## Customer Reviews

### ⭐⭐⭐⭐ Works well, if your IQI is high
*by P***. on 20 August 2024*

Highly suggest a few ikea trafaldi sockets to extend zigbee network range, it will be flawless from there on. Works well when I enter home to turn on lighting

### ⭐ requires zigbee bridge to work
*by A***S on 4 November 2024*

it is very inconvenient for such a simple device to require another 150 AED device to work. why is the hub even required when there are many other door sensors that don't require a bridge/hub?don't buy this
