Common questions
What is the Sonesse 40 WireFree Zigbee motor?
The Sonesse 40 WireFree Zigbee (1245993) is a battery-powered Somfy tubular motor for interior blinds and shades. It communicates over Zigbee 3.0, and a built-in rechargeable lithium-ion battery powers it, so the window needs no wiring. Somfy rates it at 4 Nm of torque.
How do I charge it, and how often?
Charge it through the USB-C port. Somfy says the battery needs a recharge about once a year on a reference blind. Magnetic and solar charging are options, and the Somfy USB-C Magnetic Adaptor (9028564) fits this motor.
Can I control it from my phone or a voice assistant?
Yes. Pair it with the Somfy TaHoma Switch hub (1871037) for app control and voice control through Amazon Alexa, Google Home and Apple Home. Zigbee is two-way, so the TaHoma app shows shade position and battery level.
Which remotes and wall switches work with it?
Somfy Zigbee controls pair with it, including the Ysia 1 (1871153) and Ysia 5 (1871154) Zigbee remotes and DecoFlex WireFree Zigbee wall switches such as 1871573. Somfy rates the motor's radio range at 262.48 ft in open field.
What tube size does it fit?
The motor suits tubes with an internal diameter of 38mm (1.5 in) or more. Compatible parts in this store include the 40mm octagonal tube (1781154), the LS40 crown and drive set (9012224) and the Sonesse 30-40 motor plate for RollEase 360 brackets (9026001).
