That is extremely upsetting but not in the least bit unexpected.
I sincerely hope that you remain in the forums and if, IF, smartthings gets their act together that you will begin support again.
I honestly believe they will, but I understand that you have a much deeper vesting in their platform than I do, and I do not blame you for this move.
Unfortunately, I also believe this is only the beginning.
As others have said, please let me know if and when you find another platform, as I would definitely join you.
