I chose Ring over Nest because it’s not a completely closed system and integrations are possible, IFTTT, Simplecommands, …
I’m a diy enthousiast however and I like to take control over my home automation as much as possible.
To my knowledge there are no (properly) working open source integrations with ring available however.
Is there a chance that ring will ever open their api to the diy community and allow integrations with openhab, home assistant, node red, etc…
