rtl_433 🚀 - Add Protocol Weather Station Bresser 6in1

Hello,

Bresser 6in1 was added yesterday in rtl433_tests.
https://github.com/merbanan/rtl_433_tests/tree/master/tests/bresser_6in1

How will the protocol be added in rtl_433?

Need some information? If so why ?

Or do we have to wait a while to add other protocols in the update?

I am ready to do the required manipulations if necessary.

Thanks
Seb

Can you run rtl_433 -s 1M -X 'n=Bresser-6in1,m=FSK_PCM,s=100,l=100,r=2000'
and send us:

Try out the PR #1225 for Temp and Hum so far.

I do not understand.

Do you have the information you were looking for or do you want something else?

Do you want me to enter data in BITCHEN format?

Thanks,

All is well. The BitBench is just to play and understand.

hello

Little question

Will the Bresser 6in1 protocol add to the list of protocols so that I can use the weather station with weewx.

Thanks

f4gqk on 8 Dec 2019

Yes. But it will take some time.

Do you use Windows or Linux? Can you test the code? Use #1225 or download the zip, then compile and run.

zuckschwerdt on 8 Dec 2019

Ok for the developpement . I use Linux on Raspberry. I will test the code.

Thanks

HI,

any news with this device?
Do you need data? How can we help?

BR
Nikos

nkpap on 27 Dec 2019

The solution but it's simple for me.

Would make RTL433 compatible with this weather station so that I can send the data on WEEWX because it is not recognized by the cable.

Thanks

f4gqk on 29 Dec 2019

Hi,

I also need the RTL decoding to feed the WEEWX.

level20peon on 28 Jan 2020

@f4gqk your recent data looks good in a BitBench
Shift by one bit and the expected sync word 2dd4 is visible.

The branch from #1225 does work, yes? We just need to figure out where the wind etc. data is.

We need annotated codes like this:

I am also hoping to get this working for the bresser 5-in-1 model 7002580, which I believe is the same as the 6-in-1

is there any progress on the Bresser 6in1?

The barometric pressure is likly not measured remote. Haven't spotted Wind speed or rain yet. Can you perhaps add more codes with interesting readings for wind and rain (paste here or link to a BitBench)?
I'll update the decoder later today

zuckschwerdt on 20 Sep 2020

Rain is likely measured in "bucket tips" and accumulated, we are looking for a field with some value that increases when rain is reported.

Ideally to find the missing values you need to get the sensor indoors then tip the rain bucket by hand and observe which number in the codes increases. Slowly add single bucket tips to confirm. Maybe then pour a measured amount of water in and see how much water is one bucket tip or compare a counted number of tips to the console readout.
For wind speed maybe rotate the sensor a different fixed speeds and observe where there is a matching number in the codes. I expect there to be two fields: gust (maximum) speed and average speed.

zuckschwerdt on 22 Sep 2020

Still trying to learn how to read the code on BitBench.
But like an earlyer comment will use this for my weewx

RebeckaJohansson on 23 Sep 2020

For weewx there is an extension and Bob that decode this has this information in py file there is some codes to read in this .py file

[https://github.com/BobAtchley/weewx-ws6in1/blob/master/bin/user/ws6in1.py ] (https://github.com/BobAtchley/weewx-ws6in1/blob/master/bin/user/ws6in1.py)

RebeckaJohansson on 27 Sep 2020

I have find wind speed and wind gust in the code.
I have dubblecheck it to.

I have ventus w835 6in1 and is a copy of Bresser 6in1

In bitbench i used:

SYNC16h CHK?8h8h ID?8h8h8h8h8h SOME VALUE? 8h8h8h WIND DIR 8h4h ?4h TEMP8h.4h ?4h HUM8h RAIN?8h WIND SPEED / GUST 8h 8h 8h

The result is in this BitBench.

RebeckaJohansson on 28 Sep 2020

Thanks! I'Ve updated your format string to SYNC16h DIGEST:8h8h ID?8h8h8h8h FLAGS:4h BATT:1b CH:3d WSPEED:~8h~4h ~4h~8h WDIR 8h.4h ?4h TEMP8h.4h ?4h HUM8h UV/RAIN?8h8h CHKSUM:8h TRAILER:8h.
"Trailer" is invalid, the 6-in-1 message is 18 bytes long, the last byte is a checksum, the last 16-bit before the checksum is known to be UV (and maybe rain?).

The wind speed is in byte 7-9 but inverted! So we known most of the fields now :)

I updated for what is correct for my code and i find specifik WSPEED and WGUST and added it i bitbench

The rain or uv is hard for me i have no uv recorded today because of dark and rainy weather in sweden so my uv is only 0 my rain today is 0,5 in mm as rain rate so i cant se if its uv or rain value because i only have 0 in the code or 0,1

But i added this in bitbench and synced it and for my code this is correct for me

RebeckaJohansson on 28 Sep 2020

I think it's WGUST:~8h,~4h / WSPEED ~4h,~8h not WSPEED:~8h,~4h / WGUST ~4h,~8h. Otherwise looks good!
You can try #1225 which now includes these fields.

I tested it but the wind value goes wrong and for me the windspeed calculate gust and wind gust calculate windspeed 🤔

RebeckaJohansson on 28 Sep 2020

Strange. Gust is the bigger value and Average Speed the smaller one, right? Like in:

and

zuckschwerdt on 28 Sep 2020

Strange. In bitbench for my codeing for Ventus 6in1 the value and wind check is avg speed first and then gust 🤔

I can check tomorrow again.
But before i tested when i touch the wind pointer outside and same time decode it gave me the value like i wrote in bitbench 1,1 wspeed and 9,3 wgust in m/s mabey i need to change something in the bitbench code.

RebeckaJohansson on 28 Sep 2020

Check my codeing here, if i change to gust first and then avg speed it gives wrong value for me.

RebeckaJohansson on 28 Sep 2020

I see. the digits in the transmission are in a strange order: if you see 022 900 you need to read that as 02,2 and 00,9 -- that's what the decoder currently does.

Ohh i see, I was confused at first but now i understand how i need to read it. So i change it to this now like what you described before with the wind.

I hope this is right now :)

The protocol named "6-in-1" (18 bytes data, digest+checksum) is used by multiple sensors. At least:

new 5-in-1
6-in-1
7-in-1 indoor
SM60020 Soil moisture

We need to figure out if there are flags in the data indicating the sensor type.
Can everybody please report each of your exact sensor models with the ID from current #1225 output.
ID should be like ID "1880 02c3 18"
Exact model should include the branded name a product code (some longer number) and what type of sensor it is.

You can also analyze the data yourself, there are two different messages, one with temp/hum and one with rain:

bresser_6in1_decode: {144} 83 ae 18 80 02 c3 18 fc 78 fc 29 28 ff ff ff ff 01 cc
bresser_6in1_decode: {144} 5c e4 18 80 02 c3 18 fb ba fc 26 98 11 84 81 ff f0 16
                           ^^^^^digest          ^-.. wind ..-^ ^^^^^^^^ temp/hum or 0xff,rain
                                 ^^^^^^^^^^^^^^ id and flags            ^^^^^ UV or unknown

zuckschwerdt on 29 Sep 2020

I also checked wich stations are 6in1 and those who has same outdata:

Ventus w835
My Ventus w835 has data for
Barometer
Winddir 360°
Windspeed
Windgust
Beaufort
Temp
Hum
Dewpoint
Heatindex
Windchill
UV
Rain with raintipper
Solarpanel/power for battery
And my Ventus transmissions interval:
12 seconds for vind data
24 seconds for temperatur, hum, UV and rain dat

The other station with or close same output is
Youshiko YC9388
Bresser 6in1
Garni 935PC

RebeckaJohansson on 29 Sep 2020

I still figuring out uv and rain

My uv is on 0 now and rainrate is 0 for specific today.
My total rain is 5,8 mm and highest rain rait is 4,1 mm/hour

My id i got in code is 1910084d

RebeckaJohansson on 29 Sep 2020

Hmm i dont know how to find the specifik productcode

I checked my box that my station come with and it only have VENTUS W835 as name and what the station can do. Cant find any other number more then this number from the brand site

(https://www.nshnordic.com/english/products/produkter/ventus/vaderstationer/ventus-professionell-vaderstation-w835-med-pc-mjukvara?AreaID=51&LanguageID=LANG1)

RebeckaJohansson on 29 Sep 2020

Sorry for spamming. Bur i mabey figuring out the last in the code. My rain rate check is 4,1 and the code shows when seperated uv and rain i got 014 in code.

Check my picture. Mabey is right mabey is wrong.

RebeckaJohansson on 29 Sep 2020

It's UV:8h 8h CHK:8h -- your code is too long.
Rain is encoded in the temp/hum field.

with temp/hum 179466 : 17.9 C, 66%
with temp/hum ffedcb : edcb ^ ffff = 1234 123.4 mm

Rain is an accumulated (life time) value, so 441.6 seems to match 440.8, right? UV 1650 is ff0, I'll filter that out with the next update.

Can't see a model indication in the ID though, e.g. we have both

2030 088d 10 : mvdgrift, Wi-Fi Colour Weather Station with 5in1 Sensor, Art.No.: 7002580
1970 0d57 18 : danrhjones, bresser 5-in-1 model 7002580

zuckschwerdt on 1 Oct 2020

Minor correction, the ID reported by my weather station is 2030 088d 18 (instead of 2030 088d 10)

mvdgrift on 1 Oct 2020

The 0/8 seems to be a battery indicator, broken out as battery in the output. The lower bits are shown as channel.
Not sure if 0 or 8 (=1 in the output) means good or bad battery. Watch out for that and let me know.

Thanks. UV (165 = ff01) is already filtered in the updated version now.
Not sure what the data ab01 (=111.0) in the UV field means. It should mean something as the invalid value is ff01 and a valid UV is e.g. 123? (=12.3). But I don't know if a value is missing? ab01 could be 54 (xored with 0xff, like wind and rain) -- but what would 54 be?

My uv index is 0 here. I think something is mabey missing in the code. But i dont know what 🤔

RebeckaJohansson on 7 Oct 2020

You have an UV sensor (which sometimes reads something like 2.3) that should be reading 0.0 but only gives 165 and 111?

zuckschwerdt on 7 Oct 2020

Yes, but my uv has been on 0 many days now because of very bad weather. I know that my ventus has

24 seconds loop for temperatur, hum, uv and rain
12 seconds loop for wind data

I dont know if my solar panel that powers the battery on sensor is the same as battery reading.

But i find this information for my outside sensor and my manual book says that weatherdata reads from outside is:
Temperature, hum, wind, winddirection, rain and uv

My manual in different language it says two models for my ventus

Germany is says model C8488A

If i try to connect it to windows i can see in controlpanel and via device and printers i got name C8488

Hi @m-alzam,

The pressure sensor is part of the base station (not of the remote sensor). That means that the pressure value is not transmitted over the air. And that is the reason why it is not displayed.

Regards,
Marco
