I don’t have these cameras, but a the company released HomeKit integrations for both the Arlo 2 and Arlo 3 last week. The Arlo 2 has a SmartThings integration, the Arlo 3 does not but does work with IFTTT.
A friend of mine has confirmed that even after upgrading the firmware so that his Arlo 3 can work with HomeKit, it still works with Ifttt as well.
Can anyone confirm if the Arlo 2 upgraded to work with HomeKit continues to work with smartthings?
Thanks!
