6. RADIO PLANNING GUIDE
As a rule of thumb, try to achieve a direct line of sight between the Niko dimmer switch and the Bluetooth
®
receiver. If this is not possible, and there are one or more walls between the devices, the RF signal should penetrate
the wall(s) as straight as possible. We recommend using a mobile Bluetooth ® test device to determine the optimal indoor mounting position. When the radio coverage is not sufficient, try relocating the Niko dimmer switch or
use a Bluetooth
®
RF repeater.

The maximum indoor RF range depends on:
• the materials used in the room (radio waves can be attenuated by indoor materials) (see §6.1 below)
• the indoor position of the dimmer switch (see §6.2 below)
• sources of interference (see §6.3 below)
6.1. Materials and obstructions
Material Range Reduction (versus a direct line of sight)
Wood, plaster, uncoated, without metal 5 – 20%
Brick, concrete without iron, chipboard 20 – 40%
Ferroconcrete, hollow lightweight walls filled with insulating wool on metal foil, metallic heating insulation
sheets, metallic surfaces, glass with a metal coating, floor heating systems, metal faceplates
40 – 90%
Note that a human body can obstruct the Bluetooth
®
radio path. Take caution when a lot of people are in a room.
6.2. Position
Avoid installing the dimmer switch:
• in a narrow room with thick walls
• on the same wall as the receiver
• close to the ground
• on a metal or moist surface or in a damp environment
• in so-called ‘dead spots’, caused by radio reflections from nearby conductive materials or large obstacles
6.3. Sources of interference
Respect a minimum distance between devices listed below and the Niko dimmer switch.
Devices Minimum distance
Magnets and ferromagnetic materials 6 cm
Low-power electronic devices (e.g. DECT telephones, smartphones, WLAN routers, analog radios, electronic
ballasts, controllers, TVs or computers)
50 cm
A high-power electronic device in a room can interfere with the radio telegrams of the Niko dimmer switch. Even with installations where the switch and the receiver are located within a direct line-of-sight or a range of fewer
than 10 m from one another. Identify the interfering source and remove it. When removal is not possible, consider relocating the Niko dimmer switch or use a Bluetooth
® RF repeater.
