In OH there is both a Shelly binding and a zwave binding. I don’t know if the devices you have support both protocols. As to the OH Zwave I checked in the OpenSmartHouse - this is what the OH Zwave binding uses) and your devices are missing, although it might mean just adding the type:ID as there are devices that look close. here and here.
Lastly OH can be used with Z-wave-js (the other references, but it [requires a few more steps])(Zwave-JS-UI in place of OH Zwave binding). Since Zwave-js is used by the bigger HA community the DB of devices tends to be bigger.
