Air Flow and Temperature USB Sensor Port Behavior

The Air Flow and Temperature USB sensor (with chipset FTDI) does not get automatically detected when connected to the USB port. You need to set up the USB port in the Managed Devices page as a usb_sensor type before connecting the sensor. Once this initial setup is done, the sensor will then be detected as a usb_sensor. If the sensor has the default name usbSX-Y, it gets changed to the configured sensor name, for example, AirFlowTemperature. When you disconnect the sensor device, the port will be deactivated and the USB sensor device name gets reverted to default usbSX-Y from AirFlowTemperature. However, the device port type will still be recognized as usb_sensor. If you want to use the port as a usb_serial, configure it to its default setting.

CLI Command Example

Configuration command to update the USB device name.

[admin@nodegrid /]# cd /settings/devices 
[admin@nodegrid devices]# rename AirFlowTemperature
[admin@nodegrid {devices}]# set new_name=usbS0-1
[admin@nodegrid {devices}]# commit
