Query about 2FA in latest blinkpy 24.0

[HughAndersonNUS]

Hi,
I have some scripts I use to autonomously query blink camera systems. They use a creds.json file generated using the sample code, and which now have a "2fa_code": "XXXXXX" at the end, and an "expires_in": 14400, field. This new creds.json file seems to work fine for a while, and then my scripts start asking again for a (new) 2fa code. Since this code is just running in a cron job, the scripts stop working. I feel like I am misunderstanding something. My scripts to retrieve code are like this:

async def start():
    blink = Blink()
    auth = Auth(await json_load("creds.json"))
    blink.auth = auth
    try:
        await blink.start()
    except BlinkTwoFARequiredError:
        await blink.prompt_2fa()
    camera = blink.cameras['DB-Driveway']
    await camera.snap_picture()       # Take a new picture with the camera
    await blink.refresh()             # Get new information from server
    await camera.image_to_file('TEMP/DB-Driveway.jpg')
    return blink

blink = asyncio.run(start())

Can someone suggest what I am doing incorrectly? Is there some way to allow for a script to continue working for a long time the way it used to?
Cheers Hugh

Hi - I think I have got this working properly now. I had installed the latest blinkpy code using pip install blinkpy, which appears to install blinkpy 0.24.b0:

hugh@homeOdroid:~/SCRIPTS/BLINK$ pip list -v
Package               Version          Location                                       Installer
--------------------- ---------------- ---------------------------------------------- ---------
...
blinkpy               0.24.0b0         /home/hugh/.local/lib/python3.10/site-packages pip
...

So instead I installed the development version:

hugh@homeOdroid:~/SCRIPTS/BLINK$ pip install blinkpy==0.24.0b1
...
hugh@homeOdroid:~/SCRIPTS/BLINK$ pip list -v
Package               Version          Location                                       Installer
--------------------- ---------------- ---------------------------------------------- ---------
...
blinkpy               0.24.0b1         /home/hugh/.local/lib/python3.10/site-packages pip
...

After this, the code worked as expected, although I had to change the import line to:

...
from blinkpy.auth import Auth, BlinkTwoFARequiredError
...

Now, my code has worked for 16 hours without prompting for 2FA.
Thanks - cheers Hugh

Hi @HughAndersonNUS glad that worked. Hadn't had a chance to respond but that's exactly what I was going to suggest. However 0.24.1 should be the most recent release if you want to update to that. Technically there's no code difference between that and the b1 version you have, but just wanted to mention that
