Is something like the attached link an alternative Z-wave solution that could be plugged into my EISY?

Not sure about that dongle but I used the Zooz Z-Wave dongle on Polisy until finally purchasing the UDI ZMatter dongle.

From the wiki:

Z-Wave

Our Original Z-Wave implementation is the certified version of Z-Wave on the ISY-994. This code was ported to Eisy / Polisy, but is being deprecated in favor of our new more functional implementation called ZMatter Z-Wave.

The original implementation on Eisy / Polisy can use generic Z-Wave controllers such as the Zooz stick, or, it can use the ZMatter Z-Wave controller (either board or USB dongle).

The ZMatter Z-Wave implementation can only use the ZMatter Z-Wave controller (either board or USB dong
