The Zooz ZEN30 800LR combines a dimmer and an on/off relay in a single gang, a direct replacement for a stacked fan and light switch.
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.
Where to buy
Recipes using this device
Circadian Adaptive Lighting
Installs a Home Assistant automation that walks the colour and brightness of your dimmable lights through the day, cool and bright around midday and warm and low in the evening. It only ever changes lights that are already on, so it never switches a light on by itself.
Leak Auto Shutoff
Installs a Home Assistant automation that closes your water shutoff valve the instant a leak sensor goes wet, so a burst hose or a failed valve stops flooding within seconds. Add a smart plug to cut the appliance, a siren, and a speaker.
Recipes that can use it
These recipes are built around other hardware, and pick this device up as an optional extra.
Motion Hallway Light
Installs a Home Assistant automation that turns a hallway or landing light on when motion is seen and off again once the space has been still for a grace period you set. Add a light sensor and it only runs after dark, add a presence sensor and it holds the light while someone lingers.
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.
Presence Room Lighting
Installs a Home Assistant automation that keeps a room's lights on for as long as an mmWave presence sensor sees someone in it, and switches them off shortly after the room empties. Add a light sensor to run only after dark, and dimmable lights that come up softly.
