I have a Chamberlain garage door opener. The MyQ and the built in wifi (i have built in) will not really help the OP. He is looking for the instance when he is incapacitated. Part of Chamberlain's terms of service with home automation wont let the door open/close through automation. You have to initiate it yourself through your device (open the home automation app, or talk to siri to open/close the door).
I have an android based GPS system on my motorcycle, the Chamberlain app wont even save the password, because it believes the unit is rooted.
