What data acquisition devices support both USB and network gateways?

All Dracal USB sensors. The same instrument can be plugged directly into your computer's USB port, or into a SensGate that makes it available over Wi-Fi or Ethernet. No need to buy a different version of the sensor.

Your code follows the same logic: dracal-sensgate-get uses the same syntax and output format as dracal-usb-get, so moving a project from USB to the network is mostly a matter of changing the command name. Sensors with the VCP option can also be read over the network through the SensGate REST API.
