I recently purchased four Connect Home Pro Wi-Fi Hubs with the intention of adding them to my SmartThings v2 Hub environment. I purchased these with two goals in mind: creating a stronger Wi-Fi mesh network, and repeating z-wave and zigbee throughout my home. However, I can not figure out how to add these to the SmartThings Classic app, which I currently use to manage my environment (~30-40 smart devices). I was really hoping to make these devices slaves to my current SmartThings V2 Hub as I prefer the local operation for certain functionality (lighting etc).
In the documentation I have found, it says you “should” add the Connect Home Pro’s via the Samsung Connect / new Smart Things app. Is this actually a “must”? if so, how do I migrate my SmartThings classic account/automation to the new app?
