Smart Sensors

How Smart Sensors Work

Smart sensors detect a change, such as motion, an open door or rising humidity, then send an alert or trigger an automation. For example, a motion sensor can switch on a light, or a leak sensor can notify your phone if water is detected.

Types of Sensors and Controllers

• Motion and presence sensors: Motion sensors detect movement, while presence sensors can detect when someone is still in a room on supported models.
• Door and window sensors: Contact sensors alert you when a door or window opens and can trigger automations.
• Temperature, humidity and leak sensors: Monitor conditions at home and get alerts for leaks in areas such as laundries and kitchens.
• Buttons, cubes and switches: Wireless controls for scenes, lights and routines.
• Hubs and controllers: Smart home hubs, curtain and blind drivers, relay modules and garage door controllers.
• Alarm kits: Bundled sensors, keypads and sirens for a simple home alarm setup.

Things to Check Before You Buy

• Hub and protocol: Many battery sensors use Zigbee or Thread and need a compatible hub, such as an Aqara or SmartThings hub. Wi-Fi sensors connect directly to your router.
• Ecosystem: Check compatibility with Apple Home, Amazon Alexa, Google Home, SmartThings or Matter, as support varies by product.
• Battery: Check the battery type and expected battery life.
• Installation: Relay modules and some controllers may involve fixed electrical wiring, which must be completed by a licensed electrician in Australia.

Use sensors with smart lighting, smart locks and smart cameras, or browse the Xiaomi and eufy ranges.

Smart Sensor FAQs

Do smart sensors need a hub?

Many battery-powered sensors use Zigbee or Thread and need a compatible hub. Wi-Fi sensors can connect directly to your router. Check the product details before buying.

What is a presence sensor?

A presence sensor is designed to detect whether someone is in a room, even when they are sitting still, on supported models. This can make lighting and climate automations more reliable than motion sensing alone.

Can smart sensors work with Apple Home, Alexa or Google Home?

Many can, but support depends on the sensor, hub and platform. Check the listed compatibility for each product.

How long do sensor batteries last?

Battery life depends on the sensor, how often it reports and where it is installed. Check the stated battery type and expected life for each model.
