Device Roles

An air quality sensor monitors pollutants such as TVOC, CO2, or particulates. It lets automations ventilate a home and alert occupants before air quality affects comfort or health.

A button is a wireless controller that sends single, double, and long-press events. It triggers scenes and automations without wiring, and it is the simplest way to give people manual control.

A contact sensor is a small two-piece magnet-and-reed device that reports whether two surfaces are touching. Doors, windows, drawers, and cabinets are the typical targets.

A control panel is a wall-mounted touchscreen that runs dashboards and scenes from a fixed spot. It gives a room a permanent, app-free way to see and control the home.

A curtain controller motorizes existing curtains, blinds, or shades. It opens and closes window coverings on schedule, by sunlight, or by presence, with no rewiring of the home.

A dimmer controls both the on/off state and the brightness of a connected light. It brings smooth, scheduled, and scene-based lighting control to fixtures that would otherwise only switch fully on or off.

A door sensor reports when a door or window opens and closes. Selora AI uses door sensors for entry alerts, security arming, and energy savings when openings stay open too long.

An energy monitor measures voltage, current, and power on a circuit or whole panel and reports it to Home Assistant. It turns raw consumption into data you can automate on, bill against, and spot problems with.

A gas detector senses combustible or toxic gas such as natural gas or LPG and raises an alarm. It lets automations cut the supply, ventilate, and alert occupants before a leak becomes dangerous.

A humidity sensor reports relative humidity so automations can manage moisture, comfort, and condensation. It pairs naturally with temperature for accurate comfort recipes.

An illuminance sensor measures ambient light level, typically in lux. Selora AI uses it to decide when artificial light is needed and to adjust shades and lighting through the day.

An indoor siren is a loud audible alert device used inside the home for security warnings, severe weather alerts, and life safety events. Many models also include a strobe.

A smart light is a bulb, LED strip, or controller that switches, dims, and often changes color or temperature on command. It is the most visible and most used part of a smart home.

A smart bulb screws into a standard socket and adds dimming, color, and scheduling to any lamp or fixture. It is the fastest way to make existing lighting smart without rewiring.

A smart light fixture or lamp is a self-contained luminaire - a lamp, light bar, panel, or downlight - with built-in smart control. It brings designed, controllable light to a space without separate bulbs.

A smart LED strip, or a controller that drives one, delivers flexible accent and cove lighting with dimming and color. It reaches places a bulb or fixture cannot.

A motion sensor detects movement through passive infrared (PIR) or microwave radar. It reports motion events and is the most common building block for occupancy automations.

A presence sensor detects both motion and stillness using radar or mmWave, so it knows you are in a room even when you are not moving. Often supports configurable zones.

A relay is a wired switching module that fits behind an existing switch or fixture and turns a circuit on or off on command. It adds smart control to lights and appliances without changing the wall switch.

A remote is a multi-button wireless controller that sends press, hold, and scroll events. It drives lights, scenes, and media from the hand without wiring, giving people direct control over a room.

A smart plug switches any plugged-in device on or off and often reports energy use. It is the fastest way to automate a lamp, fan, or appliance without rewiring.

A smoke detector senses smoke and fire and raises an alarm. Connected to Home Assistant, it can trigger whole-home alerts, unlock escape routes, and notify occupants and installers instantly.

A temperature sensor reports ambient temperature so automations can react to heat and cold. It is the foundation of comfort, HVAC, and freeze-protection recipes.

A thermostat or smart radiator valve controls heating and cooling to a target temperature. It keeps rooms comfortable on a schedule while trimming the energy spent on empty or overheated spaces.

A tilt sensor reports its orientation, typically used to detect whether a garage door, gate, or hatch is open, closed, or partially open.

A vibration sensor detects movement, tilt, and shock through an accelerometer. It reports knocks, drops, and disturbances that motion and contact sensors miss.

A water leak sensor detects standing water through exposed contacts or a remote probe. It reports leaks the moment they start, so automations can shut off valves and alert the homeowner before damage spreads.
