Hub Range & Placement
We recommend a maximum of 2 doors per hub for the most reliable performance — unless your doors are right next to each other (e.g. double patio doors). Each hub has a Bluetooth range of 5–7 metres — walls and floors reduce this. If your additional door is further away, consider a second Starter Pack, which includes its own hub for a separate zone of the house.
Customer Reviews
“I got this as I wanted confidence that my parents were locking the door each night without feeling like they were too intruded upon. They were really happy with this.”

“The kids can make getting into the car a stressful experience sometimes. Then I get onto the A1 and think ‘have I locked the door?’ Now I just stop and look at the app and I know for sure!”
