My ISY is currently on the highest /last release of v4.x. In order to be able to use UD Mobile I'll need to upgrade to version 5. Since my system isn't very large and currently only exists with Insteon devices I don't expect this to be difficult. However, I'd like to purchase and add the Z-wave module to my ISY as well. Am I better off to install the module before or after the upgrade? Also, is the module listed on the ISY accessories page going to be compatible with Z-Wave+ devices?
