Just another update.
Had a couple of instability problems with my veralite. From time to time the engine that runs the automation (Lua) crashed. Eventually the unit would reboot itself and all was well. I decided to start monitoring the memory usage and it seemed that eventually the memory would dwindle down and cause this problem. It was able to recover memory sometimes, but others times it wouldn't. Some kind of memory leak would be my guess. Could be related to the number of devices I now have and all the z-wave traffic my energy monitors generate. I made 3 changes:
1. I now have a scheduled 3AM reboot.
2. I reduced how often my energy monitoring devices send data (KWH, Watts, etc.) to the vera.
3. I removed all plugins that I don't use.
These changes seemed to have led back to good stability. Memory usage still creeps up overtime, but the clock is effectively reset with the reboots. I still log and monitor the memory and cpu utilization in case I need to diagnose other problems.
Right now it seems the vera3 is only a few dollars more than the veralite. I think it has twice the memory of the veralite, so it might be worth it if you are going to add a lot of devices... It can also serve as a router, and probably an access point.
I've turned an old cellphone and tablet into automation controllers that are placed around the house to control things (like from the bedroom where my wife doesn't normally take her cellphone my wife can run a scene to make sure the doors are locked, garage doors are closed and alarm armed. Or make sure lights left on in the basement are turned off. Or disarm the alarm, or...)
At some point later this year I'm going to look into iRule for my Home theater room, and integrate it with that. Don't have the time now, and I want to finish off my z-wave installation. I think I'm going to add about 3-6 more microcontrollers for switches, maybe another motion detector, maybe a temp/humidity sensor, maybe another flood detector or 3. Come christmas time I'll probably use appliance switches for christmas lights.
I'm all in at this point. I guess I have been
