Hi. I'm on my RTL finding the values of a Brasser wireless thermometer (or Brasser-like in protocol, don't really know, it's not my device), but there are 2 recordings for each measurement.
I recorded the signal, it looks uniform to me, 24 repetitions of the signal at regular intervals.
I attach the recorded file (the file, by the way, was recorded one for two recordings)

Looks like a 2 second gap, that will be two sample files, maybe g010 or g012? I think the original has 15 repeats once every minute. Could be some variant with 24 repeats sent twice in succession.

No, both records appear in the temprinal almost instantly. It is unclear why there is such a 2-second difference in the output.
If you identify the file ./rtl_433_64bit_static.exe -w OOK:- g011_433.92M_250k.cu8 then the output gives 2 records.

The period of transmission of readings is 1 m 54 s. It may not be the original Bresser, but some other sensor with a similar coding protocol.
Sometimes readings are even decoded as [87] Generic-Motion in the middle

Ok, interesting. There is a visually continuous transmission of 24 packets but somehow that get broken into 17+7 packets.
Also noteworthy, there is first a sequence of 9 PPM packets, then the 24 PWM. So this is some other sensor which emits two different protocols for compatibility.
