WS15Z-1 Switch not showing up as binary_sensor

I am able to use this WS15Z-1 switch to turn on/off the light it is attached to.

I am not able to get a trigger or a status reading of the switch, if someone presses the on/off (top/bottom) positions.

Looking at the zwcfg file, I can see the SWITCH_BINARY section.

                    <CommandClass id="37" name="COMMAND_CLASS_SWITCH_BINARY" version="1" request_flags="4" innif="true">
                            <Instance index="1" />
                            <Value type="bool" genre="user" instance="1" index="0" label="Switch" units="" read_only="false" write_only="false" verify_changes="false" poll_intensity="0" min="0" max="0" value="True" />
                    </CommandClass>

Any suggestions?
