Quick verdict
The ZEN30 solves a real problem: you have one gang box controlling a light and a fan (or two lights), and you want independent smart control of both. The top is a dimmer, the bottom is an on/off relay. Both show up separately in Home Assistant. Practical and space-efficient.
Standout: Dimmer plus on/off relay in one gang box. Control a light and fan independently without taking up two switch spots.

Local control facts
Home Assistant: zwave_js integration, Local Push (home-assistant.io, checked Oct 10, 2026)

Why it stands out
dimmer and on/off relay in a single gang, replacing a two-function combo without rewiring
both loads are independently controllable in Home Assistant
multi-tap scene support on both buttons for automation triggers
Reasons to hesitate
needs a neutral wire, so older homes without one are out of luck
fitting two functions into one gang means a deeper box, so check your box depth
Z-Wave only, with no fallback to Wi-Fi or Zigbee
Best for
bathrooms or kitchens where a fan and light share one gang box
any room where you want independent dimmer + relay control in a single switch plate
Avoid if
your gang box is shallow, since the double switch is deeper than a standard switch
you only need a single function in that box
Privacy and local-control notes
Fully local Z-Wave device. No cloud, no app account, no data leaving your network.
Home Assistant support: supported · integration path: Z-Wave JS.
Buying reality check
Price notes: Costs more than a single switch but replaces two devices in one gang. Good value if you actually need both functions.
