Short answer: The Somfy DecoFlex WireFree RTS wall switch in two channels is part 1811068. It runs on a lithium coin cell, transmits RTS on 433.420 MHz, and drives two shades or two programmed groups from one wall plate. It pairs to any Somfy RTS motor or receiver through a remote the motor already knows, with no wiring and no electrician.
Two channels solve the most common wall-control job in a house: one switch at the bedroom door that runs the blackout shade and the sheer as separate layers, or a living room switch that splits the window bank from the patio door. The Somfy DecoFlex WireFree RTS 2 Channel Wall Switch, White (1811068) covers that job in a Decora-style footprint that sits beside a light switch and matches it.
Two zones on one RTS wall switch
Each channel button selects a transmitter slot. Press channel 1 and its LED lights, then press Up, Stop or Down, and every motor paired to channel 1 answers. Channel 2 works the same way for a second shade or group. Somfy's RTS Pocket Programming Guide adds one more trick: select both channels before the command, and the selected channels operate in a cascading fashion. One press then lowers the whole room.
Layouts installers use most:
- Bedroom: blackout roller shade on channel 1, light-filtering or sheer shade on channel 2.
- Living room: the window wall on channel 1 as a group, the slider drapery on channel 2.
- Patio entry: interior shades on channel 1, the exterior awning or solar screen on channel 2.
- Home office: east window on channel 1, south window on channel 2, so glare control follows the sun through the day.
Somfy lists five application groups for 1811068: awnings, exterior solar screens, interior window coverings (blinds, draperies and shades), pergolas and rolling shutters. The switch does not care which motor family sits behind the shade. If the motor or receiver speaks RTS, the DecoFlex drives it, including the "my" favorite position stored in the motor.

Motors and receivers the 2 channel switch runs
The fit rule is radio, not size or voltage. Every Somfy motor with RTS in its name accepts the switch, wired or battery. Two common partners:
- The Somfy Sonesse 30 RTS 24V DC Motor (1241142), a low voltage roller shade motor with the RTS receiver built in, rated 2 Nm at 25 rpm.
- The Somfy Sonesse ULTRA 30 WireFree RTS Li-ion Motor (1003310), a rechargeable motor with no wire to the wall. A battery motor plus a battery wall switch keeps the whole install free of electrical work.
A 120V motor with no radio inside still works through a receiver. The Somfy Universal RTS Receiver for 110V AC Motors (1810627) wires inline with the motor and stores up to 12 RTS transmitters, so the DecoFlex takes one of those slots and the original remote keeps another.
Zigbee motors ignore RTS, and a dry contact motor has no radio at all. Use 2 channel DecoFlex WireFree Zigbee keypads on Zigbee shades, and a hardwired switch station on DCT motors. Check the motor label for RTS before ordering.
Pairing the DecoFlex 2 channel to an RTS motor
Somfy's RTS Pocket Programming Guide applies its Telis multi-channel steps to the DecoFlex WireFree RTS switch and places the programming button on the front of the wall switch. You need a control the motor already knows, such as the original handheld remote.
- On the DecoFlex, press the channel button you want to assign. Its LED lights.
- On the already programmed control, select the same shade, then press and hold its programming button until the window covering jogs.
- Briefly press the programming button on the DecoFlex. The window covering jogs again, and that channel now drives the motor.
- Repeat steps 1 to 3 for each motor that belongs on the channel. Three motors on channel 1 turn it into a group button.
- Select channel 2 and run the same routine for the second shade or group.
Hold times and first-remote setup differ between motor generations. If a shade does not jog, open that motor's install guide in our Somfy spec library. The full add and delete routine for handhelds sits in our guide on how to pair, add and delete a Somfy RTS remote.
The "my" button works as on any Somfy RTS control. With the shade stopped, press MY/STOP and the shade travels to its favorite position. If the shade is moving, press MY/STOP twice.
Mounting and battery
The DecoFlex WireFree RTS needs no line voltage. Somfy pitches it for the spot beside an existing light switch, so the household finds shade control on the way in or out of a room. The switch mounts on its own bracket and takes a decorator-style plate, which lets it share a two-gang plate with the light switch.
The coin cell slides out of its holder. Fit a new 3V lithium cell, type 2450, with the polarity matched, and the switch keeps its channel programming in the motors. Cell life tracks how often the household presses the buttons, so keep a spare with the shade paperwork.
Somfy also builds DecoFlex in 1, 3 and 5 channel versions. The Somfy DecoFlex 1 Channel RTS Wall Switch, White (1810897) suits a bathroom or a single large window, and our DecoFlex comparison by channel count lays out the full family.
Add a timer or a hub to the same shades
RTS motors accept several transmitters, so the wall switch can share shades with automation. A Somfy Telis 1 Chronis RTS Timer (1805237) adds a daily up and down time on the same motors, while the DecoFlex stays on the wall for manual overrides.
For app control, scenes and voice assistants, pair the motors to a Somfy TaHoma Switch RTS and Zigbee Smart Hub (1871037). TaHoma sends RTS commands alongside the DecoFlex, so the switch at the door and the phone in the kitchen run the same two zones. Browse the full range of Somfy DecoFlex wall switches to match finish and channel count across the house.

FAQ
Does the DecoFlex 2 channel switch need wiring or a back box?
No. The DecoFlex WireFree RTS runs on a 3V lithium coin cell and sends radio commands, so nothing connects to line voltage. It mounts on its own bracket beside a light switch or on a bare wall and takes a decorator-style plate. An electrician enters the job if the motor itself needs new power, not for the switch.
Can one DecoFlex channel run several shades at once?
Yes. Pair two or more RTS motors to the same channel and that button moves them as a group. You can also select both channels before pressing Up or Down, and Somfy's guide says selected channels operate in a cascading fashion. A bedroom can then run blackout and sheer layers on their own or together.
Will the 1811068 work with Somfy Zigbee motors?
No. The 1811068 transmits RTS on 433.420 MHz, so it pairs with RTS motors and RTS receivers only. Zigbee shades need a DecoFlex WireFree Zigbee keypad, which uses the same decorator style. A TaHoma Switch speaks both radios and brings a mixed RTS and Zigbee house into one app.
Do I need an existing remote to program the DecoFlex?
Yes, in Somfy's standard method. Press and hold the programming button on a control the motor already knows until the shade jogs, then briefly press the programming button on the DecoFlex. On a brand new install with no paired control, follow the first-remote steps in the motor's own install guide, since that procedure varies by motor.
