Pre-configured devices are already configured in Ginjer, and clients need to simply forward the device's data to Ginjer. Ginjer will extract the required output from the device's hex output value and convert it into a human-readable form.
For more information, refer to the pre-configured section in Ginjer Documents: https://docs.ginjer.io/#preconfigureddevices
On the other hand, non-pre-configured devices need to have all configurations set up in Ginjer to obtain the exact output by the client.
If you need any assistance to configure new device on Ginjer, kindly reach out to support@senraco.com.
