Pros & Cons
Aqara Smart Plug (US, ZNCZ12LM)
Pros
- +Zigbee keeps it off your Wi-Fi entirely, and it acts as a mesh repeater for Aqara sensors
- +Automations execute on the hub, so they keep running through an internet outage
- +Full 1,875W rating with hardware overload and overheat cut-off
- +Genuinely useful if you already run Aqara sensors — the plug becomes the range extender
Cons
- −The hub is mandatory and not in the box; the real entry price is the plug plus an Aqara hub
- −$29.99 for one plug makes it the second-most expensive per-outlet option here
- −Aqara publishes no motor or HP rating
- −A 2018 design; Aqara's newer Matter-era hardware has moved on and this SKU has not
- −47 mm wide body is awkward on a horizontal duplex receptacle
Emporia Energy Monitoring Smart Plug (1-Pack)
Pros
- +The metering is the product, and it slots straight into Emporia's whole-home energy dashboard
- +$11.99 single or $34.99 for four direct from Emporia — the cheapest per-plug metering in the category
- +Emporia is unusually honest about its limits, publishing a continuous rating and a do-not-use list
Cons
- −10A continuous, not 15A — the 15A figure is a peak good for one hour a day, so the real ceiling is about 1,200W
- −Emporia's own store tells you not to plug in a fridge, freezer, pump, heat lamp or router
- −Roughly 80,000 North America Smart Plugs sold July 2022 to May 2023 were recalled by CPSC in September 2023 for inadequate grounding (electric shock hazard); check what you receive
- −Alexa and Google only — no HomeKit, no Matter, no local control, no Home Assistant path
- −Emporia publishes no dimensions, so you cannot tell in advance whether it blocks the second socket
