When I run python3 get_credentials.py the resulting token is in some strange format that Home Assistant doesn't like.

<80>^D<95><80>^D^@^@^@^@^@^@<8c>^Ygoogle.oauth2.credentials<94><8c>^KCredentials<94><93><94>)<81><94>}<94>(<8c>^Etoken<94><8c>TOKEN REMOVED<94><8c>^Fexpiry<94><8c>^Hdatetime<94><8c>^Hdatetime<94><93><94>C
^Gæ^B^D^V^P^\^N9<87><94><85><94>R<94><8c>^Q_quota_project_id<94>N<8c>^G_scopes<94>]<94>
...

I'm assuming this should be a JSON string. @IvanVojtko Can you point me in the right direction to generating a proper token?

When i access the URL generated by get_credentials.py and check all permissions and click Continue i get redirected to a URL like http://localhost:8080/?state=rYmM5PTvl7MbN... and the script will not generate a .google_fit.token. When i check the generated URL, there is a "redirect_uri" parameter which specifies the localhost:8080.

Did i miss something in the configuration?

// Edit: I found, that in the credentials.json the "redirect_url" to localhost is specified. I changed it to my external HA domain, but then Google gives the error "Redirect URI mismatch".

Hallo, thank's for Your job, I've follow all the procedure, but finally I have no idea that how i can finalize the HA data access, please, can You explain step by step how i can run script and optain authorisations?! Thank's in advance, Gdi

I was able to get your integration working today and it is very cool! Thank you for creating this. I am wondering if it is possible to pull Fit data from to different Google accounts? I'd really love to be able to pull stats from my Fit as well as my girlfriends. Perhaps multiple .google_fit.token? Thanks in advance!

After couple of days working the integration stopped providing data, log says:

google.auth.exceptions.RefreshError: ('invalid_grant: Token has been expired or revoked.', {'error': 'invalid_grant', 'error_description': 'Token has been expired or revoked.'})

while trying to re-authenticate with google, google says

You can't sign in to this app because it doesn't comply with Google's OAuth 2.0 policy for keeping apps secure.

I am only one experiencing this?

Hi! First, thank you for creating this integration. I've only been using it for a bit over a day now, but I've been really enjoying it so far.

The only maybe-issue I'm running into so far is with the Google Fit heart rate sensor. Specifically, for me, it seems to update very irregularly - often only once every several hours - and the resulting data and history in Home Assistant have little in common with the data that's visible in Google Fit directly.

Here's an example, with my February 8th heart rate data as shown in the Fit app overlaid on a graph of the same time period in Home Assistant.

I'm new to all of this, but especially the Google API stuff (I just fumbled through the API instructions, I think correctly), so I don't know if this 'problem' is something I did wrong, or something up with the integration, or if this data is just as good as Google is willing to offer.

Any help or insight on how to get better heartrate data (or just confirmation that this is as good as it gets, disappointing as that would be) is greatly appreciated.
