The PGE outage last week exhausted my panel battery, and once power was restored, no Z-Wave devices were operational. The panel says none are there, except PC Controller. I have attempted to re-add them back in but the panel discovers no devices when I attempt to pair. So I am not sure if this is a 2GC panel issue or Z-Wave device issue. If device it means all of them have failed? Security portion of panel works fine.
I know there is a panel reset via disconnecting power and hold both front buttons while power up. I suspect this wipes out ALL programming, including security however.
Sooo… Ditch Z-Wave and go with WiFi, try the panel reset and see if Z-Wave returns, or?
I do like the stand alone notion of the Security and minimal light control from the same panel, however I am loathe to repeat what I think is in store for me. The majority of my Home Automation is on WiFi, and Alexa control so maybe this is the way to go, but not sure what I may lose from Alarm.Com.

Happy to help! Unfortunately there is a known issue which can affect the GC2 on total power failure where this exact scenario occurs. It is rare, but it is definitely a frustrating issue.
Fortunately you should be able to add the devices back just fine. Z-wave devices internally save the parent network info. Since it is a two way communication protocol the panel and the devices pair to each other, not just the panel listening for the devices.
This means that if the panel Z-wave controller is reset (or this bug caused by full outage) then each individual device still retains the old parent network link and cannot be readded until a Remove Device operation is used on each one.
For each device, go into the Z-wave menu and tap Remove Devices. Press the pair button on the device, the panel should say that a device has been cleared. You can then add it using Add Devices.
This must be done for all Z-wave devices.
If you are looking for alternate options, lighting automation devices could be replaced by Lutron RadioRa2 or Caseta. These would still be compatible through Alarm.com.
