Wialon supports all hardware integrated with flespi. You can see those devices marked (flespi) when choosing a device type in Wialon unit settings.
Wialon automatically synchronizes with flespi and reflects the list of supported devices and their commands. All device types should be set up in the following way: create a unit in Wialon with appropriate device type marked (flespi) and set up a stream from flespi to the IP and port defined in your Wialon unit settings.
