There’s not really an official integration with Blink and ST directly, even in the US. @RBoy makes a Blink device handler and smartapp that does integrate Blink really well. Well worth the cost to access his apps, you get a bunch more too if you purchase a license on his site.
See the Blink thread, it’s super long but the first post is up to date about what works with ST. It makes the Blink cameras much better than they’d otherwise be.
Cloud recording is unavoidable with Blink and most of the other wire-free cameras. It’s free now, they plan to offer more tiered monthly plans for their upcoming security system that will cost extra. But they don’t seem to have any plan to remove the free cloud recording entirely.
