## At a glance

- Pet mode is described as reducing false alerts for pets under 80 lb \(36 kg\).
- The listing claims up to five years of battery life under normal conditions, based on internal lab testing.
- Requires a compatible HomeBase and specified minimum software versions.
- The listing describes a 90° detection angle and movement detection up to 8 m away.

## Pros

- Pet mode offers a way to reduce false alerts in homes with pets within the stated weight limit.
- The claimed 200 m open-air connection range may suit installations where the sensor is far from the HomeBase.
- Wall mounting is listed, and the instructions describe placement above 6 ft \(1.8 m\).

## Cons

- Requires a compatible HomeBase to operate, so it is not a standalone sensor.

## Before you buy

- The five-year battery life is a manufacturer claim based on internal lab testing, and actual performance may vary. Pet mode is intended for pets under 80 lb \(36 kg\), but pets jumping on furniture or close together may still trigger an alert. Avoid direct light, heat sources, windows, vents and aim toward the monitored area rather than doors or pet-accessible stairs or furniture. The listing gives recommended heights of both above 6 ft \(1.8 m\) and 6–7.5 ft \(1.8–2.3 m\). HomeBase compatibility requires specified versions: Mini v4.0.5.2 or above, HomeBase 2 v3.4.1.2 or above and released after 2021, HomeBase 3 v3.7.2.6 or above, or HomeBase Pro v4.1.4.3 or above. The title says an EU version is required, while the compatibility details list HomeBase models without specifying regional versions, so confirm regional compatibility for the selected listing.

## In the box

- Motion sensor (Included)

## A good fit for

- eufy HomeBase owners seeking a motion sensor with a pet mode.
- Buyers who can update a compatible HomeBase to the required software version.

## Less suited to

- Buyers without a compatible HomeBase or seeking a standalone motion sensor.
- Homes where pet movement must never trigger alerts, since the listing notes limitations to pet detection.

## Customer feedback

Aggregate ratings lean positive overall, but a meaningful minority are three-star or one-star. Without written feedback, the ratings do not show what customers liked or disliked. They offer limited guidance on whether the HomeBase requirement, pet detection or battery-life claims meet an individual buyer's needs.

## Frequently asked questions

### Does the eufy Motion Sensor E20 work without a HomeBase?
No. The listing says a compatible HomeBase is necessary for operation.
### Which HomeBase models are listed as compatible?
HomeBase Mini, HomeBase 2, HomeBase 3 and HomeBase Pro are listed, subject to specified minimum software versions. The title also says an EU version is required, so confirm regional compatibility.
### How far away can it detect movement?
The listing claims movement detection up to 8 m away with a 90° detection angle. Separately, it claims a stable open-air wireless connection with HomeBase up to 200 m.
### Does pet mode prevent all pet-related false alarms?
No. It is described as reducing false alerts for pets under 80 lb \(36 kg\). The listing notes that jumping on furniture or pets staying close together can still lead to an alert.
