Use Blink Mini camera without Amazon subscription

Blink Mini is a cheap camera. Auto detection is a bit awkward to me as it always detected change out of the region I set for motion detecting. And after one year, recording video stop working without subscription.

Luckily, there are Open Source solution, using Python, likely are all based off the documentation at: https://github.com/MattTW/BlinkMonitorProtocol: 

1) https://pypi.org/project/blink-cameras/ I didn't try it as likely the development was paused since May 2019

2) https://pypi.org/project/blinkpy, github: https://github.com/fronzbot/blinkpy.  This library was built with the intention of allowing easy communication with Blink camera systems, specifically to support the Blink component in homeassistant.

Following is note for using blinkpy.

The blinkpy github site has a brief introduction for how to use it. Information at the pypi.org page likely is out-of date, as module 'blinkpy' has no attribute 'Blink'.

When I try the example code from the Readme, I got this: 

Unclosed client session

    self._write_fut = self._loop._proactor.send(self._sock, data)
AttributeError: 'NoneType' object has no attribute 'send'

Sounds like the connection isn't successfully established? Actually it isn't. I added more code to read the camera name and attribute, and all these information can be read back correctly before above error showing up. Likely, above error raised at the closing or exiting. As a comment for aiohttp issues 5941, loop._proactor is None means loop.close() was called before session.close() call.
This is incorrect; and not aiohttp problem.
