Zooz ZEN32 Scene Controller

The ZEN32 answers a problem every smart home eventually hits: wall switches control one thing, but rooms contain many. It puts a normal relay switch plus four small programmable buttons in a single gang box, each button firing local Z-Wave scene events with a hub-controllable LED — so a guest sees a light switch, while your household gets one-tap control of the whole room. It runs entirely locally, and at around $30-48 it is one of the cheapest ways to make a smart home usable by people who never open an app.

Durability

The switch carries a 5-year warranty with lifetime tech support, and the button panel itself is a user-replaceable part sold for a few dollars — a small design decision that says a lot in this category. Long-term multi-unit households are common in community threads, and we found no recurring pattern of relay, membrane, or LED failures. The honest caveats are electrical: it needs a neutral wire, the relay is on/off only, and Zooz warns against halogen and other high-inrush loads.

Lock-in and ecosystem

Everything meaningful about this device is standard Z-Wave: the relay is a Binary Switch, the buttons emit Central Scene events, and the LEDs are configuration parameters — all exposed locally in Z-Wave JS, Hubitat, and SmartThings with no proprietary layer. Home Assistant support is mature enough that Zooz's own documentation walks through the setup, and community blueprints handle the fancy tricks like keeping each button's LED color synced to the device it controls. There is no Zooz cloud and no account to create.

Longevity

Zooz has shipped this same product across three hardware generations — the 2021 original on a 700-series chip, a Long Range revision, and the current VER 3.0 on an 800-series chip — which is a decent track record of iterating without abandoning. Firmware updates arrive over Z-Wave and files are published freely, though the record is active rather than spotless: a couple of documented bad builds caused real breakage until users rolled back or re-included. The practical rule from the community is the right one — working units don't need new firmware.

Repairability

The vendor-death test comes back clean: as a certified Z-Wave device it will keep working with any standards-compliant controller if Zooz — the house brand of US retailer The Smartest House — ever disappears, because no part of its operation touches a vendor server. Replacement button panels are sold separately for the current revision, wiring is standard in-wall switch fare, and if the smart half ever died entirely, the main button still behaves as a plain relay switch for the load.
