What is the difference between de vera lite and vera2
Welcome!
There’s probably several previous topics discussing this. Perhaps have a look at this wiki page also.
Vera Lite is newer and more powerful than Vera 2, probably resulting in a better overall experience; certainly as the number of installed devices and plug-ins goes up. No WiFi on Vera Lite.
Perhaps think of Vera 3 as the more powerful successor to Vera 2, and Vera Lite a stripped down Vera 3 at a lower price point.
