I have an existing HA setup on a RPi 4. I have Zigbee ZHA running on a ConBee II. I am trying to add a Zooz ST2 700 series USB dongle for z-wave. It won’t auto detect it. When I try to add the integration through Settings->Devices & Services->Add Integration I get “Unknown Error Occurred” when I press submit.
