I have 3 Yale locks on a Vera3 but one has always been unreliable as it's installed on a detached garage.
Last weekend we were on GenSet for some 20+ hours and as per usual, Zwave networks takes awhile to become reliable again.
The lock on the detached garage did not fall back into line, even though I have 4 zwave devices just to build a reliable path to that lock.
Been playing with a Wink Hub for a bit now so I bit the bullet and took the lock off the Vera3 and added it to the Wink. Since the Wink Hub only controls some experimental lights I was able to park it in a window facing the detached garage to hopefully get good reliability.
I'm using a python script to connect to the Wink site and load a few Indigo variables every 15 minutes or when some activity happened and 10 minutes after the door is closed I send a close to Wink from Indigo.
Performance is quite acceptable. Only downside is that Internet is required but it's actually a non-issue for me.
If at home, no problem and if away the door should already be locked.
Bottom line... am able to repurpose 4 zwave devices for price of Wink Hub (50 bucks).
Only time will tell if it'll be a success, I.e. reliable.
In the meantime going to try and make a plugin out of the script.
