Help To Decode - Mini LCD Display Weather Station XC0400

[Daryl Williams]

Need help decoding this Weather Station: http://www.jaycar.com.au/mini-lcd-display-weather-station/p/XC0400
which I think is a Fine Offset: http://www.foshk.com/Weather_Professional/WH5301.htm

Can you provide python subprocess code to grab rtl_433 decoded data. Just to get the data with python. I can do the rest myself.

here is the output from ./rtl_433 -f 433889906 -a

Anyway the output is hard to understand because several parameters
change at the same time. I suggest you put it in the freezer and get 5
samples where only the temperature changes. And then keep doing it for
all the other fields.

Thank you for your reply Benjamin

I waited to see if you would take some time to look at my post and check the data output I provided.

This morning I woke up early thinking, why can't Benjamin see what I can see. It's right there in the data.

Then I started thinking, how can I explain my findings visually so that not only you can see it, but others will also see it and say oooh aaah.

This is going to take me a while to explain my findings. I will have to write a paper just on this.

http://stackoverflow.com/questions/2804543/read-subprocess-stdout-line-by-line#2813530

 This link is a wonderful suggestion. Although I do know how to use python subprocess. the issue is how do I run ./rtl_433/build/src/rtl_433 in subprocess so I can grab the stdout and stderr output.

When I access rtl_433 in the Ubuntu terminal I use the following command:

I go to the rtl_433 directory

$ cd ./rtl_433/build/src

Then I invoke or start rtl_433 with the following command:

./rtl_433 -f 433889906 -a

How do I run rtl_433 in subprocess when the command "./rtl_433 -f 433889906 -a"  gets an error no such file or directory?
How do I run rtl_433 in subprocess when the command "cd ./rtl_433/build/src", "./rtl_433 -f 433889906 -a" gets an error no such file or directory?

When I am finally able to get rtl_433 to run in subprocess, I can then extract the output data and develop algorithms that will give me all the data I require.

 

Anyway the output is hard to understand because several parameters
change at the same time.

I know several parameters change at the same time. I know what data relates to what senor before I posted my data output on this post. I just allowed you time to suggest what you could see so I could confirm my findings.
 

I suggest you put it in the freezer and get 5
samples where only the temperature changes. And then keep doing it for
all the other fields.

First of all. Not that I feel comfortable in saying this. I'm not exactly young. It took me 2 weeks to work out how I can put the weather station up on my roof.
I finally got it up on my roof and I'm not prepared to climb up on the roof, pull it down and then spend another 2 weeks working out how I can put this quite large weather station in the fridge
with out my wife noticing. All hell will break loose if she sees it in the fridge.

In any case, why should I pull the weather station down and put it in the fridge when I already know what data relates to what measure senor. It's quite obvious to see it in the output data.

All I want to know is how do I invoke rtl_433 in python subprocess so I can start decoding the sensor data programmatically. Instead of doing it manually using copy and paste which is prone to errors.

As noted with the youtube videos I have produced so far. I am very happy to explain to everyone how I use rtl_433. This would be a great service for what you and everyone else who are supporting the development of this wonderful decoding tool would like to achieve.

>MvH
>Benjamin Larsson

So what do I hope to achieve when I finally get to decode the weather station data? My step son does kite surfing on a lake that my wife and I live next to. 2 years ago I said to him, I would like to put a weather station up on my roof so I can get the weather readings and put them on a web page so that he can access them on his mobile phone. Then he can see if the wind is just right for a fantastic day for kite surfing. I won't explain why it took me 2 years to get a weather station up on my roof. That is another story for others to tell.

Hope you can help me with this conundrum Benjamin.

[Daryl Williams]

Okay after more researching. It turns out rtl_433 was installed incorrectly in Ubuntu 16.04.

I uninstalled and reinstalled rtl_433 and now finally I can use python subprocess and can access the output data.

YAY!!!! This is very exciting. Stay tuned to this channel...

Well I tried to see if I could find some patterns in the data. But as I
couldn't see any obvious things I was stuck. And you said you wanted to
figure it out on your own so I didn't spend any more time on it. I also
don't have any signal dumps and matching parameter values to work from
which makes everything quite complex.

Do that, take your time it is always good with some written instructions
on how to figure out things.

:) Ok what also works is to get lots of samples and when only 1
parameter changes then keep track of those matching pairs. I once had an
idea that I would trigger a webcam that was pointed to the receiver and
take a picture of it after every signal. Then afterwards I could just
look at the pictures to see when I got suitable sensor output and the
matching signal output.

Well not obvious to me.

It's All Okay Benjamin

I've done it. After a lot of programming and testing algorithms I got it working.

So I'm running rtl_433 on a USB TV Dongle RTL820T2. Using Ubuntu 16.04. The program is inserting data into a sqlite3 database as I speak.

Eventually I will use a Raspberry Pi to gather the data and send it to a MySQL server on the network. Raspberry Pi will also have a web server that can be accessed on my network so we can see the latest weather measurements.

What helped me decode the data was this link: http://www.susa.net/wordpress/2012/08/raspberry-pi-reading-wh1081-weather-sensors-using-an-rfm01-and-rfm12b/

The problem I had was when I added the weather station console measurements manually to compare it to the data. I found I had made mistakes entering some of the console measurements.

What I enjoyed most of all was working out the cryptic data messages and what measurements they matched up to. It was an Enigma. Then developing the algorithms that would give me the correct measurements.

After a lot of google searching, I came across this python script: rtl_433_wrapper.py

I removed the create sqlite3 table because I have my own programming method of creating and communicating with the database. I then added the algorithms for:

• wind speed
• wind direction
• humidity
• temperature

Yesterday I started writing a tutorial on how I installed rtl_433 so I can run it in the terminal as rtl_433. Once I got this working correctly, I was then able to run Python Subprocess.

It will take some time to write how I determined the various weather measurements in the rtl_433 output data compared to the weather station console. So I will keep you posted.

Can you send some recorded signals ? Run rtl_433 -a -t and send some
samples of the produced files. Preferably both type of signals.

Hi Benjamin. I installed the latest rtl_433 and not my decoding doesn't work for wind speed.  I have done as you asked, run rtl_433 -a -t

I will attach the files generated.

Hi, these samples are good, the signal is clear for a few samples I tested:

gfile002.data -> [00] {87} ff 41 24 62 60 26 2a 02 08 14 30
gfile001.data -> [00] {87} ff 41 24 62 5e 28 2e 02 08 15 1e

Where you able to figure out the meaning of the bitstream ?

Ok, thanks to your files and some tinkering I figured out that the
preamble was only 7 bits. When I added the extra bit and signal
parameters suitable for demodulating the signals, the existing decoder
started decoding the data with something that looks sane.

rtl_433 -l 0 -r ../gfile001.data

Hi Benjamin
Note sure what you meant by the preamble has 7 bits and when you add 1 and extra bit = 8 bits. In my video below, you can see there is 8 bits in the preamble
https://www.youtube.com/watch?v=VarH42bc6o8

Are you saying I can now use: [32] Fine Offset WH1080 Weather Station to decode the signal?

Well lets say that rtl_433 drops one bit for some reason. I added it
back and everything was fine and dandy.

Yes, pull the updates and compare against your receiver. As I don't have
anything to compare against I just assume everything is working fine.

The receiver I'm using is: Blue DVB-T+FM+DAB 820T2 & SDR USB2.0

Hope that helps.

P.S. You are good Benjamin

Well you need to pull the changes from the repository and compile a new
version and then test and see if the changes help. But as you did supply
some test signals that decoded fine I assume that your reception will be
fine again.

[Daryl Williams]

Compiled new version and I get correct temperature, humidity, wind speed and wind direction. But can't work out how you get rain and battery OK.

Will run it over night and test generating graphs.

Thank you Benjamin for you help.

Well send the output and a sample and we'll see if there is anything we
can do about that.

Hey Benjamin

On Saturday 3rd September 2016 here over lake Illawarra, NSW Australia, we had wind speeds between 36 kmh to 43 kmh. I thought I sorted the temperature, humidity, wind  speed and wind direction. But I was getting low wind speed calculations..

This makes me think I'm using the fineoffset_wh1080 (-R 32) incorrectly. Can you explain how I can get the weather data from the generated code?

If some values are not correct you have to look in the code to see how
they are calculated now and try to figure out the correct
representation. The values you posted needs to be inverted and bit
shifted. It is much easier to change the decoder code and output the
correct looking bit stream from there. I did that (git pull) and if you
now run this following command you can see the proper bitstream that the
decoder uses to decode:

src/rtl_433 -l 0 -D -R 32 -r ../gfile001_f.data

Registering protocol [1] "Fine Offset WH1080 Weather Station"
Test mode active. Reading samples from file: ../gfile001_f.data
Input format: uint8

ff a0 92 35 44 02 03 01 e4 00 79

@0.524288s : Fine Offset WH1080 weather station

Msg type: 0
StationID: 0009

Temperature: 16.5 C
Humidity: 68 %
Wind string: N
Wind degrees: 0
Wind avg speed: 2.45
Wind gust: 3.67
Total rainfall: 145.2
Battery: OK

In the output you see a line starting with "ff". If you look into
src/devices/fineoffset_wh1080.c you will see how the bits are decoded.
So if things don't match up with what is on your receiver screen then
try to figure out the changes needed. Then we can think of adding a
profile for you device.
