New install, max number of devices

[gcain]

I recently bought a ZME Z-Wave USB Dongle and compiled the z-way-test application.

When I try add a new device, it tells me;
> [2023-08-25 02:24:46.531] Max number of devices (1) reached

Since I am on a Raspberry Pi and just playing with it, how can I add a new device?

The USB dongle does not come with a Z-Way license like the Razberry boards do.

UZB can be used together with Z-Way software (a license might be required)

If you want to use Z-Way on a platform different from Raspberry Pi with support for Z-Wave you can download the code free of charge but you will need a Z-Wave.Me transceiver hardware such as UZB and you will need a licensing key to unlock the Z-Wave function. You can purchase the licensing code from here or from our partners and some of them may already bundle the UZB with such a license. You are allowed to change and adapt the UI and resell products based on Z-Way and UZB. No additional cost.

Thanks Ian,

I want to use the dongle on a rPi (as you mentioned in your quote), using the C API, not the Z-Way platform (I'm not sure how far the Z-Way label applies).

Do I still need a licence in this use-case?

Per the links I provided, the USB dongle requires a license to use with Z-Way. The Raspberry Pi hat does not require such license as it is included. The hat would have been a better choice if you're going to stick with a Raspberry Pi.

I am only wanting to use the C-Library, does this also require a licence?

I don't want to use the Z-WAy platform, just the C library.
