How to connect and configure wireless sensors

The GARM system supports ASTRA wireless devices — easy-to-install, wire-free sensors that enhance your security setup. This guide walks you through adding, configuring, enabling, managing, and, if needed, disabling or removing these sensors.

The GARM Link PRO hub exclusively supports ASTRA wireless devices. For a comprehensive list of compatible models, refer to the Frequently asked questions about GARM
