Home Assistant's 2026.10 beta, first released September 30, 2026, adds separate sound and light settings for supported Matter leak sensors. The beta release notes name IKEA KLIPPBOK as an example. Owners can configure the sensor's alarm modes from Home Assistant, but this is still an opt-in beta feature: the October 5 2026.10.0b1 release remains a prerelease.
The useful change is control over how a leak sensor warns you. The implementation adds separate configuration switches for audible and visual alarms, preserving one setting when you change the other. They enable or disable those alarm modes; they are not buttons for remotely sounding a siren. If you bought a sensor mainly to hear a leak from the next room, keep its audible warning enabled.
The sensor must expose the setting
Home Assistant creates these controls only when the accessory exposes the required alarm features and command. A Matter logo alone does not guarantee either switch. Comparing the stable 2026.9.4 integration with the October beta code confirms that the settings are new to this beta, rather than a previously hidden stable option.
The beta also adds a one-touch locking setting for Matter locks that expose it. That setting determines whether a single keypad touch can lock the door; it does not add keypad hardware or promise support for every Matter lock. The release notes do not give a complete model and firmware list for these controls.
For KLIPPBOK owners, this is an extra configuration option, not a reason to replace a working sensor. Connected use still needs Home Assistant's Matter integration and a Thread border router. Matterhome has not tested the beta or verified the controls across regional KLIPPBOK firmware versions.
Home Assistant OS users who want to test can open Settings > System > Updates, select the three-dot menu, choose Join beta and install the offered update, following the official beta instructions. For an everyday installation that depends on leak alerts, wait for stable release notes before changing channels. Home Assistant says beta features can still change or be removed before release.
