Home Assistant 2026.10 adds settings for independently enabling audible and visual alarms on compatible Matter leak sensors, plus one-touch locking on supported locks. Leak-alarm configuration requires Boolean State Configuration support and is not a command to trigger the alarm manually. Locks must expose EnableOneTouchLocking for that setting to appear. PIN-user management dates to version 2026.4 and is not newly introduced here. The article’s ESP32 mock device lacked some alarm attributes, so deployment should begin by checking the attributes and manufacturer support of the actual hardware.
