Common questions
What is the Roll Up 24 WireFree RTS motor?
Part 1240278 is a small Somfy battery motor for light interior shades. Somfy lists blinds, roller, roman, woven, zebra and layered shades as applications, and its built-in rechargeable lithium-ion battery removes the need for wiring.
What torque, speed and tube size does it need?
Somfy rates it at 0.55 Nm and 38 rpm. The motor measures 0.83 in across and needs a tube with an inside diameter of at least 0.87 in. The R24 Crown and Drive for RollEase 28mm tubes (9025712) is a listed match.
How do I recharge it?
Somfy offers a magnetic charging connection for its V2 Li-ion motors. Listed accessories include the Magnetic Adapter (9028562), Magnetic Rigid Cable (9028560), 8 in Extension Charging Cable (9021131) and WireFree Li-ion Plug-in Charger (9025166). An LED warns when the battery runs low.
Can solar power keep it charged?
Yes. Somfy offers a solar charging option, and the 12V DC WireFree V2 Solar Pack (9027294) is one of the motor's listed accessories. Solar charging cuts trips to recharge shades on tall or hard-to-reach windows.
Which remotes and switches work with it?
Any Somfy RTS transmitter, including Situo 1 and 5 channel remotes (1870571, 1870575) and DecoFlex RTS wall switches (1810813, 1810897). Somfy lists 12 channels and an RTS range of 656.2 ft in open field.
Can I control it from my phone or a voice assistant?
Yes, through a Somfy TaHoma switch (1871037). RTS is one-way radio, so the app sends commands but cannot report the shade's position. The motor uses a slow start and stop for smooth shade movement.
