I don’t think that this will work. Blink Motion Detection only works when the System is ‘activated’ and you also need to call the Service blink.blink_update to get a state update. (default scan_interval is 5 min) But it’s not good to do that frequently > https://www.home-assistant.io/integrations/blink/
Better solution would be an additional Motion Sensor.
Wow that REALLY limits what can be done with this system. Between that, the lack of Google compatibility, and the TERRIBLE Alexa functionality, I’m really starting to regret getting this system at all.
Hard wiring was not an option though, so, battery operated and on sale at the time? I jumped all over it :-/
Does anyone know of any weatherproof/waterproof outdoor motion sensors that could be used for this purpose? I’m searching online and only finding motion sensing floodlights and such :-/
Edit: I’m thinking for my use case (knowing who is at the door when they ring the dumb doorbell), my best bet might just be to trigger an automation via Casa by asking “Hey Google, who is at the front door?”, having it run this - take a picture, refresh Blink, analyze the picture - automation, and then hopefully five seconds later have it say, based on a logo it sees in the image on the truck - “It’s UPS” or whatever … of course, in five seconds I should already be half way to the door, but whatever, it’s about making it more than anything I guess.
