Configuring Razberry Zwave

Howdy, folks. New member, coming from OpenHAB because I found it difficult to configure and limited in options. Hoping I can get myself up and running with HASS, but I’m struck trying to configure the Razberry Zwave board.

I’ve added the necessary string to config.txt to disable BT and am able to log into the web interface, but I can’t SSH into the system to issue the other commands. I keep getting a ‘connection refused’ error. Yes, I did install SSH on the system, but still no dice.

Can someone point me in the right direction?

Thanks in advance!
