Pros and cons

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.

What to know before buying

Listing details to confirm

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.
