I wanted a device to help me monitor the door closure state of my freezer in the garage. I found a temp\humidity sensor that worked great, except it goes through a new battery about every week. What I thought I’d try as an alternate approach was to use a door contact sensor to send an alert if the door was open for for than 2 minutes. The “Stays this status for how long?” feature helps me do that. However, it would be really helpful if this feature could be extended to repeat the alert\text every few minutes until the contact is closed.
