Sunea RTS CMO motor -- cassette and semi-cassette awning specialist with manual override
The Sunea RTS CMO motor is Somfy's dedicated motor for cassette, semi-cassette, and standard awnings. It automatically re-settles its limits as the fabric stretches over time, and includes a compact manual override crank so the awning can still be operated by hand if power is lost.
Benefits
- Automatically resets limits as awning fabric settles or stretches
- Compact manual override (CMO) crank keeps the awning usable during a power outage
- Soft-close function reduces stress on awning arms
- Electronic obstacle detection stops the motor if a blockage occurs
- Settings and programming are retained in the motor's memory

Common questions
What is the Sunea RTS CMO 550R2 used for?
Part 1118210 is Somfy's motor for cassette, semi-cassette and standard retractable awnings. It resets its limits as the awning fabric settles, uses a soft-close function to ease stress on the arms, and stops when it detects an obstacle.
What does CMO mean?
CMO stands for compact manual override. The motor head accepts a crank, so you can open or close the awning by hand during a power outage. This site carries the Somfy CMO Awning Override Shaft, 100mm with Geiger eye (9707287).
What are its torque, speed and noise ratings?
Somfy rates the Sunea 550R2 at 50 Nm of torque and 14 rpm, with a noise level of 55 dB. It has an external diameter of 1.97 in and fits tubes with a minimum inside diameter of 1.85 in.
How do I connect power?
The motor runs on 120V/60Hz AC at a rated 2.1 A and 240 W. Somfy ships it with a 1.31 ft lead that ends in a fast connector. Add a Somfy 3 wire fast connector cable with plug, such as the 10.4 ft (9020791) or 24 ft (9020793) length, to reach the outlet.
Which controls and sensors work with it?
Any Somfy RTS transmitter pairs with it, including Telis RTS patio remotes, Situo RTS remotes and DecoFlex RTS wall switches, up to 12 channels. For wind protection, the Eolis 3D WireFree RTS wind sensor (1816081) mounts on the awning and signals it to retract in strong gusts.
Can I run the awning from an app?
Yes. The Somfy TaHoma Switch hub (1871037) controls RTS motors from a phone app and supports schedules and voice assistants. RTS is one-way radio, so the app sends commands without reading back the awning's position.
