+##### Matter

+White series switches only have a single LED and do not support effects. Lampie will do the following for these switches:
+
+- All will simply indicate to enable the notification (besides `CLEAR`)
+- If [individual LEDs](#full-led-configuration) are configured, the first LED settings will be used

+Unlike the Blue series switches under ZHA, there is no way to receive events for when a notification expires (it only supports, for instance, when the config button is dobule pressed via a state change on `event.<switch_id>_config` with `event_type="multi_press_2"`). This may be supported in the firmware and not yet available for end user consumption.
