@dclaar we need some RAW records first
I ran it in RAW while rtl_433 showed several packets--and a bunch of unknown stuff--go by. The RAW files seem very short, with just 1 chunk of RAW_Data. rtl433_output.txt corresponds to RAW-20240102-184902.sub.txt
RAW files you recorded are useless. Looks like you were using incorrect modulation settings: rtl433 is suggesting FSK
Ah, OK, I don't see an option for FSK. Maybe one of the FM settings?
This was kind of why I was hoping that someone had written a doc on "this is how you do this" so I wouldn't waste people's time. Here's one with each FM setting. RAW-20240102-192241.sub.txt RAW-20240102-192149.sub.txt
yes FSK is subtype of FM
Looks like default config is not going to work or this record was done incorrectly.
Does rtl433 shows you anything when you replay it from flipper?
any updates?
I'm stymied and frustrated. When I put the flipper right next to the transmitter, the RSSI indicator doesn't even twitch. There's no indication that it is receiving anything. When I replay the recording, nothing happens. But the unit is clearly transmitting: rtl-433 sees it. So I don't know where to go from here.
Just found this topic - I've got a WS-5000 I can try some captures on.
I'd like to see support for this protocol.
I know that this is open source, and I'm happy to contribute, but it's a little difficult figuring out how to start. Not the github stuff, or the tool chain, but more the structure of the files, what's a "SubGhzBlockConst", etc. I'm trying to wrap my head around the protocol files--and on translating rtl_433 to flipper--but I haven't found a lot of documentation yet.
I have an Ambient Weather 2902, and the sending unit identifies as "fineoffset-WH24" in rtl_433:
It's at 915mhz. It's different than the current ambient_weather.c:
This protocol was added to rtl_433 in 2018, discussion of the signal is here.
The format is described as: "The sensor sends a package each ~16 s with a width of ~11 ms. The bits are PCM modulated with Frequency Shift Keying"
Thanks!
