current Situation

In the descirption of the pulse slicer the -s flag is set for rtl_433 -> Wireless M-Bus Mode C&T, 100kbps (-f 868.95M -s 1200k) However I am not sure how to set it for the rtl_433_ESP - is there a build flag I can use for this purpose?

Logs

N: Send on /RTL_433toMQTT/undecoded signal msg {"model":"undecoded signal","protocol":"signal parsing failed","duration":1996,"rssi":-98,"pulses":18}

Due to the usage of hardware based signal demodulation the sample rate configuration option is not required. Have you enabled FSK mode ?

[-s ] Set sample rate (default: 250000 Hz)

Ok thx - good to know! Well I set this '-DOOK_MODULATION=false' build flag and the logs showed to me that its trying to decode the signal with the Wireless M-Bus Mode C driver. I did try this project https://github.com/SzczepanLeon/esphome-components and I start getting the telegrams now - not really sure what I am doing wrong, I guess it has something to do with the underlying wmbusmeter vs rtl_433 decoder libraries.

I need to run another test with another position in the house. I have some believe that this is/was the issue here!
