Aeotec Water Sensor 6 ZW122/binary sensor

Back in October I bought one of these.
Integration was a breeze. Upon integration it created a binary sensor. However the binary sensor wouldn’t react to any change and on restart shows as unavailable. After googling I suspect it is a parameter issue but I can’t figure out which one or what to change it to. Can anyone offer any insight please? I’m new to zwave.
