My current primary use for the Gcal app is putting in mine and my wife’s work schedule. I used to use the all day option but Gcal doesn’t like that method alot.
So I have our work day start before we actually get up. Me 1st 5am and my wife at 6am.
I then use core to compare the contacts associated with those Gcal triggers. If she’s off then when I leave for work and lock the door it turns off the lights. Then just the opposite if I’m off and she’s working. If we both work everything shuts down using the Good-bye routine when we’re both gone.
I plan on using those contacts to trigger the bathroom towel warmer too. Just haven’t gotten to it yet.
Just be aware the Gcal will trigger at midnight every night even if it isn’t supposed to be on. It’s a glitch in the app. Other than that it has worked very reliable for me.
