Sensors: the quiet part of a smart home

Plan motion and door sensing around placement, supported automation, hub requirements and the difference between sensors and cameras.

Quick answer: A sensor reports a supported condition, such as motion, presence or a door opening. A compatible routine can use that event to control a device or send an alert. The available triggers, network and records depend on the sensor and app.

Motion and presence

A passage light is a useful starting example: a compatible sensor detects activity and a supported routine switches on the light. Test placement, coverage and timeout in the actual space. Do not assume motion detection proves a room is empty, or that every sensor detects a still person.

Door sensing

A contact sensor can report open or closed state where supported. Check mounting position and alignment. Confirm whether you need a notification, a history view or an automation, because these are separate functions.

Does a sensor record video?

A motion or contact sensor is different from a camera and does not by itself provide video. However, the app may retain device states, events or activity history. Ask what the selected setup records, who can access it and which service terms apply rather than assuming “no recording” means no data.

Check the network and alerts

Selected Tixa sensor options use HomeSync and require a compatible hub. Verify the specific device and range. Push, WhatsApp and email notifications have different availability and service conditions; paid services should be confirmed separately.

Test before relying on a routine

Walk through the space, try normal household behaviour and check the intended action. Confirm power, network and battery failure behaviour. Sensor routines do not automatically contact emergency services.

Use the app guide and support tutorials for the selected model, then explore starter routines.

Plan your next step

Use the Tixa room quotation builder to list your rooms and controls. Tixa will confirm the selected models, compatibility, current prices and installation scope before an order.
