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

A camera provides a live video stream and motion or object detection events to Home Assistant. Every camera and video doorbell in the Selora catalog carries this role, so recipes that need a camera match any of them.

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

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.

A video doorbell combines a camera with a press event Home Assistant can use as an automation trigger. Doorbells in the Selora catalog also carry the camera role, so they work anywhere a recipe needs a camera.

An energy gateway is the metering and communications hub of a solar or storage system, the device Home Assistant actually talks to. It aggregates inverters, batteries, and meters into one local data source.

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.

An EV charger (EVSE) delivers Level 2 charging to an electric vehicle and reports sessions to Home Assistant. Under local control it becomes a schedulable, meterable load: start, stop, and current limits with no cloud in the loop.

A fan controller sets the speed of a ceiling or exhaust fan from the wall or an automation. Purpose-built fan control changes speed safely where an ordinary light dimmer would damage the motor.

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 home battery stores solar or off-peak energy and reports state of charge and power flow to Home Assistant. Local integration lets automations manage backup reserves, time-of-use arbitrage, and outage response.

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

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 light switch gives on/off control of a hard-wired lighting circuit from the wall. It replaces a standard switch and adds scheduling, scenes, and remote control while keeping the familiar paddle.

A smart lock secures a door and reports its state to Home Assistant. Selora AI uses locks for arrival and departure routines, auto-locking at night, jam alerts, and guest access with per-user codes.

A media controller sends playback commands (play, pause, skip, and volume) to media players from a physical control. It gives a room hands-on control of music or video without an app.

A media player is any device Home Assistant controls through a media_player entity: a TV, streaming box, or stick. It reports playback state and accepts power, volume, source, and app commands, all over the local network.

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.

An occupancy sensor reports whether a space is in use, typically from passive infrared (PIR) motion. It turns lights and scenes on when someone enters and off after the room is empty.

An outdoor smart light is a weather-rated fixture, spot, or strip for gardens, paths, and facades. It adds dimming, color, and schedules to exterior lighting, often tied to sunset and presence.

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 scene controller sends multi-tap and hold events that trigger scenes and automations beyond the load it switches. A single keypad or switch can drive many actions across the whole home.

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 solar inverter converts DC power from panels into AC power for the home and reports production to Home Assistant. Read locally, it feeds the energy dashboard and drives automations that react to real-time solar output.

A streaming player is a dedicated box or stick Home Assistant drives locally: playback, app launching, and remote-style navigation for whatever TV it is plugged into.

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 TV in this role is a television Home Assistant controls locally as a media player and remote: power, volume, input source, and app launch with no cloud round trip.

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.
