After about a month since my purchase of the Hubitat I finally have all of my devices ported over. All automations are humming along, so today I turned off the SmartThing hub.
My port strategy was to move blocks of devices over making sure each one was working. Then using Hubconnect I mirrored the ported devices back to SmartThings so I could keep all automation running with minimal interruptions. After I was sure the hardware part was all working well I ported all the automation over and after a few days of debugging everything is in place.
In a way its sad saying goodbye to SmartThings but it had to happen at some point. During the month long conversion there were numerous times where the SmartThings platform would be acting up. Almost like it was sending a message, so you think your going to leave us, huh? As I was deleting devices the app was timing out, or crashing outright. Lots of strange behavior but that is all in the past. After sitting on the fence for a year I am glad I finally made the move.
