What to know before buying

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.

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.
