Decoding from Froggit WH6000

[stef LP]

Hello everybody, 

 I ve a new station "Froggit WH6000" and I want to snif from RTL data sensors.

I dont find any docs for this station  and  I dont know  how to intercept data with rtl_433 program

I' ve RTL key : 

Bus 001 Device 004: ID 0ccd:00d3 TerraTec Electronic GmbH

root@Rpi2:/home/pi/WH6000# rtl_sdr -d 0

Found 1 device(s): 0:  Realtek, RTL2838UHIDIR, SN: 00000001

But I dont know How to find frequency / sensors from my new station 

I try  several option like this : 

# rtl_433 -f 868M -s 1024k -X n=WH6000,m=FSK_PwM,s=1,l=1,r=1024

but  nothinhg  match  ! 

(I m newby in rtl sdr   ;) )

Can someone help me ? 

Thanks a  lot

Stephane

If you can't find the signal use CubicSDR or Gqrx to locate it. Note the frequency.

It should be around 868M. Then try

    rtl_433 -f 868M -A

To see if there are transmissions.

Note the "-X ..." suggestion from the analyzer. It should be e.g.

    -X 'n=WH6000,m=FSK_PCM,s=58,r=1000'

Then try that, e.g.

    rtl_433 -f 868M -X 'n=WH6000,m=FSK_PCM,s=58,r=1000'

[stef LP]

Hello Christian and thank you for your answer

I try CubicSDR but nothing is good   for me with this usb key .

I  m trying to use youyr command  :

rtl_433 -f 868M -A  

-X 'n=name,m=FSK_PCM,s=1,l=1,r=1024'

But after I dont know how to decode this  !

Can you help me  ? 

Thanks a lot

Stephane

[Christian Z.]

Use only:

    rtl_433 -f 868M -A

Post the output.

Do not use -X ...s=1... <- this will never work.

Maybe this will work:

   rtl_433 -f 868M -X 'n=name,m=FSK_PCM,s=58,l=58,r=1000'

[stef LP]

Hello back 

I use  this command  to make file 
rtl_433 -f 868M -A  2> WH6000.txt 

I hope it will be good

Best regards 

[Christian Z.]

Yes, the file is good.

There is much noise and the frequency is not optimal. Try the same but with

    -f 868.2M

[stef LP]

Re, 

I use the frequencey 868.2 MHZ 

Stephane

[Christian Z.]

Ok, but sadly not working any better. Too much noise.

Perhaps try adding

    -Y classic

In the output: you don't want any lines of 

...width:    1 us ... (or 2, 3, ...)

all lines must be greater than 50. These look good:

 [ 3] count:   29,  width:  120 us [110;128]    ( 120 S)
 [ 5] count:    8,  width:  243 us [233;252]    ( 243 S)
 [ 6] count:    2,  width:  365 us [365;366]    ( 365 S)
 [ 7] count:    2,  width:  486 us [486;487]    ( 486 S)
That is 1x120, 2x120=240, 3x120=360, 4x120=480. This is the pattern you want. Only that.

[stef LP]

Re Christian 

I dont really understand what you say about lines and number "50"   I believe you   ;)

Thanks ...

[Christian Z.]

Looks much better now. This could work:

   rtl_433 -f 868.2M -Y classic -X 'n=Froggit,m=FSK_PCM,s=120,l=120,r=3000'

[stef LP]

I give you  the result from  the last command :

Have a good night ;)

Stéphane

[Christian Z.]

The data is perfect.

It's the new Bresser 6-in-1 protocol. See this BitBench.

It will "just work" with: https://github.com/merbanan/rtl_433/tree/feat-bresser6in1 from #1225

[stef LP]

Hello Christian, 

I use this version of rtl_433  :

rtl_433 version 20.02-165-g105342a branch master at 202009221012 inputs file rtl_tcp RTL-SDR

I must to take and compile  the last  one  ? and compile all new ? to work fine  ? 

I   view you work on "Bresser  7 in "  too  #1492  https://github.com/merbanan/rtl_433/issues/1492

I  seem  my "Froggit WH6000" it 's  a clone 

Can you tell me how to  to do now ? upgrade rtl_433  software ? I use it on raspberry Pi  with Weewx software 

Thanks a lot 

Stéphane 

[Christian Z.]

git clone https://github.com/merbanan/rtl_433.git

cd rtl_433

git checkout feat-bresser6in1

mkdir build

cd build

cmake ..

make

./src/rtl_433 -f 868.2M -Y classic

[stef LP]

Hello back Christian , 

 thank you very much  ;)

Its work fine  ! 

Now second step  : connect to weewx software 

Thansk a lot 

[stef LP]

Hello Christian, 

My decoding is good for outisde  , but I have sensor inside my house and my question : is it possible to  intercept and decode this sensor  too ? 

I fixed it on channel 1

Thanks a lot

Best regards

[Christian Z.]

Is it the same kind of sensor? Do you have any recordings?

For best recording: remove the antenna from the RTL-SDR and place the sensor at 10cm to the RTL-SDR.

[stef LP]

I use this command  :  
./src/rtl_433 -f 868M -A 2> /home/pi/WH6000/WH6000-inside.txt

in the second file (-2) the result is very good ;)

[stef LP]

Hello back Christian, 

How can I track the two signals in same time  ? channel 0 from station and channel 1 from sensor inside ? 

is it possible ? or not ?

Thanks  for answer.

Stephane

[Christian Z.]

Channel number is not a difference in frequency. Both should work at the same time.

If you need "-Y classic" for one but not "-Y classic" for the other you are out of luck. You need to decide :/
