Way late, but this should help others jumping from ATT like myself. Many sites say to replace the z wave module in the lock itself. This unnecessary. The ATT one will work.
In the ring app go to devices>alarm base station>Base station>Settings cog at top right> Advance options>Z wave>Remove z wave device.
On the lock Enter master code then # 7 # 3
And this will clear the old settings.
Now you’ll add a z wave device.
Set up device>Security>Works with Ring>add button
On the lock Enter master code then # 7 # 1
Hopefully then you should follow setup step on the ring app.
To set up the jasco (same as GE plugs) ATT provides I got it to work with these steps.
Plug something into the z wave side of the plug and plug it into a wall socket and hold the middle button for over 1 minute. Then in the ring app:
Setup device>security>works with ring>add button
When it is listening, press the jasco main button once and it should sync.
*I actually was able to reset the jasco plugs much easier, without the 1 minute hold. Just follow the steps to remove the z wave device and unlearn will wipe it (same as door) the just press the button once. And to relearn press the button once as well. *
I believe the ATT door and window sensors don’t work with the z wave frequency but I’m still trying them. They also won’t alarm the system but it would still be useful to have them.
