7 Surprisingly Useful Things You Can Do With UniFi Sensors

Most people know UniFi as the brand behind great WiFi and professional security cameras. But Ubiquiti also makes a range of compact sensors — small wireless devices that monitor things like motion, temperature, humidity, door and window openings, and water. They connect to your existing UniFi network and report back through the same app you already use.

The use cases are more practical than you might expect. Here are seven we see working well for Southern Highlands homes, farms, and businesses.

1. Know the moment someone opens a door or window

UniFi door and window sensors are magnetic contact sensors — one half on the frame, one on the door or window itself. When they separate, your phone gets a notification. This is useful in several scenarios: knowing when a child has left through a back gate, getting alerted when a vehicle shed door is opened while you're not home, or monitoring a medicine cabinet or liquor cabinet in a rental property or shared space. Simple, reliable, and runs on battery for months.

2. Monitor temperature in a wine cellar or cool room

The Southern Highlands has a surprising number of serious wine collectors, and a well-stocked cellar represents a significant investment. A UniFi temperature and humidity sensor placed in your cellar sends you an alert if the temperature drifts outside your set range — whether that's because the cooling system has failed, a door has been left open, or the power has gone out. Catch it early and you can act before any damage is done.

3. Detect a water leak before it becomes a flood

Water leak sensors sit on the floor near appliances, pipes, or in areas prone to dampness — under the kitchen sink, behind the washing machine, near the hot water system, in a basement. When water contacts the sensor, you get an immediate alert. For a weekender that's unoccupied for most of the week, catching a leak early can mean the difference between a minor repair and significant water damage.

4. Monitor humidity to protect timber floors and furnishings

The Southern Highlands climate — particularly in winter and spring — can be hard on timber floors, antique furniture, and musical instruments. A humidity sensor in the relevant room lets you track conditions over time and get alerts if humidity rises to a level that could cause warping or damage. Useful for both occupied homes and weekenders that may be sealed up for extended periods.

5. Track motion in areas that cameras don't cover

Motion sensors are a cost-effective way to add awareness to areas where a camera isn't practical or appropriate — inside a safe room, in a garage, along a corridor, or in a garden shed. They work alongside your camera system rather than replacing it: the sensor triggers an alert, and you check the nearest camera to see what's happening.

6. Get notified when the generator or pump shed is accessed

Rural Southern Highlands properties often have equipment sheds, generator rooms, or pump houses that need to be monitored for access and environmental conditions. A combination of door sensors, motion sensors, and temperature monitors in these spaces gives you visibility over assets that are typically out of sight — and out of mind until something goes wrong.

7. Keep tabs on a granny flat or separate dwelling

For properties with a separate cottage, granny flat, or staff accommodation, sensors are a tactful way to maintain a degree of awareness without being intrusive. Temperature monitoring ensures the space is liveable in winter. Door sensors on the entry confirm when the space is being accessed. Water sensors under the bathroom and kitchen catch leaks early. All of this is visible in the same app as everything else on the property.
