I use SmartThings to turn the Arlo cameras On/Off and just leave Arlo in Armed mode all the time. Because even though Arlo is in Armed mode, it won’t do anything if the cameras are Off.
So, when you setup the Arlo (Connect) service in SmartThings, do you actually see all eight cameras from both Arlo accounts, or do you just see the cameras from the account you used for the connection?
