Figure 1: Attach RAK9154 to solar panel- Connect the cable of the solar panel to the PV input connector of RAK9154. Install two (2) M6 screws to the mounting plate with a clearance of about 3 mm.
Figure 1: RAK9154 and Solar Panel Connection- Suspend the solar panel on the mounting bracket, adjust its angle and direction, and then tighten the two (2) M6 screws along with the remaining two screws.
Figure 1: Install the solar panel combination- Connect Sensor Hub and RAK9154. Use a cable to link the remaining connection port of the Sensor Hub to the lithium battery Output 1 SP11 connection port of RAK9154.
When connecting to RAK9154, ensure that the Sensor Hub is connected to the Output 1 connection port.
Figure 1: Connect Sensor Hub and RAK9154- Once the connection is complete, the Sensor Hub is ready to be powered up.
12 VDC Power Supply Installation
- Connect the power adapter to the external power cable of the Sensor Hub using a circular DC connector.
Figure 1: Power adapter connection- Connect the external power cable to the Sensor Hub using the SP11 connector.
- Align the white dot symbol on the SP11 connector plug of the external power cable with the white dot symbol on the Sensor Hub SP11 connector socket and push the plug firmly into the socket.
- After the plug and socket are connected, tighten the locking nut to secure the connection of the SP11 connector. The external power cable can connect to any Sensor Hub connection port.

Sensor Hub Configuration
Power Up Sensor Hub
After installing all hardware components, connect the power supply. If the power supply consists of a solar panel and a battery, the device will power on automatically once all hardware has been installed.
To prevent damage to the device, refrain from powering up the Sensor Hub before connecting it to the sensor. It is advisable to use the 12 VDC adapter provided with the Sensor Hub for optimal performance.
Connect Sensor Hub to WisToolBox
- Download and install the WisToolBox app on your smart mobile device. The WisToolBox app is available for download from the Apple App Store and the Android Google Play Store.
- Initiate the app and confirm that NFC and Bluetooth are enabled on your mobile device. Click on START.
Figure 1: Start the app- On the Select connection mode menu, choose NFC Activation.
Figure 1: Select NFC Activation- Select the Sensor HUB option in the device selection interface to establish a connection.
Figure 1: Select Sensor Hub- Click the CONNECT button to initiate the scanning process for devices.
Figure 1: Click on the CONNECT button- Hold your mobile device close to the N symbol on the Sensor Hub device.
Figure 1: Scanning in progressThe detection of the Sensor Hub device indicates that the device has been successfully powered up.
Figure 1: Scan Successful- After the connection is established, there will be a synchronization of device data. This process may take some time.
Figure 1: Sync Device- By default, if no connection is established within 30 seconds, the BLE broadcast of the Sensor Hub will automatically shut down. To establish a connection, connect the RAK device immediately after turning on the power or restart the power.
- Certain Android smartphones may necessitate enabling GPS to connect to BLE. Enabling GPS does not involve the use or sharing of sensitive information with the app.
- Upon completion of data synchronization, the app will automatically transition to the SENSOR HUB INFO page.
Figure 1: SENSOR HUB INFO page- While on the SENSOR HUB INFO page, configure the Uplink Settings according to the selected network.
Figure 1: Uplink Settings option- Once configured, click SAVE SELECTION, and then the APPLY button to implement the configuration options.
Figure 1: Apply the configuration optionsAfter a few seconds, the synchronization progress will be completed, concluding this process.
