Comment below if you've ever run into anything like this with your home automation system. This is the first time I've noticed this sort of issue. I've had many internet outages (cough, Comcast, cough) in the past but this is the first one I've noticed that spanned either sunrise or sunset times. The fail safe logic I have now is working well and seems to handle this short term internet outage with my testing. Although I'm looking into a more robust fix that should handle outages of longer duration. The neat thing is you can write up that code, add it to the other condition expressions and the PLEG environment will execute that code and you can see the state changes and time stamps. It takes some time to work through all the scenarios that might happen and then implement fixes for all those in one line of code.
