Quick verdict
The ZEN16 packs three independent dry contact relays into one Z-Wave module. It is the Swiss army knife for DIY automation: garage doors, fireplaces, sprinklers, motorized shades. Wiring takes some know-how, but the flexibility is hard to beat at this price.

Why it stands out
three independent dry contact relays in one compact module, making it extremely versatile
can control garage doors, fireplaces, sprinklers, or any 12-240 V load within its 15 A / 15 A / 20 A relay ratings
each relay is independently addressable in Home Assistant via Z-Wave JS
Reasons to hesitate
wiring three relays takes patience and is not a beginner project
no built-in enclosure for wall mounting, you need to plan where to put it
needs an external power supply (USB-C or 12-24V), so you must plan power as well as wiring
Best for
DIY home automation projects needing multiple independent relay controls
garage door openers, motorized shades, or fireplace switches controlled via Z-Wave
Avoid if
you want a simple plug-and-play device, since this requires wiring knowledge
you have a low-voltage-only application and cannot supply the required 12-24V or USB-C power
Privacy and local-control notes
Pure Z-Wave device with no cloud involvement. All control stays local on your Z-Wave network.
Home Assistant support: supported · integration path: Z-Wave JS.
