Sometimes a neighbor has the same code in their opener and when they open their garage door yours will open too. You can change the code in your opener.

Oh I had one of those darn garage doors in a suburb of identically built houses, the builders use the same opener on all the garages, and my neighbor would open my door several times a day..... arghhhh.

A neighbors remote is probably triggering it.
I agree with above comments. Somebody in your neighborhood has the same code as you. Probably very nearby. Change your code. Best wishes.
My opener lets you access the setting in the clicker and main control. You just have to reset the numbers by moving tiny switches to match on both.
