Totally understand. However, in our case, Guest mode is actually the same whether we are on vacation or not. Sometimes friends come over to hang out with the cats for extended periods of time while we are away (to watch a movie, etc). And, a friend of ours who works from home sometimes comes over to our house for a change of pace during the day and hangs out with the cats (everyone seems to love the cats).
So, in our case, Guest Mode (whether we are on vacation or not) is exactly the same. The reason I’m using a Vacation mode is I’m running the Occupancy Light Simulator. If we are not on vacation, I don’t run it…although I’m now wondering why I made that decision!
