So they admit that data stopped around the 23rd. I don’t use the motion on the Arlo cameras for any SmartThings triggers. However, I just tested it, and no motion is working in SmartThings from any Arlo devices for me either.
At least I can still control the On/Off state of the Arlo cameras from SmartThings at least.
The thing is, the SmartThings/Arlo integration has been slowly getting worst over time since the 6 hour periodic check has become more like every 24 hours now. To me, Arlo has been struggling since it’s breakup with Netgear. But then it could just be something like the Log4j vulnerability causing them some frustration. Hope they resolve it now and not wait for SmartThings Edge migration.
