As a recent refugee from SmartThings frustration-land I have gotten more and better automation set up in a couple hours with Hubitat than I ever did with ST. Major props to the Hubitat creators!
The only thing missing from the default device support from my point of view is Lifx. These lights are pretty popular and I have a bunch, are they planned to be supported devices in the future?
For now I've found the Lifx group of groups community driver but it is less than idea in that it only controls lifx groups instead of individual lights and uses the lifx cloud connection. If it isn't planned to be supported in the near future perhaps I will take a stab at a local lifx driver if I can find the time =)
