Zooz ZEN04 800LR Smart Plug - Clean Z-Wave local control without the usual vendor-cloud baggage

Quick verdict

The ZEN04 is a Z-Wave smart plug that does exactly what you'd expect - reliable local switching with solid HA integration. No cloud nonsense, no app account required. You need a Z-Wave controller, but if you already have one, this is an easy add to the network.

Standout: Clean Z-Wave local control without the usual vendor-cloud baggage.

Local control facts

Home Assistant: zwave_js integration, Local Push (home-assistant.io, checked Sep 10, 2026)
Z-Wave JS: in the device database, listed as Zooz ZEN04 (Indoor Smart Plug) (github.com, checked Sep 10, 2026)

Why it stands out

native Z-Wave JS integration in Home Assistant with full local control and no cloud account
Z-Wave 800LR chip provides excellent range, and repeats for the mesh when included as a mesh device (a plug included as a Z-Wave Long Range device does not repeat)
reports live wattage, current, voltage and kWh to the hub, so it doubles as an energy meter
no vendor cloud or app account needed - all control stays on your local Z-Wave controller

Reasons to hesitate

no Apple Home, Google Home, or Alexa support - Z-Wave only talks to a Z-Wave controller
requires a Z-Wave USB controller or hub to function at all
less appealing if your home is mostly Zigbee or Wi-Fi - adding Z-Wave just for a plug is overkill

Best for

Home Assistant households with Z-Wave already in the stack
buyers who care more about clean local control than app polish

Avoid if

you want native voice-assistant ecosystem support
you do not have or want Z-Wave infrastructure

Privacy and local-control notes

One of the cleaner examples of a local-first smart plug if your house already revolves around Z-Wave and Home Assistant rather than consumer voice-assistant ecosystems.

Home Assistant support: supported · integration path: native Z-Wave.

Buying reality check

Price notes: Around $20 new at The Smartest House on 2026-09-07 (a sale price against a $35.95 list), with open-box and refurbished units listed but out of stock. It was about $28 in late August, so the price moves; check before you buy a handful.

What changed for this product

Sep 7, 2026 · Corrected

Shelly follow-up audit and 16 more corrections

Six more Shelly products went through the same source check as the rest of the catalog. The Plus i4’s inputs are mains-level, not dry-contact (the DC model is the low-voltage one). The BLU Motion, BLU Button1 and BLU Door/Window pages no longer say a Shelly gateway is required: a Bluetooth adapter on the Home Assistant host or any Bluetooth proxy hears them directly. The Wall Display XL mounts to a standard switch box, and its dashboard claim now says exactly what Shelly ships: a Home Assistant page that loads a dashboard URL, deprecated and then restored in firmware 2.7.0. Five manufacturer links that had gone dead were replaced, the ZEN04 price was refreshed, the Tedee GO page names the official tedee integration as its non-Thread local path, and the G6 Instant page notes its IPX5 rating.
