Zooz ZEN04 800LR Smart Plug

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 a straightforward add to the network.

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

Compatibility snapshot

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 acts as a mesh repeater for your network
• 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: Good value in Z-Wave homes, but not sensible if you would need to add a controller just for one plug.
