Hey there @fronzbot, mind taking a look at this issue as its been labeled with an integration (blink) you are listed as a codeowner for? Thanks!

I'm seeing exactly the same issue.

@fronzbot

Hopefully this will be fixed by using the new arm property in the blinkpy package: fronzbot/blinkpy#273

i.e.

self._camera.arm = True on L47 here
self._camera.arm = False on L51 here
