Support for the WH57 lightning sensor

[Luis Balbinot]

Hello,

I just got a WH57 lighting sensor (Fine Offset/Ecowitt) and I'm starting to work on the decoder. Is anyone else working on this? Any information/documentation would be great. I have nothing but the captures.

The modern FineOffset protocols are FSK PCM with AA... preamble and 2DD4 sync word. That should show the data bytes nicely.

This could work:

rtl_433 -R 0 -X 'n=WH57,m=FSK_PCM,s=60,l=60,r=1800,preamble=AA2DD4'

See also e.g. https://github.com/merbanan/rtl_433/blob/master/src/devices/fineoffset.c

Open an issue "Add support for FineOffset WH57 lighting sensor" with details.

Sorry if I am late to the table or if you are the author...

WH57  is equivalent to WH31L  which is protocol  190
