instal and configuration

[GuidoSee]

Hi all and thanks for this, I don't really undersatnd py code, but i've been running downloads from Garmin and processing a Json file via matplotlib so this is a life saver for aging parents needing health data. I'm having an issue at the credentials part. I've installed the Py and upgraded, I can see the local directory on my windows machine containing my .venv files and i've download examples.py.

If I run
python3 ./example.py
it say no valid tokens and please login, I login with a valid uname/pword (redone 3 times) erorrs out with "certifcate verify failed: unable to get local isssuer certificate (_ssl.c:1010)')))

when I run
python3 ./demo.py
i get a 'no module named 'readchar'' error

when I run
pip install ./demo,py
it errors with no a valid editable.

my first spot of confusion is the line "garmin = Garmin(email, password)
garmin.login("/.garminconnect") # later runs: Garmin().login("/.garminconnect")"

where do I run this from ? cmd or py prompt

Thanks

To your last question first: garmin = Garmin(email, password) and the login line are Python code, not cmd commands. You don't need to type them anywhere because example.py already does exactly that for you. It tries saved tokens first, and if there are none it asks for your email and password and saves new tokens to ~/.garminconnect (example.py#L98-L129). So the "No valid tokens found" message on the first run is normal and just means it hasn't logged in before (L113).

The readchar error is because demo.py imports readchar (demo.py#L33) and that isn't part of the base install. It lives in the example extra (pyproject.toml#L111-L113). pip install ./demo.py can't work because pip installs packages, not scripts.

One Windows gotcha too. A venv on Windows only has python.exe in its Scripts folder, there is no python3.exe. So python3 ./demo.py may be running a different Python outside your venv, which would also explain the missing module. From cmd, in the folder where your example.py and demo.py are, this should get you going:

python -m venv .venv
.venv\Scripts\activate
pip install garminconnect readchar
python example.py
python demo.py

If you cloned the whole repo instead, pip install -e ".[example]" from the README does the same thing.

The certificate error is the real blocker and it isn't a code or password problem. "unable to get local issuer certificate" means Python couldn't trace Garmin's certificate back to a root it trusts. Garmin's login site verifies fine against the standard certificate bundle that gets installed with requests, so when it fails like this it usually means something on your PC or network is putting its own certificate in front of HTTPS traffic. Antivirus "HTTPS scanning" or "web shield" features and work or corporate networks are the usual suspects. Trying from a different network, or switching off the HTTPS scanning option in your antivirus, is the quickest way to confirm.

If you'd rather keep the antivirus setting, you can make Python trust the Windows certificate store (which already trusts your antivirus or company certificate) with:

pip install pip-system-certs

That patches Python's SSL to use the Windows store, which covers the plain requests login paths the library falls back to (client.py#L515-L524). Install it inside the activated venv and run python example.py again.

Thank you, I've done some digging on the script issues and I've got a bit further with that, the Garmin site gettings an SSL Error I suspect is because I@m going through a SaaS proxy which I recon is not honouring the Cert consistancy. So I'll try another open machine later today, see if I get a different reply. many thanks for clearing a whole load up. Much XD

Just to confirm that SSL error i thnk was down to a Proxy FW. I connected and got login succesful, token saved and today read out from Garmin.
I now need to work out how to run the API's to send outputs to the doctor. Thaks v mcuh.
