Error: ‘Node not found’ when reading Z-Wave door sensor status on SiFive HiFive Unmatched

hey guys am developing a home automation controller using a `SiFive HiFive Unmatched` with Embedded Linux. The controller should read data from a `Z-Wave door sensor`, I am using a Z-Wave USB Stick (Model: AEOTEC Z-Stick Gen5, Version: 1.1). i have verified the Z-Wave network configuration and device inclusion, checked the door sensor status and connection, checked that the OpenZWave library is correctly installed and configured.

But am getting the error

`Error reading door status: Node not found`.

here is my code

import openzwave

zwave_network = openzwave.network.ZWaveNetwork(openzwave.options.ZWaveOption("/dev/ttyUSB0"))
zwave_network.start()

try:
    door_sensor = zwave_network.nodes[1]
    door_status = door_sensor.get_sensor_binary_value()
    print(f"Door Status: {door_status}")
except Exception as e:
    print(f"Error reading door status: {e}")
finally:
    zwave_network.stop()
