I believe my white series switches (Dimmers and fan dimmers) Were all just updated in smarthings.
I am having issues with my fan switches now. They have lost all of the settings that were specific to them being fan switches.
They now look like they are regular dimmer switches. I set them to dimmer+single to try to see if they work, but they do not operate correctly for fans. They do not have the 3 speed fan setting or any of the fan setting in smart things anymore.
