What's New in Home Assistant

2026.9.1

September 9, 2026

New * Apple Health sleep sensors (Labs) * Apple Watch as its own device — separate registration with battery reporting from the watch (Watch sensors require opt-in on watch settings itself) * Manage Storage screen under Settings › Debugging * “Create deeplink” gesture action * Gas and battery added to the Energy widget * Client-certificate prompt when a server requires (or refuses) one Improved * Widgets: entity icon colors, tap behaviors, and tile icon actions now match the frontend; "Show states" is on by default and out of beta; Common Controls can be filtered by domain * Expanded Dynamic Island layout for Live Activities * CarPlay actions have error handling and timeouts Fixed * Launch crash on iOS 16 caused by nested navigation stacks * Quick Access items switching server when entity IDs collide * Watch entity states not updating, and mTLS camera streams on Apple Watch * Lock screen widgets not running scripts, and entity states missing on some widget tiles * Frontend reloading on rotation * Legacy watch complications showing an icon or shrinking text; icons missing from the bundled icon font * Stale sensor values overwriting newer ones * Clipboard writes failing silently from ingress panels (like Music Assistant) * Network state lost when Wi-Fi info is unreadable

User reviews

Slower than web interface and randomly crashes

Months later, new versions just keep getting worse. Bloated and unreliable excrement
Typical of the pathetic, half finished, badly designed, poorly thought out mess that Frenks Fan Club produces.
STILL no security or decent multi user capability.
The entire home assistant system can only be described as the best of a (very) bad lot.
Every update just brings a different set of bugs, usually without fixing anything meaningful.

Thanks for reporting the issue, in here I cannot help you, but if you reach out to our official support channels like discord or github I can help you out.

One to rule them all

Home Assistant is the smart home platform I've been hunting for 10+ years.

Apple Home? Check. Google Home? Check. Alexa, SmartThings? All tried them. None deliver what HA does: total control over your devices without compromising privacy.

The killer feature: Everything runs locally. Your data stays yours. No cloud dependency. No telemetry mining. This is what smart home should feel like.

Warning: HA is powerful, which means it's not plug-and-play easy. Invest the time to learn it but you won't regret it.

Massive respect to the developers keeping this open, local-first without compromising privacy. 🙌

Bluffant

Incroyable, je n’avais pas imaginé la puissance de cet outil. J’en suis au tout début et je m’émerveille tous les jours du potentiel de HA. C’est bluffant. Bravo à tous ceux qui ont permis de développer une telle application.

Thank you!
