Indeed you have posted live logging logs which are one way to see whats going on in your environment. The post tfleming is commenting on covers WAY more than just live logging. I’ll be honest @Judgless i have no desire to go deep diving into someone else environment to determine whats wrong, but providing tools or distilling info to help people figure out weather or not it’s smartthings or them is my speed. If all you are looking at is live logging than i would recommend taking a deeper read of the FAQ below and overview the logs of every component that is required to turn a light on i.e. hub, device (lightbulb) and smartapp:
In the end you may simply see its scheduling issue and completely on smartthings but adjust the time +/- 2 mins may make it more stable. It’s also equally possible with everything you have posted to be a distance/interference issue, a crappy custom smartapp, a crappy custom devicetype or a crappy quasi supported device.
So all the advice i have is use all the logs and test till you figure it out.
