Anyone succeeded installing ZWAVE-JS-UI on a Homeseer Z-net device (RPI 3 with a hat EZZee board)

I have been able to build an RPI with Zwave-JS-UI running on it and if I connect a Nortek stick everything works perfectly, when I remove the Nortek and install the HAT Ezzee board then Zwave-JS-UI does not see the ezzee zwave card. I installed ZWAVE-JS-UI with the snapd method but when I try to connect the serial-port to the plug zwave-js-ui with the sudo snap interface serial-port there are no slot showing.

I guess my question is what special configuration do I need to do to have the Ezzee board made available to the ZWAVE-JS-UI ? Do I need to change anything in config.txt ?

Thanks for any help
