I posted this earlie ron the "Futures" thread, but...
It sounds like an external power connector is MANDATORY based on the current battery life issues. Battery back-up is nice; but constant operatbility is required for this product to be useful.
I have plenty of micro-USB tablet and phone charges stuffed in a drawer. Please add a micro-USB power connector to the both sides of the Lockitron (to accomodate hinges on either side of the door). The hinge that Pete found is great, but I don't need anything so fancy: just a straight run from the Lockitron connector to the edge of my door. I'll figure it out from there.
All these battery preserving "polling", "wake-up/sleep" algorithms are too complex. Just make it simple and make it work. This is not a mobile device, in fact it is being installed in a power rich environment. It's time to ADD the cord. Within the limits of my internet connection to the lock, I want "instantaneous" responses from the lock (5 seconds maximum) I am (generally 700 miles from the lock in question)
I am very much looking forward to getting my Lockitron!
In the meantime I have purchased a Chamberlain MYQ-G0201 MyQ-Garage Control for $129 at Home Depot (also at Amazon); that gives me both remote monitoring and remote control to my mothers home to confirm when care-givers come and go. It's not as elegant as using the front door but it gets the job done.
