How to Choose a Window Sensor

Connectivity and Compatibility

Check if the sensor uses Z-Wave, Zigbee, or Wi-Fi to ensure it works with your existing smart hub or alarm system. Most UK homes use Z-Wave with Ring or Yale hubs.

Battery Life and Power

Look for sensors with CR123A or AAA batteries that last 12-24 months. Avoid models with short battery life to reduce maintenance.

Range and Detection

Consider the sensor range (typically 20-40m) and magnetic detection gap. Wider gaps suit larger windows or sliding doors.

Mistakes to Avoid

  • Buying a sensor incompatible with your hub.
  • Ignoring battery life and replacement costs.
  • Choosing a sensor with poor range for large homes.
