Thank you, this confirms my suspicion — user error. I clearly didn’t set it up correctly, since I am not seeing the red “motion” alert occur at all. Cameras are armed and recording video, but for some reason, either SmartThings or IFTTT aren’t seeing the motion event.
Question for you — do all of my IFTTT triggers look correct to you in the screenshot from my previous post?
Side note—I’m not 100% certain I fully understood the very last step of your instructions (Step C), so in particular I am wondering if I misconfigured those IFTTT applets?
Edit: I just thought of one other potential cause — when authorizing the IFTTT service, I noticed that the cameras appear twice: once under Switches, and again under Motion Detectors. I chose the latter, and I am wondering if choosing the former would potentially fix it.
Edit #2: Huzzah! That was the problem! I had authorized IFTTT to access the Blink Virtual Devices as Motion Detectors, when they should have been authorized as Switches instead. @Gutheinz: It may help others to edit Installation step #4 and specify this. Just a thought… thanks again for sharing your code!
