The Gen 2 Red Series On/Off Switch (LZW30-SN) is a discontinued Z-Wave 500 series in-wall relay switch with an RGB notification LED bar, multi-tap scene control and energy reporting. Z-Wave JS still drives it locally.
Events and automation triggers
Presses on this device reach Home Assistant as device triggers through
the
Z-Wave
integration, which you pick in the automation editor after pairing.
The button list, and whether each button also becomes an
event
entity, comes from what the device reports at pairing time, so it
appears once the device is on the network.
Read from Home Assistant 2026.8.3: the integration declares these trigger types, and core holds no per-model button list for this device.

Movie Mode
Installs a Home Assistant automation that dims the lights when the TV starts playing and brings them back when it stops. Add shades to close, a soundbar to power on, a scene button to trigger it by hand, and dimmable accent lights.
Solar Surplus EV Charging
Installs a Home Assistant automation that starts your EV charger when your solar array is producing a surplus and stops it when production drops, so the car pulls from the roof rather than the grid. Add a grid meter and a home battery and it holds back until they are happy too.
