Top open-source platform Home Assistant has announced the addition of support for Matter dishwasher alarms and battery storage devices, further advancing its position to provide a whole-house Matter experience.
The new features come from regular community contributor @lboue, who has previously helped to add water heater, pump, and mounted modules to Home Assistant and other open-source smart home projects.
Details on the addition
While dishwashers were already supported by Home Assistant, the latest version introduces two new entities: Door alarm and Inflow alarm. These sensors can be utilized for extensive automation with lights, speakers, and other devices. For example, you could set up an automation so that lights flash or a notification sounds if the dishwasher door is left open.
The screenshot provided in the announcement demo showcases how the device will appear in Home Assistant, using a virtual device created with Google Matter Virtual Device.
Battery storage device support is an extension of the platform’s existing Matter power meter integration. According to the Matter specification, when connected to Home Assistant, you’ll be able to monitor whether your battery system is charging, discharging, or running on battery, as well as check the current power output and total energy usage. Additionally, users can view and control the battery’s energy management mode directly from the Home Assistant dashboard.
Both new features are included in the Home Assistant 2025.7 beta update, which is available for early adopters. If you’re interested in testing these capabilities, make sure to perform a full backup before enabling the Beta update option in the system setting and Matter server add-on. The official public release is scheduled for early July, as part of Home Assistant’s regular update cycle.
Ongoing community work matters
This kind of contribution continues to bridge different smart home devices together with Matter. For example, you can easily integrate smart home devices from mainstream brands into Home Assistant, then use the Matterbridge Home Assistant plug-in to port them over to any Matter-enabled platform locally without any paid subscription.
Devices such as Gen 3 Shelly, which don’t support power metering via Matter, can also be enabled through Matterbridge. This is all possible thanks to the open-source nature of both the Matter standard and the Home Assistant community.
