The order of the time bars in the Visual Scheduler appears to be random. Is there an ordering?
Yes. The time bars are ordered by housecode and unitcode. This was done for a reason. Normally as you lay out devices in your home, devices that are physically near each other, in the same room for example, typically are given the same housecode and sequential unitcodes. By ordering the time bars in the same way you can compare and contrast how devices near each other are scheduled.
