Smart home glossary: 20 terms explained in plain English

Quick answer: Smart home jargon boils down to a handful of ideas: what you control (loads), what controls it (panels, modules, hubs), what senses the room (sensors) and what ties it together (scenes, schedules and the app). The definitions below are the ones you will meet in a Tixa quote or any other brand’s brochure.

Control and wiring

• Load: anything that draws power and that you switch, such as a light, fan, AC, geyser or curtain motor.

• Control point: one switch position on a wall. A six-switch plate has six control points.

• Retrofit: adding smart control to existing wiring by placing a module behind the current switch, with no new cables.

• Module: the small device inside the switch box that switches or dims a load and talks to the panel and app.

• Panel: what you see on the wall. TouchX is a glass touch panel; Mosaic Pro is a modular plate.

• Neutral wire: the return wire most smart modules need. Indian switch boxes usually have one; an installer confirms.

• Dimmer: control that sets a light’s brightness or a fan’s speed rather than just on or off.

• Regulator: the fan speed knob. A smart module replaces it with app and panel control.

Sensing and security

• Motion sensor: detects movement and can switch lights or trigger an alert.

• Door sensor: two-part magnet that knows whether a door or window is open.

• Light sensor: measures ambient light so lights only come on when the room is actually dark.

• Smart lock: a door lock opened by fingerprint, PIN, RFID card, the app or a mechanical key.

• Time-limited PIN: a lock code that works only between set times, useful for help or guests.

Software

• Scene: a saved combination of states, like ‘Movie’ dimming lights and closing curtains in one tap.

• Schedule: a scene or load that runs at a set time or on set days.

• Automation: a rule that reacts to something, for example ‘if the door opens after 11pm, turn on the hallway light’.

• Hub: the small box that keeps scenes and schedules running locally so they work without the internet.

• Voice assistant: a speaker or phone assistant that can run scenes and switch loads by name.

• Sharing: giving family members their own access to the app, with or without editing rights.

• Local control: the panel still works as a physical switch even when Wi‑Fi or the app is unavailable.

Frequently asked questions

What is the difference between a scene and an automation?

A scene is something you run; an automation is something that runs itself in response to a trigger like time, motion or a door opening.

Do I need a hub?

For reliable schedules and offline operation, yes. Tixa includes one with every installation.

Key takeaways

• Loads, control points and modules describe the hardware side.

• Scenes, schedules and automations describe the behaviour side.
