Common questions

What is the Sonesse 28 WireFree RTS motor?

Part 1241230 is a compact Somfy battery motor for interior shades, including sheer and layered styles. It runs on an external rechargeable lithium-ion battery pack, so no power wiring runs to the window.

Which battery and charging options work with it?

It takes an external 12V lithium-ion pack such as the Rechargeable Lithium-ion Battery Pack (9021217), and the WireFree Li-ion Plug-in Charger (9025166) recharges it. The 12V DC WireFree V2 Solar Pack (9027294) keeps the battery topped up, and a 12V DC power supply can run the motor without a battery.

How loud is it?

Somfy rates it at 49 dB and builds it to its Designed for Silence standard. The small motor head suits smaller windows, and the motor offers adjustable speed for smooth movement.

Which remotes and switches work with it?

Any Somfy RTS transmitter, including Situo remotes (1870571, 1870575), the Telis 16 Channel (1811081) and DecoFlex RTS wall switches. The Situo 5 Variation RTS Pure II (1811612) adds speed control. Somfy rates RTS range at 656.2 ft in open field.

Can I control it from my phone or a voice assistant?

Yes, through a Somfy TaHoma switch (1871037), which links to Amazon Alexa, Google Home and other platforms. RTS is one-way radio, so the app sends commands but cannot report the shade's position.

Which crown and drive adapters fit?

The compatible parts on this page include the R28 Sonesse Crown & Drive Kit for Silhouette and Hunter Douglas shades (9025816) and the RollEase 1.25 in Crown & Drive (9025815). Match the adapter to your shade maker's tube before ordering.
