Events and automation triggers
Presses on this device reach Home Assistant as device triggers through
the
Zigbee Home Automation
integration, which you pick in the automation editor after pairing.
The button list, and whether each button also becomes an
event
entity, comes from what the device reports at pairing time, so it
appears once the device is on the network.
Read from Home Assistant 2026.8.3: the integration declares these trigger types, and core holds no per-model button list for this device.
