I agree with you on the random nature of getting the AWS KVS Slider Live View rather than the TUTK Live View. I have been experiencing random momentary appearances since it’s abandonment.
I also agree that the AWS KVS is a far superior option for immediate notification. It really is a matter of security if anyone is to take them seriously as early warning security cams.
A new beta firmware release was just announced for the Hub a few hours ago, so you may wish to wait a few days and watch the replies. I may update tomorrow or Friday.
