Home Assistant beta expands Matter fan control, adds timers

Beta update finally gives real fan speed control over Matter. In the 2026.5.0b3 release notes, developers unveil a set of practical upgrades aimed at tightening automation reliability and device compatibility, including exposing SET_SPEED for all fans via PercentSetting in Matter and new timer based triggers. Real-world testers will note the focus on making Matter capable devices behave more like traditional smart home gear, with fewer manual workarounds. The update also touches on mobile app behavior and testing improvements, signaling that this is less about flashy features and more about dependable, repeatable automations.

First, the big change for Matter users is the way fan speed is controlled. Exposing SET_SPEED for all fans via PercentSetting in Matter means automations can adjust a fan to precise percentages rather than only turning it on or off. For households with mixed Matter and non Matter devices, this can simplify scenes that previously required workarounds or vendor specific apps. It also raises questions about compatibility and firmware requirements, since not every Matter bundle supports the same percentage granularity yet. In hands-on terms, this is the kind of improvement that reduces friction when you are choreographing air flow across multiple rooms.

The update also expands automation triggers with a timer option that many power users have long wanted. The addition of trigger timer.time_remaining gives automations a natural way to react as countdowns wind down, enabling use cases like timed ventilation or scheduled alerts without scripting hacks. Alongside timer triggers, the release adds media player related triggers such as media_player.unmuted and a broader set of media_player volume triggers and conditions. Together these changes tighten the feedback loop between what users see in the app and how automations respond in real time.

On the reliability front, the notes flag a concrete improvement for energy data handling. The project catch is that energy data updates can encounter errors that previously surfaced as flaky failures; the beta now treats certain errors as retryable, offering more resilient data collection for dashboards and automations that rely on energy usage patterns. That arguably matters most for households with solar, EV charging, or dynamic climate control where misreadings can derail a scene. It is the kind of behind the scenes hardening that often pays off in quiet stability.

Finally, the release signals ongoing maintenance and forward momentum. The notes mention bumping intents to 2026.5.5 and updating frontend to a recent build, underscoring that this beta sits inside a broader cycle of compatibility fixes and UI polish. There are also several small quality improvements, such as improved tests for mobile_app device tracking and automation options, plus exclusions for incompatible entities in humidity and temperature automations. For users, the takeaway is that this is a practical, not flashy, refinement pass that should translate into fewer edge cases and more predictable behavior in daily use.
