Data from Amazon and official Aqara and Sonoff sites.

2026 verdict

Which Zigbee smart plug does more for the money?

Winner

Aqara Smart Plug (US)

$32.99

Buy on Amazon USACheck price

The Aqara Smart Plug (US) takes it, backed by a slightly higher 1875W maximum load, energy monitoring, overheat/overload protection and a broader integration list than the Sonoff Zigbee Smart Plug S40 Lite offers. Both are Zigbee-only outlets that need a hub, both act as Zigbee routers, and both share a Type B, 15A rating, so their bones are similar. The real gap is what Aqara layers on top: daily and monthly power tracking, built-in overload safety, and Apple HomeKit plus Matter through an Aqara hub, whereas the Sonoff Zigbee Smart Plug S40 Lite trades those away for a lower price and native Samsung SmartThings support. Go with the Aqara Smart Plug (US) for the fuller feature set; the Sonoff Zigbee Smart Plug S40 Lite makes sense when cost and simple mesh extension are the priority.

Frequently Asked Questions

Is the Aqara Smart Plug (US) or the Sonoff Zigbee Smart Plug S40 Lite the better buy?

The Aqara Smart Plug (US) is the more complete outlet, adding energy monitoring, overheat/overload protection, a marginally higher load rating and more integrations. The Sonoff Zigbee Smart Plug S40 Lite is the cheaper option and adds Samsung SmartThings support.

Do both plugs need a Zigbee hub?

Yes. Neither the Aqara Smart Plug (US) nor the Sonoff Zigbee Smart Plug S40 Lite has a Wi-Fi or Bluetooth radio, so both connect over Zigbee and require a compatible Zigbee hub or coordinator to function.

Which one can monitor energy usage?

Only the Aqara Smart Plug (US). It records power consumption on a daily and monthly basis, while the Sonoff Zigbee Smart Plug S40 Lite does not include energy monitoring.

How do they compare on smart-home integrations?

The Aqara Smart Plug (US) works with Apple HomeKit and Matter (via an Aqara hub) on top of Alexa, Google Home, Home Assistant and IFTTT. The Sonoff Zigbee Smart Plug S40 Lite skips HomeKit and Matter but supports Samsung SmartThings, which Aqara does not.

Who should buy the Sonoff Zigbee Smart Plug S40 Lite instead?

Buyers who already own a Zigbee hub, want the lowest price, and mainly need an outlet that also repeats the Zigbee mesh. It suits Home Assistant, Zigbee2MQTT or SmartThings users who do not need energy monitoring or Apple HomeKit.
