| Overview
SmartNode uses Bluetooth Low Energy (BLE) to communicate with supported 75F wireless sensors and receive their available sensor data for supported system functions. Wireless sensors can be paired with SmartNode and assigned to individual sensor slots for identification and management.
SmartNode is responsible for:
- Discovering and pairing supported wireless sensors.
- Establishing and maintaining connections with paired sensors.
- Receiving sensor data and status information from connected wireless sensors.
- Making the received sensor data available for supported system functions.
The SmartNode supports a maximum of 8 wireless sensor connections.
| Supported wireless sensors
| Sensor type | Maximum Paired Sensors | Firmware Version |
|---|---|---|
| 75F Wireless Door Sensor | 6 (Recommended 4) | >v1.1 |
| 75F Wireless Multi Sensor | 6 (Recommended 4) | NA |
Current Implementation limitation: The 75F Wireless Door Sensor can be paired with the SmartNode, but its sensor information is not currently exposed through the Connected Sensors page.
| Wireless sensor pairing
The SmartNode provides eight wireless sensor slots, identified as WS1 through WS8.
To pair a wireless sensor:
- Open Installer Options and Select Wireless Sensors.
- Select an available sensor slot.
- Put the wireless sensor into pairing mode and SELECT the required sensor
- Verify the connection status.
During the pairing process, the SmartNode can display the following states:
| Status | Description |
|---|---|
| CONNECTING | The SmartNode is establishing a connection with the selected wireless sensor. |
| CONNECTED | A Bluetooth connection has been established with the wireless sensor. |
| PAIRED | The wireless sensor has been successfully associated with the selected sensor slot. |
| Connected Sensors
The Connected Sensors page displays the connected wireless sensors and their available sensor data
| Wireless Sensor Diagnostics
The Connected Sensors page provides access to a sensor’s current sensor data and diagnostic information. Selecting a connected wireless sensor opens its individual sensor information.
| Locate Me
The Locate Me function identifies the physical wireless sensor associated with a selected paired sensor entry.
Note: The 75F Wireless Door Sensor does not support the Locate Me feature.
| To locate a paired wireless sensor
- Open Installer Options and Select Wireless Sensors.
- Select the required paired wireless sensor, then select LOCATE
- Identify the physical sensor by observing its RGB LED, which blinks to indicate the selected sensor.
- Select STOP to terminate the Locate Me operation.
| Locate Me Operation
When LOCATE ME is selected for a paired wireless sensor, SmartNode initiates the Locate Me operation for the selected sensor.
The operation has the following behavior:
- The selected wireless sensor indicates its identity by blinking its RGB LED for up to 60 seconds.
- The Locate Me operation has an overall 2-minute timeout.
- If the sensor is not located within 2 minutes, the operation terminates and normal wireless sensor scanning resumes.
- STOP can be selected to terminate the operation before the timeout.
- When the operation is terminated, SmartNode resumes normal wireless sensor scanning and communication.
- If the expected LED indication is not observed, terminate the operation using STOP and initiate LOCATE ME again.
- Once the Locate Me operation is terminated, LOCATE ME can be initiated again for a paired wireless sensor.
| Unpair a wireless sensor
A paired wireless sensor can be removed from the SmartNode by deleting it from its assigned wireless sensor slot.
To remove a paired wireless sensor:
- Open Installer Options and select Wireless Sensors.
- Select the required paired wireless sensor, then select DELETE
