## Before you buy

- HomeBase is required. Confirm that your existing HomeBase is compatible before buying. The listing does not identify compatible HomeBase models or describe alarm behaviour, power source or installation method. IP65 is a listing claim, not independent verification.

## A good fit for

- Households seeking a eufy smoke sensor with app control and already using a compatible HomeBase.
- Buyers who want the listed IP65 rating when comparing sensor options.

## Less suited to

- Buyers who need a standalone sensor without HomeBase.
- Buyers who need confirmed model-by-model HomeBase compatibility, power details or alarm specifications before purchase.

## Customer feedback

Aggregate ratings lean positive, with most ratings in the five-star category, but the rating distribution alone does not establish why customers were satisfied or whether the sensor suits a particular HomeBase setup. Treat this as a limited signal and prioritise the stated HomeBase requirement and unprovided compatibility details.

## Frequently asked questions

### Does the eufy Security T90S0 work without a HomeBase?
The listing says HomeBase is required, so it is not presented as a standalone sensor. Check compatibility with your HomeBase before buying.
### What protection rating is listed?
The product title specifies IP65. This is a listing claim and does not establish suitability for every installation environment.
### Can it be controlled through an app?
App control is stated in the listing. It does not provide further details about notifications or alarm behaviour.
