Question about Lenovo Smart Clock Essential

Only small things can be set via the Home app: Something like display in 12 or 24 hour format or the volume of the alarm tone. Otherwise, what all hubs can set.

The alarm times can be set on the device with the buttons if you want, but the easiest way is to set the alarm by voice command: "Set the alarm for every Monday to Friday at 7am" for example. Or "Set the alarm for 9 a.m. tomorrow."
