I use a different app called WINK as a backup. IF you go that way, use caution as WINK is powerful.
I set WINK to send me a email notice if MyQ Chamberlain garage door is open for four minutes or more. The four minutes was a value I chose. I get alarms on my cell phone when ANY email comes in.
Perhaps you may want to set your MyQ settings. My cell phone requires a PIN code in order to function MyQ, but I had to set that option in the app. Otherwise, it is a simple login with the possibility of the cell phone keeping the log in saved. An accidental bump could then open the garage door. Same for my laptop.
I am sorry to hear that you are having issues with the door opening (closing) on its own. The symptom that you have described is called "Phantom Operation". The most common cause is caused by a neighbor's remote being inadvertently programmed to your opener, which could have happened when you programmed your hub to your opener. What you will need to do is clear the memory of your opener and then reprogram any remotes, keyless entries and MyQ Garage back to the opener. I have included troubleshooting instructions below.
Answer Title: Why does my garage door opener activate on its own?

Thank you for sending the instructions. My concern is that I did not receive any notifications that the garage was opened. Additionally, if my neighbor's remote opened the door then why didn't it also close when the neighbor closed their garage door? The 2 occasions the door was opened it was not fully opened but approximately 80% open the 1st time and 10% open the 2nd time.
I took a screenshot of the myQ status which showed "STOPPED FOR 10 HOURS" and the picture was of the door 50% open (the door was actually about only 10% open). Again I didn't receive a notification but the myQ status was "stopped". See attached picture. So being I took this picture at 8:16 AM and the door was stopped for 10 hours means the garage was open since the night before.
And I do have 24 hrs surveillance camera and do not see any neighborhood activity during that period.
I hope not a security issue or bug at Chamberlain end will try to isolate issue by disconnecting to gateway!
