Which Somfy Motors We Specify
For curtain tracks we specify the Somfy Glydea range; it is quiet enough for master bedrooms, handles heavy blackout drapes, and accepts wired control. For roller blinds, Roman blinds and external screens we use the Somfy Sonesse family, sized to the tube and fabric weight rather than picked off a shelf.
Each motor comes in three control flavours: wired (running on a dedicated bus), RTS (Somfy's legacy one-way radio), and io-homecontrol (Somfy's two-way radio). RTS cannot report position back; io can, but still depends on a radio gateway sitting between the motor and the rest of the villa.
In a KNX villa we default to wired motors on a Somfy animeo or KNX shutter actuator. That way every blind is a first-class citizen on the same bus as lighting and HVAC, position is always known, and there is no radio gateway to fail in five years.
