Aqara Smart Plug

Quick verdict

The US Aqara Smart Plug (model ZNCZ12LM) is a solid, fully local Zigbee plug: 1875 W / 15 A, energy monitoring, and a mains-powered Zigbee router that helps your mesh. The catch is which integration you run. Zigbee2MQTT exposes the whole metering set - power, energy, voltage, current, plus overload protection and power-outage memory. ZHA does ship a quirk for this model (zhaquirks/xiaomi/aqara/plug_maus01.py, which claims lumi.plug.maus01) and it adds the electrical-measurement and metering clusters, but a quirk only applies to units whose Zigbee signature matches it, and owners outside that signature report the power attributes coming back unavailable. Buy it for Zigbee2MQTT; if you are on ZHA and want energy data, buy something else.

Standout: Name-brand Zigbee metering plug that doubles as a router, with the full energy set exposed under Zigbee2MQTT.

Compatibility snapshot

Why it stands out

• energy and power reporting, plus voltage and current, under Zigbee2MQTT
• acts as a mains-powered Zigbee router and extends the mesh
• overload protection and power-outage memory are exposed as settings
• no Aqara hub or account needed when paired straight to your coordinator

Reasons to hesitate

• under ZHA the metering quirk only applies to matching Zigbee signatures, so power data is not guaranteed
• Aqara does not state a Zigbee 3.0 stack for this model, only “Zigbee”
• costs roughly twice what a bare-bones metering Zigbee plug does
• US model only tops out at 1875 W / 15 A, so it is not for large loads

Best for

• Zigbee2MQTT users who want per-appliance energy data from a name-brand plug
• filling in Zigbee mesh coverage where a router is needed anyway

Avoid if

• you run ZHA and are buying it specifically for energy monitoring, unless you can confirm the quirk applies to your unit
• you want the cheapest possible metering plug per outlet

Privacy and local-control notes

A plain Zigbee plug. Joined to your own coordinator it never talks to Aqara at all, and no Aqara account or hub is involved. The Aqara app and its cloud only enter the picture if you pair it to an Aqara hub instead.

Home Assistant support: supported · integration path: Zigbee2MQTT (full metering) or ZHA (on/off, with metering via the plug_maus01 quirk when the signature matches).

Buying reality check

Price notes: $29.99 at Aqara direct for the US version. Cheaper metering Zigbee plugs exist, so this one earns its price on build quality and brand support rather than on cost per outlet.
