Enable NodOn Z-Wave 4 button wall switch (CWS-3-1-01) in Home Assistant
Raw
nodon_ha.md

Home assistant doesn't properly support Central Scene events currently. This is how to make it recognize those events.

  1. Stop home assistant (From the UI, otherwise it might restart automatically).
  2. In zwcfg_0x*xml file in configuration folder, in block for NodOn switch (search for name="NodOn"), replace <CommandClass id="91" name="COMMAND_CLASS_CENTRAL_SCENE"... block with:
            <CommandClass id="91" name="COMMAND_CLASS_CENTRAL_SCENE" version="1" request_flags="4" innif="true" scenecount="4">
                <Instance index="1" />
                <Value type="int" genre="system" instance="1" index="0" label="Scene Count" units="" read_only="true" write_only="false" verify_changes="false" poll_intensity="0" min="-2147483648" max="2147483647" value="4" />
                <Value type="int" genre="user" instance="1" index="1" label="Button 1" units="" read_only="false" write_only="false" verify_changes="false" poll_intensity="0" min="-2147483648" max="2147483647" value="0" />
                <Value type="int" genre="user" instance="1" index="2" label="Button 2" units="" read_only="false" write_only="false" verify_changes="false" poll_intensity="0" min="-2147483648" max="2147483647" value="0" />
                <Value type="int" genre="user" instance="1" index="3" label="Button 3" units="" read_only="false" write_only="false" verify_changes="false" poll_intensity="0" min="-2147483648" max="2147483647" value="0" />
                <Value type="int" genre="user" instance="1" index="4" label="Button 4" units="" read_only="false" write_only="false" verify_changes="false" poll_intensity="0" min="-2147483648" max="2147483647" value="0" />
            </CommandClass>
