Changing Z-Wave Parameters On The Fly Using HA

While not possible with any official system drivers, a workaround might be including the device in HA. HADB uses generic device drivers with limited capability. However, HA easily allows changing parameters by automation via its visual editor.

As an example, I created a virtual switch in HA that turns a ZEN04’s LED on or off in HA via two automations. Brought the virtual switch into HE. It worked.

I guess it’s an option, if somewhat convoluted, if one really wants to change Z-Wave device’s parameters programmatically.
