Our notifications are also putting the name of the garage as "undefined" now. We got a notification that the garage was open for x minutes but this morning when my husband closed the garage, it bounced back open and the app kept reporting it as closed, so we never got any notifications about being "stopped" or open.
In just the two days we've been using garadget, I've also noticed that the app needs to be restarted every time you make changes. When we installed garadget, it did not work until we restarted the app. When I set alerts on my phone, my husband did not get any alerts or see any changes on his phone until he restarted/reopened the app. I'm wondering if it doesn't know that the garage stopped closing unless you restart and reopen the app?? If so, that seems like a dangerous security flaw.
