Frequently goes offline for like an hour or so despite having a strong wifi signal. I've never received an app or email notification for the schedule I configured to run every night so I don't know if it's even running. Also, it should use the event time for the notifications, not the current time. I can't tell if someone else has opened my door now or it's just the notification for when I opened the door previously, arriving on my phone 90 minutes late because the unit has been offline.
