Crown = slats
Rotate the Digital Crown to tilt slats from open to fully closed. Haptic feedback at every stop.
For Apple Watch
Your blinds. Always at hand.
Control your exterior venetian blinds straight from Apple Watch — using the Somfy TaHoma, Connexoon or Cozytouch box you already own. Tilt the slats with the Digital Crown, drag down to close. No iPhone needed at runtime, just the watch and your home Wi-Fi.

Meet Slatly
A tiny app with one job.
Just the Apple Watch. The crown tilts the slats, a swipe closes them. No remote, no phone.
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
After the first sign-in, the watch talks to your TaHoma box through the Somfy cloud directly. Your iPhone stays home; the blinds still answer.
A whole house at a glance
One swipe per blind. Or all of them at once.
List every blind paired with your TaHoma box, 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 motorised exterior venetian blind paired with a Somfy TaHoma, Connexoon or Cozytouch box — Somfy itself, plus io-homecontrol / RTS partner brands (Profalux, Asio, Eltako and others your box already supports). If they show up in the Somfy / TaHoma app, Slatly will see them.
Do I need an iPhone nearby?
Only the first time, to sign in. After credentials sync via iCloud Keychain (or via the built-in Watch hand-off), the Watch app runs fully standalone over LTE or Wi-Fi.
Do I need extra hardware?
No new hardware. Slatly reuses the Somfy TaHoma, Connexoon or Cozytouch box that already controls your blinds. No bridge, no second hub.
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.
Is it on the App Store?
Yes — Slatly is live on the App Store for $0.99. One-time purchase, no subscription.
Can I control Somfy blinds from Apple Watch without the iPhone?
Yes, that's exactly what Slatly is built for. After a one-time iPhone sign-in, the Watch app runs fully standalone over LTE or Wi-Fi. Your iPhone can be downstairs, off, or out of Bluetooth range.
What Apple Watch apps work with Somfy TaHoma?
Slatly is purpose-built for the Somfy ExteriorVenetianBlind class on Connexoon, TaHoma and Cozytouch boxes — and it's the only third-party watchOS app that drives them standalone, without proxying every command through the iPhone.
How is Slatly different from the official Somfy app?
Slatly focuses entirely on the Apple Watch experience: real Crown-driven slat tilt, drag-to-closure gestures and standalone operation without the iPhone. The Somfy app remains useful for box setup and firmware updates; Slatly is the daily driver from your wrist.
Why we built it
Even the cat wants a peek.
You have motorised blinds. You have an Apple Watch. The only thing missing is the easy way between them. Slatly is the easy way — twist the crown, see the world (or close it back).
