Withings

I too have a Withings scale which I’d be interested in integrating the data from with MM.

It’s next on my list to take a look at, but I suspect progress is likely to be slow as my skills are very basic :)

I’ve been having a very quick play with this python script on my Pi, which demonstrates the API which could form the basis of a simple weight-data retrival module.

I’m struggling with a few issues at the moment though - I’ve git clone’d and npm install’d, created a test.py file as indicated by the readme and in it I’ve put in it my Withings API key and secret values.

I had to sudo pip install requests_oauthlib as that was a requirement which wasn’t installed.

I’m SO nearly there I think! when my test.py file runs, it generates a Withings URL to authorise the app, I authorise on the website and am given an oauth response verification code, but when I paste it back into the script response, I get an error which i think is at the point the script tries to parse them through auth.get_credentials (after this point, the script gets my last measured weight):

 File "test.py", line 8, in <module>
 creds = auth.get_credentials(oauth_verifier)
 File "/home/pi/MagicMirror/modules/python-withings/withings/__init__.py", line 107, in get_credentials
tokens = oauth.fetch_access_token('%s/access_token' % self.URL)
File "/usr/local/lib/python2.7/dist-packages/requests_oauthlib/oauth1_session.py", line 304, in fetch_access_token
token = self._fetch_token(url, **request_kwargs)
File "/usr/local/lib/python2.7/dist-packages/requests_oauthlib/oauth1_session.py", line 361, in _fetch_token
raise ValueError(error)
ValueError: Unable to decode token from token response. This is commonly caused by an unsuccessful request where a non urlencoded error message is returned. The decoding error was No JSON object could be decoded.

Oh well. It’s progress I suppose.

I got the withings scale, interested about the module you’re building :)

So the Python module I was trying to re-use didn’t work. I suspect Withings have changed their API or something else has changed. Following the steps on their website though, did work and I was able to send a command to retrieve my data.

Now it’s a case of trying to code it up into a module!

Hi,

Just upload first version of my module. This is more a proof of concept than a complete functional module, but it works fairly well on my mirror.

MM_Withings

Will update and improve it (especially design, if someone could provide me nice icons) and create new post in module section forum.
Module is based on Netatmo module from Christopher Fenner.

@matt25 What do you put in for the application website when creating the application on the withings site? Seems to be needed later when granting access - and I get a 404 error if I just put some random site mane in there.

matt25

@frog I personally simply wrote 127.0.0.1 and no problem. Let me know if it is ok so that I can complete the user guide.

frog

@matt25
The problem I had was that I was ssh’ing into my mirror - so I tried running the Withings authorisation process on the mirror using Chrome, but I’m now getting a message that 127.0.0.1 can’t be reached.

matt25

@frog Ok sorry. When creating a withings app it is necessary to write something in the application website (127.0.0.1). In the Withings authentification process, do not fill the the ‘callback url’ field. Hope it helps.

frog

Ah, OK,

Now a different error.

When I get to Step 3, do I stop there or continue on (I’m getting a Bad Request on step 4)

Also it says in step 2 I should get a URL once I access the user - but I get Access Granted - and another token - no URL.

To be clear about the parameters for the config.js:

oath_consumer key is the key given in the partner app page. under My Keys and called APIKey

oauth_signature is listed right at the bottom in the black box in step 3.

clientID - no idea what that is

oauth_token is taken from the black box in step 3 and is highlighted. There are two copies of it.

Oh, One last request about functionality. It would be great if you could specify in Config.js which readings are actually shown. I only use the scales and so the other stuff is superfluous. I suspect the majority of people would not necessarily have the full set (steps and sleep).

matt25

@frog

Seems that you are not using correct parameters in the Withings authentification process:

Step1 : Use API keys and API secret generated during your Withings apps creation.
You get a result URL with oauth_token and oauth_token_secret.
Step2: Use oath_token and oauth_token_secret generated at step1. This will generate a result URL. Click on it and look at the adress bar, you will get in the URL your userid (6 digits), ‘&userid=xxxxxxx’
Step3: use the userid got from step2. you will get an URL result with oauth_signature and oauth_token.

Hope it helps.

Selecting the data you want to display is the next step, that is why currently this is just a basic module and I did not yet published a official release.

@matt25 Hi,

Thanks, with your pointers, I got through to step 4 and the resultant URL does retrieve data so I know the credentials are working- but putting that into the config.js (all info it looks like you ask for is contained in that request URL), I still get zeros.

I suspect I’m close, but not sure what could be wrong.

@frog I’m getting the same results as you. I suspect the MM_Withings.js script needs to be tweaked a bit. I manually tested all the variables used in the config.js file, confirming that the API is setup correctly and returning data. My guess is that the output string of the MM_Withings.js script is different than what I’m testing.

@ih800a @frog

Hi, sorry, was out last few weeks. Just tried the module on another raspberry card with from scratch installation and I cannot reproduce the issue you describe. When you launch the mirror, do you have any issue in the logs? (use “npm start dev” command). Thanks

ih800a

@matt25

Per the console, I do receive weight (poids=90.67;) and date (date=1481195497) information, but then see the following:

status=0
error TypeError: Cannot read property ‘date’ of undefined
error TypeError: Cannot read property ‘body’ of undefined
data=undefined
data is null

matt25

@ih800a
ok thanks.
Do you only have a Withings scale, correct? or do you also have a watch or others?

My guess is that as my module is just currently a proof of concept, I try to display all the related information (weight, sleep, activity ) but if you do not have the withings device related it crashes.

Also, could you tell me when:
“error TypeError: Cannot read property ‘date’ of undefined”
which line in the MM_Withings.js script is related. It should be written in the debug console. Thanks

ih800a

@matt25

I have a few Withings devices (pulse, scale, BP monitor, etc), so your theory makes good sense. Kudos, by the way on this proof of concept - I like it and this will be one of my first Pi / Magic Mirror / module customizations, so I appreciate any insight you have.

The errors appear at MM_Withings.js:208, which I believe is the line that writes the error to the log.

aluini

I corrected some things on the module :

correction of the @ih800a bug (I had the same)
add external CSS
add the loader
add translation

I’ll review the design of the module

Snille

Hi @aluini, is your module still working correctly? I’m only getting the weight. :)
I have an Body Cardio Scale, do I have to define this somewhere?

Thanks!

Nice. I want to test it.
My data from my withings steel also showable?
