Best for

Anyone who already has or is going to buy the SONOFF Zigbee Bridge hub and wants to add motion + light detection to automate when a light or device turns on.

  • Zigbee
  • Light sensor
  • Requires SONOFF hub

What is it and what's it for?

It's a sensor that detects when someone moves in a room and, unlike a basic motion sensor, also measures how much light is in the room — so you can build an automation that only turns on the light if there's motion AND it's dark, without it triggering pointlessly during the day.

Real-world use cases

At home

You install it in the hallway or bathroom, and schedule the light (connected to a SONOFF switch in this ranking) to turn on by itself only if there's motion and it's nighttime, saving on leaving it on during the day.

In a business or workshop

A store can automate a storage room or employee bathroom light to turn on by itself only when someone's there and it's dark, avoiding it staying on unnecessarily all day.

How to avoid buying the wrong one

  • Needs the SONOFF Zigbee Bridge (sold separately) — this sensor doesn't work standalone or with direct WiFi.
  • If you already have the SONOFF MINI-D switch in this ranking (or plan to add it), this sensor integrates into the same hub with no extra ecosystem added.
  • Adds a light sensor besides motion — the differentiator over a basic motion sensor that only detects presence.

The investment takeaway

It's a cheap add-on ($16.50) for anyone who's already invested in the SONOFF/Zigbee ecosystem — combined with a dry-contact switch from this ranking, it builds a motion-based lighting automation without paying for another brand's closed system.

#1SONOFF WiFi MINI-D Smart Switch — Dry Contact, Matter Compatible

SONOFF WiFi MINI-D Smart Switch — Dry Contact, Matter Compatible

MatterDry contactAC/DC
4.7 · 957 reviews

Has a dry-contact output, not a plug-and-play outlet — it installs inside a box or panel to switch an external load, which makes it more versatile for retrofitting existing wiring than a traditional smart plug. Supports Matter, so in theory it works with any compatible hub (Apple Home, Google Home, Alexa) without relying solely on the Tuya/eWeLink app. Accepts AC or DC input, useful if your project already runs on 12V/24V DC.

#2GHome Dual Smart Plug 15A — WiFi Double Outlet

GHome Dual Smart Plug 15A — WiFi Double Outlet

WiFi 2.4GHzTuya15A
4.5 · 750 reviews

It's a ready-to-use outlet (not a module for a panel), meant for anyone who wants immediate results without wiring anything. It runs on the closed GHome/Tuya ecosystem — no dry-contact output or native Home Assistant integration without an extra bridge. A good choice if simplicity is your priority, not if you're looking to integrate it into your own Node-RED project.

#3Smart Plug with Energy Monitoring 15A (4-pack)

Smart Plug with Energy Monitoring 15A (4-pack)

Consumption monitoringTuya4-pack
4.3 · 170 reviews

Real-time power monitoring (watts) is the differentiator over a simple plug — useful for consumption-based automations, like turning off a device when a cycle finishes. It's made by AiSeek: a real 1800W/15A rating with built-in short-circuit and overload protection, ETL and FCC certified, but 2.4GHz WiFi only (no 5GHz). The 4-pack makes it convenient to equip several points at once, but you're still dependent on the SmartLife app (Tuya-based) to configure them — and it doesn't pair directly with Alexa: you first connect it to SmartLife and link it from there as a third-party service to Alexa or Google Assistant.
