These Bluetooth Single/Double Rocker Wall Switches are universal energy harvesting wireless switches in the European 55 x 55 form factor. They are based on the maintenance free, self powered Bluetooth Low Energy (BLE) pushbutton transmitter module PTM 215B.

Long or short rocker presses can be calculated by the receiver, enabling switching, dimming control or jalousie control including slat action.

Both single and double wall switches are available.
