It is the more affordable of the pair, runs about 3 years on a CR2477, covers a 110 degree arc, and adds a basic light reading plus Alexa, Google Home, SmartThings and Home Assistant, with Apple Home and Matter listed only when a SONOFF hub is used. The Eufy Motion Sensor draws the stronger owner reception and is rated for a longer 9 m, 100 degree reach, with adjustable sensitivity inside a eufy HomeBase system and Home Assistant, and without Alexa, Google, Apple Home or Matter.

What the differences mean

Which hub it needs

The Eufy Motion Sensor does nothing until a eufy HomeBase is on the network, and that base is also the only siren. The Sonoff SNZB-03P ZigBee Motion Sensor needs a Zigbee hub instead, and owners pair it with SONOFF, SmartThings, Hubitat or Home Assistant. The sensor you buy is the one whose hub is already in the house.

Reach and angle

On the sheet, the Eufy Motion Sensor is rated to 9 m across 100 degrees and the Sonoff SNZB-03P ZigBee Motion Sensor to 6 m across 110 degrees. Eufy owners commonly see a shorter usable cone than 9 m, so the rated gap is wider than a hallway may feel. Plan either sensor for the room it can actually see, not the box figure alone.

Battery

The Sonoff SNZB-03P ZigBee Motion Sensor is rated about 3 years on a CR2477, with a low-battery alert. The Eufy Motion Sensor is rated about 2 years, and the cell type is not documented. Both are meant to be left alone, and the Sonoff is the one with the longer published figure.

Light and platforms

The Sonoff SNZB-03P ZigBee Motion Sensor adds a basic light sensor that reports only dim or bright, which is enough to hold lights off in daytime and not enough for a lux threshold. It also lists Alexa, Google, SmartThings and Home Assistant, plus Apple Home and Matter with a SONOFF hub. The Eufy Motion Sensor has no light sensor and, outside Home Assistant, stays inside eufy.

Which one to buy if

What owners say

Owners of both sensors praise a short setup and a battery they forget for a long stretch. Past that, they notice different limits. Eufy Motion Sensor owners talk about pairing to a HomeBase in minutes, triggering cameras, and even a mailbox alert, then warn that usable range sits closer to a short room than the rated distance, that the sensor itself stays silent, and that it never leaves the eufy system. Sonoff SNZB-03P ZigBee Motion Sensor owners single out a low price, near-instant triggers on several Zigbee hubs, and a light reading that only says dim or bright. Their complaints are a motion entity that can stick in Home Assistant, occasional drops off the network, and a reach that stays around the rated distance.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.

Frequently Asked Questions

Which is better overall: Eufy Motion Sensor or Sonoff SNZB-03P ZigBee Motion Sensor?

The Sonoff SNZB-03P ZigBee Motion Sensor, if a Zigbee hub is already there. It is the more affordable, with about 3 years of battery, a 110 degree arc, a basic light sensor and the wider assistant list. The Eufy Motion Sensor is the one for a eufy HomeBase, with a longer 9 m rating and adjustable sensitivity.

Is the Eufy Motion Sensor a Zigbee sensor?

No. The Eufy Motion Sensor uses a eufy HomeBase, not Zigbee, Z-Wave or Thread, and it does not support Alexa, Google, Apple Home or Matter. The Sonoff SNZB-03P ZigBee Motion Sensor is the Zigbee unit in this pair.

What is the biggest difference between the Eufy Motion Sensor and the Sonoff SNZB-03P ZigBee Motion Sensor?

The network they join. The Eufy Motion Sensor requires a eufy HomeBase and stays in that system plus Home Assistant. The Sonoff SNZB-03P ZigBee Motion Sensor requires a Zigbee hub and lists Alexa, Google, SmartThings and Home Assistant, with Apple Home and Matter only through a SONOFF hub.

How far do the Eufy Motion Sensor and the Sonoff SNZB-03P ZigBee Motion Sensor detect?

The Eufy Motion Sensor is rated to 9 m across 100 degrees, and the Sonoff SNZB-03P ZigBee Motion Sensor to 6 m across 110 degrees. Eufy owners often see a shorter usable range than the sheet, so place either sensor for the room rather than the maximum figure.

Who should buy the Sonoff SNZB-03P ZigBee Motion Sensor?

Anyone with a Zigbee coordinator who wants a low-cost motion sensor, a long CR2477 rating and a simple dim-or-bright light reading for automations.

Who should buy the Eufy Motion Sensor?

Homes already using a eufy HomeBase that want motion alerts and camera triggers, and that do not need Alexa, Google, Apple Home or Matter on the sensor itself.
