Well to be honest hubitat most likely wouldn't be here without. st..They started the open groovey devices for zwave and zigbee with their hub.. All the founders here came from there. I recently jumped ship as well due to the debacle.. They are basically getting rid of the classic app which had all the power. worked well and was mature.. They are streamlining with the new app which is slow buggy and limited..(for me with 150 devices it most times woiuldn't even load the pages or did 5 minutes later). They are cataring to the people with 5 devices and a tv etc that don't use custom device handlers and don't care about the power and flexibility of the system etc.
This will make their support much easier but they aer basically punting upower users that have 100-200 devices custom code etc,
In addition, besides the classic app going away the groovey code base will also go away and all device handlers and apps written in it will cease to run. I believe if you host them on your own server or the writer of the apps or devices types does they may continue to work, but this is not confirmed.. They are very closed lip about. it,
Again, much easier to support a system with no custom code etc. and only casual users with few devcies. Unfortunately that is the nature of the beast and the majority of their users,
