Slatly vs the official Somfy app
A short, honest comparison of the two options for controlling Somfy blinds from an Apple Watch. Written by Slatly's developer — read it that way.
TL;DR
The official Somfy app is the right tool for first-time setup, firmware updates, and account management. Slatly is the right tool for the daily wrist-driven experience — Digital Crown tilt, drag-to-close, scenes, standalone over LTE, and a real complication that opens the app from any watch face.
What both apps do well
Both apps talk to the same Somfy cloud (Connexoon, TaHoma, Cozytouch). Both move your blinds. Both work with the box you already have installed.

Where each one wins
Use the official Somfy app for:
- Initial pairing of the TaHoma / Connexoon / Cozytouch box.
- Pairing new motors with the box.
- Firmware updates for the box and devices.
- Voice setup via Alexa or Google Assistant (Somfy cloud integration).
- Multi-user permissions and Family sharing of the Somfy account.
Use Slatly for:
- Day-to-day tilting and closing of blinds from the wrist, hands-free.
- Triggering scenes from a watch tap — Morning, Shade, Night — instead of pulling out a phone.
- Standalone use during a run, in the garden, or anywhere the iPhone is not on you.
- Having a Slatly complication on your watch face so launching is one tap.
- Knowing exactly what the code does — read it on GitHub.
"Can I use both?"
Yes, and most users do. They are not in conflict — both read and write through the same Somfy account. Set up your box with the Somfy app, then install Slatly for daily use.
"Will Slatly damage my Somfy installation?"
No. Slatly only sends the same documented commands (setClosureAndOrientation, setOrientation, my, stop, open, close) that the official Somfy app uses, through Somfy's official OAuth endpoint. No firmware-level access, no direct radio, no local-network protocol bypass.
