I'm a home user with Level 1 certification and limited experience. Question: If I upgrade to Essentials 12.2 will I have to purchase a Connect Bridge for the system to work? I currently have 12.0 firmware. I ask because under New Features, Item 4 is: Remove Support for LHC+Mobile App: Details are provided to the user of the app for upgrading to the Lutron Connect app which provides an updated user experience without a subscription. A quick look online has the cost of the bridge at somewhere around $225. One other question. In my reading of this forum it sounds likes one bridge model had issues. Is there a model number that I should get, if I decide to do that? Thanks.
