Ecobee Set Present

Has anyone been successful in changing the Ecobee climate mode (or preset mode as referred to in the component) though an automation or script? In the GUI, Action Type > Device does not seem to work as the menu items under Action and preset_mode jump around as I try to make selections, such that I can never have both “Change Preset on Main Floor” and “Sleep” selected together. I also tried Action Type > Call Service > climate.set_preset_mode; I would get the Triggered toast, but no effect on the device.

I would mention that I did not get the expected Ecobee card following configuration within HA. I also did not get the four new Ecobee-specific Services that the component instructions mentioned would be added. However, as the thermostat cards seem to otherwise work with the device, I am assuming it is in fact integrated.

Any insight is appreciated.
