Your BitBench looks good. I've updated the link to invert all bits and use PRE:hhh ID?:hh hh hh TEMP_C:12d HUMID:8d RAIN:12d WIND_KM:8d 4d 4d 4d 1b 7b
All fields align nicely to bytes. For wind direction I would expect 4 bit for 16 cardinal directions or 9 (12?) bits for a full degrees value. But also 8 bits for a checksum at the end. We have 13 bits left, so maybe 5+8? But I can't spot the wind dir.
Can you get readings for at least the 16 cardinal directions? Or even better slowly turn the direction indicator to see if there is a field at the end that changes slowly? Once we figure that out I'll add the device support.
Or perhaps keep the direction fixed (due north should give all 0's) and let other values change so we can see which bits at the end stay the same.
@pinolec Are you still working on this?
Hi,
I try to crack this device: https://www.mediaexpert.pl/dom-i-ogrod/do-domu/stacje-pogodowe-i-termometry/stacja-pogody-bioterm-270208#reviews also, this seems to be the same weather station: https://it.aliexpress.com/item/32830480338.html This is probably available under many different brands and model numbers.
By default it is recognised as:
cu8.zip
I used
rtl_433 -R -86 -X 'n=Smoke-GS558,m=OOK_PWM,s=450,l=980,g=1499,r=9000'
to collected some data available here: BitBench
This is what I determined: ID?:hhhhhh hhh TEMP_C:~12d b HUMID:~7d RAIN_TOTAL:~12d 3d WIND_KM:~5d 20b
There probably should be somewhere sign bit for temperature but I had no chance to test it yet. I couldn't find the wind direction and Pressure.
Please advise what to do next.
Kind regards, Piotr
