Crown = slats
Rotate the Digital Crown to tilt slats from open to fully closed. Haptic feedback at every stop.
For Apple Watch
Your blinds, on your wrist.
Control Somfy exterior venetian blinds straight from Apple Watch. Tilt the slats with the Digital Crown, drag down to close. No iPhone, no hub, no bridge needed at runtime.
Built for the wrist
Touch nothing else.
Drag = closure
A vertical swipe sets exact closure 0–100%. Closure and tilt commit together, one command, one motor cycle.
Scenes for everyday
"Morning", "Shade", "Night". Save multi-blind presets and run them with a single tap. Edit on iPhone, run from the wrist.
Truly standalone
The watch talks to Somfy cloud directly. Leave your iPhone behind, your blinds still listen.
A whole house at a glance
One swipe per blind. Or all of them at once.
List every blind on your Somfy account, themed with the colour you actually have on your house. Open the All view to crown-control every blind in the room in parallel. Stop, My, set tilt, they all answer.

Good to know
Frequently asked.
Which blinds work?
Any Somfy ExteriorVenetianBlind device registered on a Connexoon, TaHoma or Cozytouch box. If you can open/close them in the Somfy app, Slatly will see them.
Do I need an iPhone nearby?
Only the first time, to sign in. After credentials sync via iCloud Keychain, the Watch app runs fully standalone over LTE or Wi-Fi.
Where are my credentials stored?
In Apple's iCloud Keychain, end-to-end encrypted under your Apple ID. The app itself never sends them to any third party, only to Somfy's official OAuth endpoint.
Is it open source?
Yes. The Swift code, the OverkizKit library, and this website are all on GitHub. Contributions and translations are welcome.
When is it on the App Store?
A TestFlight build is in active polish. Public App Store release follows once the iCloud sync capability work is signed off. Join the TestFlight to get early access.
