01 — At a glance
What sets this motor apart.
This motor pairs ordinary 120 volt power with Zigbee 3.0 communication. The blind confirms its position in the TaHoma app, and the permanent power supply eliminates charging.
It delivers 4 newton-metres at 36 rpm, which covers the vast majority of interior blinds at twice the speed of battery motors.
It is the shortest connected motor in the 40 series: 20.24 in, for a minimum width of 22 3/4 in. Only the Sonesse 40 WT, which has no radio, is shorter.
4 newton-metres at 36 rpm

Environment
03 — Which blinds
The right blind for this motor.
22 3/4 in
Blind width
This motor requires a blind at least 22 3/4 in wide.
Below this width, the motor does not fit in the aluminum tube the fabric rolls onto.
This is the smallest width in the entire 40 series. The battery-powered Sonesse 40, with comparable power, requires 28 1/8 in.
What to consider before choosing
- Range reaches 200 m in open field, four times that of the Sonesse 40 RTS 120 V, which is limited to 50 m. Zigbee is not always the short-range protocol people assume: here, it far exceeds RTS.
- A power outlet must be accessible near the blind, or a circuit must be planned.
- A TaHoma is required for the app, schedules and voice control. No RTS remote is compatible: control goes through a Ysia device, a DecoFlex Zigbee or a TaHoma.
- For a very large or very heavy blind, the 409R2 version goes up to 9 newton-metres, at the cost of a slower speed of 14 rpm.
04 — Compatibility and power
How it's powered and controlled.
- Power supply
- Wired 120 V
- Plugs into an ordinary outlet or is hard-wired. The most powerful for its size.
- Protocol
- Zigbee
- Requires a TaHoma or Ysia bridge. Every continuously powered motor extends the home's Zigbee network.
- Compatible tube
- 2 in and 2 in heavy duty
- Family: 40 series
- Length
- 20.24 in
- Min. width: 22 3/4 in
05 — Frequently asked questions
What customers ask.
Which connected motor should I choose for a narrow window?
The 120 V Sonesse 40 Zigbee 404S2 goes down to 22 3/4 in wide, the smallest in the 40 series. Its battery-powered equivalent needs 28 1/8 in, because the battery takes up room in the tube.
Does Zigbee have a shorter range than RTS?
Not here. This motor reaches 200 m in open field, compared with 50 m for the 120 V Sonesse 40 RTS. The idea that Zigbee has a shorter range applies to battery motors, whose antenna is more limited.
Do I need a TaHoma?
Yes for the app, schedules and voice control. Without a TaHoma, a Ysia remote provides local control, but without remote monitoring.
How is it different from the 409R2 version?
The 404S2 offers 4 newton-metres at 36 rpm: fast and versatile. The 409R2 goes up to 9 newton-metres but drops to 14 rpm. The first suits most blinds, the second very large or very heavy shades.
Does it draw power at rest?
0.05 W on standby, ten times less than the RTS version. Its life-cycle carbon footprint is 42.4 kg.
Do you install in Montreal, Sherbrooke and the Eastern Townships?
Yes. Le Gars des Stores serves the West Island and Montreal, Vaudreuil-Dorion, the South Shore, the North Shore, western Laval and the Eastern Townships (Sherbrooke, Magog); elsewhere, depending on the project. We handle measuring, made-to-measure ordering, installation and programming.
