i had a power cut today and i was not home, however when the power returned the door opened, which i was not expecting to happen, how can i stop this happening as its a security flaw.

Me too

I don't know how you guys have your garage door hooked up. But I used a the Inching / Self-locking Smart Switch and don't have any issues when the power goes out. Basically you hook it up like you would an old school garage door switch. The Inching function returns the device to the off state, which mimics a physical button push. 

sounds the same as mine, i have it connected across the terminals where a remote switch would connect to on the garage closer, my device has the inching set, but when the power goes off then on the door opens

I have the SV in inching mode, connected across the normally closed and set to be in "off" state on power up with firmware 3.0.1 and one with 2.7.1. Both work perfectly, no issues on power on. On the Gate is is wired on the manually open gate with push button switch and on the Garage door, the same thing.

Have you tried setting the default position at startup? I'm not sure how quickly it will enable on power up, it might still be slower than the garage electronics waking up...
