I have enjoyed mydooropener for 2 years now and I really like it.
the risk I was always concern about is that the door stay open all night and it is happening to me 2-3 times per years.
mitigation strategy are that we use the push notification that are built in but I would need more protection.
The ideal would be that you integrate your product with IFTTT (if possible). See the garage door opener called Garageio at https://garageio.com/
I'm thinking about buying it because I would built an IFTTT recipe see; https://ifttt.com/garageio Example: 1) if I arrive home open the door OR 2) if it's 10 pm and door is open, close the door and send email OR 3) it door open, open a wemo switch OR 4) if NEST know you are away, close door if open, ... possibilities are endless.
1 item that would help me wait would be if I can get a push notification at 11pm (specific time) ( I tried getting current time from NTP server and got it to work on it's own but I was unable to integrate with mydooropener sketch ... lacking skill to do it!) or an automatic close like reported in other post.
thanks and congratulation for this good product !
