How to Choose a Somfy Motor for an Existing Roller Blind
Somfy motors can often be installed into an existing roller blind without replacing the fabric. The deciding factors are the roller tube, blind load, available space, brackets, power supply and the Somfy control system you want to use.
Start with the existing tube
Identify the tube’s internal profile before choosing a motor. The motor must fit physically and use the correct crown and drive. If the existing tube is too small, unsuitable or not stiff enough for the blind, it may need to be replaced.
Then choose the Somfy system
Rechargeable RTS motors are usually the simplest retrofit option. Hardwired 240V motors suit permanent powered installations and larger loads but require a licensed electrician. Zigbee motors suit compatible connected-home projects planned around Zigbee controls and TaHoma.
What information is needed?
Send Motorise My Blinds the blind width and drop, fabric type, a clear photo of the tube end and internal profile, and whether you prefer rechargeable or hardwired power. We can then narrow the choice to the Somfy motors and components we actually supply.
