The schedule function is fully available exclusively via the Aqara Home app. This function requires Zigbee mode and an Aqara Hub.
Basic functions can be used without a hub (Thread and Google Home only). These include
Manual setting of the temperature
Automation of temperature control via Google Home
Voice control
Grouping of multiple thermostats
Integration in Google Home via Matter/Thread
Complex schedules are not natively available without a hub Advanced functions such as geofencing, window detection, external sensors and local schedules require Zigbee mode and an Aqara Hub.
The device also works without Aqara Gateway if it is connected via a Thread Border Router (e.g. HomePod mini, Apple HomePod 2nd Gen or Amazon Echo from 4th Gen). In this Thread mode, no Aqara Hub is required, but the range of functions in the Aqara app is limited. An Aqara Zigbee Hub is required for the full range of functions.
