Help with setting up Waldbeck Huygens weather station #146

Closed jdukat closed 6 months ago

jdukat commented 6 months ago

Hi, I'm trying to make sense from this: https://github.com/matthias-bs/BresserWeatherSensorReceiver/issues/41 and from this: https://github.com/matthias-bs/BresserWeatherSensorReceiver/issues/44

The latter I really don't understand :) I'm using an USB SDR stick like this one: https://www.aliexpress.com/item/1005001815260665.html

The weather station seem to be a variant of Sainlogic WS3500 or other Ecowitt device, but I'm completely new to rtl_433 and after hours of staring at various parameters, I can't figure out what to do next.

Here's what I've found:

rtl_433 -f 868.3M -vvv returns:

One more maybe useful output that I grabbed based on #1750

rtl_433 -f 868.3M -R 0 -X 'n=name,m=FSK_PCM,s=1,l=1,r=1024'

Returns such packets every 16 seconds, so it is likely the weather station output, but does a proper decoder exist for it?

One more datapoint - I read the ecowitt data uploaded over http, it reports: freq=868M model=WS2900_V2.02.01

And the ecowitt app shows the device as EasyWeatherPro v5.1.5

matthias-bs commented 6 months ago

Hi,

in your first log, you have

ambientweather_whx_decode: WH31E/WH40 detected, buffer is 198 bits length
ambientweather_whx_decode: unknown message type 12 (expected 0x30/0x40/0x68)

That means the preample was already matching.

You could try to modify https://github.com/merbanan/rtl_433/blob/master/src/devices/ambientweather_wh31e.c (e.g. by adding your message type) and see if can decode any data fields.

This is issue should better be placed in the rtl_433 project, though.

If you get it working in rtl_433, it might be possible to port the decoder to BresserWeatherSensorReceiver. This depends on the required radio parameters.

How about this:

Ah, honestly I intended to submit this for rtl_433. Not sure when I changed the project, probably while searching for other sources where I could find anything about this device :)

Looked into ambientweather_wh31e.c, but this seems to be an accidental match of the preamble, or the protocol has diverged very significantly. When looking for logs from this decoder only, the message type changes and the buffer size changes (and is longer than max 18 bytes decoded for the longest recognized message).

rtl_433 -f 868.3M -vv -R 113 outputs: ambientweather_whx_decode: WH31E/WH40 detected, buffer is 207 bits length ambientweather_whx_decode: unknown message type 24 (expected 0x30/0x40/0x68) ambientweather_whx_decode: WH31E/WH40 detected, buffer is 216 bits length ambientweather_whx_decode: unknown message type 24 (expected 0x30/0x40/0x68) ambientweather_whx_decode: WH31E/WH40 detected, buffer is 211 bits length ambientweather_whx_decode: unknown message type 24 (expected 0x30/0x40/0x68) ambientweather_whx_decode: WH31E/WH40 detected, buffer is 216 bits length ambientweather_whx_decode: unknown message type 12 (expected 0x30/0x40/0x68) ambientweather_whx_decode: WH31E/WH40 detected, buffer is 212 bits length ambientweather_whx_decode: unknown message type 12 (expected 0x30/0x40/0x68) ambientweather_whx_decode: WH31E/WH40 detected, buffer is 212 bits length ambientweather_whx_decode: unknown message type 12 (expected 0x30/0x40/0x68) ambientweather_whx_decode: WH31E/WH40 detected, buffer is 209 bits length ambientweather_whx_decode: unknown message type 24 (expected 0x30/0x40/0x68) ambientweather_whx_decode: WH31E/WH40 detected, buffer is 210 bits length ambientweather_whx_decode: unknown message type 12 (expected 0x30/0x40/0x68) ambientweather_whx_decode: WH31E/WH40 detected, buffer is 216 bits length ambientweather_whx_decode: unknown message type 24 (expected 0x30/0x40/0x68) ambientweather_whx_decode: WH31E/WH40 detected, buffer is 210 bits length ambientweather_whx_decode: unknown message type 12 (expected 0x30/0x40/0x68) ambientweather_whx_decode: WH31E/WH40 detected, buffer is 210 bits length ambientweather_whx_decode: unknown message type 12 (expected 0x30/0x40/0x68) ambientweather_whx_decode: WH31E/WH40 detected, buffer is 213 bits length ambientweather_whx_decode: unknown message type 24 (expected 0x30/0x40/0x68) ambientweather_whx_decode: WH31E/WH40 detected, buffer is 215 bits length ambientweather_whx_decode: unknown message type 11 (expected 0x30/0x40/0x68) ambientweather_whx_decode: WH31E/WH40 detected, buffer is 211 bits length ambientweather_whx_decode: unknown message type 22 (expected 0x30/0x40/0x68) ambientweather_whx_decode: WH31E/WH40 detected, buffer is 215 bits length ambientweather_whx_decode: unknown message type 24 (expected 0x30/0x40/0x68) ambientweather_whx_decode: WH31E/WH40 detected, buffer is 210 bits length ambientweather_whx_decode: unknown message type 12 (expected 0x30/0x40/0x68) ambientweather_whx_decode: WH31E/WH40 detected, buffer is 209 bits length ambientweather_whx_decode: unknown message type 24 (expected 0x30/0x40/0x68)

This seems more probable, as wh24 - device [78] is also referenced in https://github.com/matthias-bs/BresserWeatherSensorReceiver/issues/41, and when I was buying this weather station, I got some clues that it is another brand of Sainlogic WS3500, which was expected to work seamlessly (as mentioned on Home assistant forums).

But scanning with -R 78 shows all kind of problems:

Looking into the comment in fineoffset.c:

The sensor sends a package each ~16 s with a width of ~11 ms. The bits are PCM modulated with Frequency Shift Keying.

Example:

         [00] {196} d5 55 55 55 55 16 ea 12 5f 85 71 03 27 04 01 00 25 00 00 80 00 00 47 83 9

    Payload:                              FF II DD VT TT HH WW GG RR RR UU UU LL LL LL CC BB

This seems to make sense, as my device also sends packets every ~16 sec and if you look at the next byte after the preamble, it's 12 or 24, and in the log above the 12 and 24 are the most frequent msg unrecognized by wh31e decoder.

jdukat commented 6 months ago

Can it be that my radio is receiving a lot of noise? The packets looks like they should make sense:

Fineoffset_WH24: Raw: 24 09 67 82 70 32 00 00 00 03 00 00 00 00 72 04 56 @ bit_offset [59]
Fineoffset_WH24: Checksum error: fd 31

24 is expected, but sometimes it is 12, sometimes 22 - look like single bit errors - bits shifted by 1 position Next byte 09 - on my station there is a sticker saying 'sensor id 09' so it makes perfect sense, but sometimes it reads 04 instead

matthias-bs commented 6 months ago

Could be noise or overloading the receiver if it is too close to the transmitter.

jdukat commented 6 months ago

Moving things around doesn't help, same problem. I give up. I hoped to connect this weather station directly to Home Assistant and not using the head unit at all (use rtl_433 and send packets to mqtt) but I switched to Ecowitt integration and it works out of the box over local wifi. Feel free to close this issue, I will not debug it further.
