Signal range

Typical range

The typical point-to-point indoor range is ± 10 m. The meshing capability of 230 V powered wireless mesh devices can extend the RF range.

Materials and obstructions

Radio waves can be attenuated by materials inside a building or room. The maximum point-to-point RF range of the connected switch to a wireless receiver depends on:

• The materials used in the building or room,

• The indoor position of the connected switch and

• Sources of interference.

The table below provides an overview of common materials and corresponding losses:

Installation position

To ensure reliable wireless communication, avoid installing the wireless module in the following locations:

• In narrow rooms with thick walls.

• On the same wall as another wireless repeater or receiving module.

• Less than 110 cm above floor level (recommended mounting height: 110 cm).

• On metal surfaces, damp surfaces, or areas with high humidity.

• In RF "dead spots" caused by signal reflections or attenuation from nearby conductive materials or obstacles, such as metal cabinets, doors containing metallic foil, or objects with a high water content (for example, aquariums).

Maintain a minimum separation distance of 2 m between any wireless module (including the Smart Hub) and other RF transmitters, such as Wi-Fi access points or routers. The same minimum distance should be maintained from equipment that may generate electromagnetic interference (EMI), including electric motors, pumps, electronic LED drivers, solar inverters, and residential battery energy storage systems.

Sources of interference

Wireless modules are generally immune to interference from low-power electronic devices, including DECT telephones, smartphones, Wi-Fi access points and routers, analogue radios, electronic ballasts, control equipment, televisions, audio/video equipment, computers, and remote controls.

The wireless network uses a robust RF communication protocol with self-healing mesh functionality, enabling reliable communication even in environments with moderate levels of electrical noise. However, high-power electrical or electronic equipment may occasionally degrade RF performance. If interference is suspected, identify and eliminate the source where possible. Where this is not practical, improve network coverage by relocating the wireless module or installing an additional repeater node, such as a compatible mains-powered (230 V AC) wireless module.

Installing the connected switches

Step 1 - Connecting

Connect the supply voltage and the devices to be controlled, according to the wiring diagram.

Step 2 - Addressing

Onboard and configure the wireless module using the Niko Home Control programming software. Add, configure, and assign the wireless modules in accordance with the standard workflow and configuration procedures defined within the software. For more details, see:

Troubleshooting and maintenance

Troubleshooting

Wireless network reset

When the reset command is executed, only active wireless devices receive the command. These devices leave the network, and their internal network configuration data is cleared, allowing them to be added to another wireless network without requiring a manual factory reset.

Active devices typically include 230 V-powered wireless modules, which continuously monitor the wireless network. Battery-powered devices are only active during operation and for approximately 90 seconds afterward.

Inactive wireless devices do not receive the reset command. These devices must be manually factory reset before they can be added to a different wireless network.

The reset function clears the complete wireless network configuration, including the network channel and network ID stored in all active wireless devices.

Wireless Device Firmware Upgrade Procedure

When a firmware upgrade is available, a notification is displayed in the latest version of the Niko Home Control programming software or the Niko Home app.

Over-the-Air (OTA) upgrades are not indicated by the device feedback LEDs. However, if the wireless connection is interrupted during the upgrade process, the LED status may change to indicate the communication issue.

All wireless devices are upgraded automatically in sequence. The upgrade process starts within a maximum of 6 hours after the smart hub or connected controller has been updated.

If an upgrade fails, a notification is displayed in the Niko Home Control programming software or the Niko Home app. The wireless device remains operational and continues to use the previously installed firmware version.

For wireless devices used in systems without a Niko Home Control connection, firmware upgrades can be performed manually using the available OTA firmware files at https://download.nikogroup.eu/nhc2/release/upgrades/ota/index.json

Manual network reset

Method 1 - Using the K1 button

Proceed as follows:

1. Press the K1 button briefly five times to perform a factory reset and initiate network pairing mode.

2. After the factory reset, the device enters network pairing mode. The pairing window remains active for 180 seconds or until the device is successfully added to a new wireless network.

3. Verify the LED status:

   • The LED flashes rapidly after the factory reset, indicating that the device is in pairing mode.

   • If a wireless network is detected, the red LED flashes slowly twice, followed by 180 seconds of rapid flashing while the device searches for a network connection.

   • Once the network is open and pairing is successful, the red LED remains on for 3 seconds and then switches off.

The device is now reset and successfully connected to the wireless network.

Method 2 - Using power reset

Proceed as follows:

1. Reset the power of the device 5 times as indicated in the diagram below:

   

2. Observe the LED status during network pairing:

   • The red LED flashes slowly twice when a nearby wireless network is detected.

   • The LED then flashes rapidly for up to 180 seconds while the device attempts to join the network.

3. When the network accepts the device and pairing is successful:

   • The red LED remains continuously illuminated for 3 seconds.

   • The LED then switches off to indicate that the pairing process has been completed.
