I have shifted to build my modes/scenes logic into room lighting and so far have been successful but discovered I needed to break up the work into 3 categories:
- Vacant (day, evening, overnight)
- Home (day, evening, night)
- Guests (day, evening)
However, I get an unexpected error when attempting to load the child instance app for Guests.
The logs reveal issue with "9" null property on line 3058 but not sure how to tell what line that is 
Any ideas?
Attached screenshots and have txt export of app but can't upload here.
