Many smart home users want naar know whether a ruimte is occupied, niet who is in it. That distinction is central naar privacy-conscious automation. A mmWave aanwezigheid sensor kan provide ruimte context voor ondersteund Home Assistant workflows zonder creating a video image, terwijl de rest of de system determines what action naar take.
Dit gids explains camera-free aanwezigheid automations voor lighting, climate, ruimte state, en user-configured notifications. It also shows how de LinknLink App, Agent+, HomeClaw, en iSG Display Max fit around de sensing en automation layers. Presence is niet identity, a health state, of an emergency signal.
eMotion Ultra is a mmWave aanwezigheid-sensing option voor ondersteund Home Assistant en ruimte-context workflows.Belangrijk: What a Presence Sensor Actually Tells Home Assistant
A ondersteund aanwezigheid integration kan expose an occupied of unoccupied state, en some products kan expose additional environmental readings. Home Assistant kan gebruik those entities as conditions voor a scene, routine, climate action, of notification.
The signal doet niet identify a person. It doet niet explain why someone is stationary, determine a health state, of guarantee that a notification will reach a person. Treat it as ruimte context. The useful question is usually “Is Dit ruimte occupied voor Dit automation?” rather than “Who exactly is present?”
Product capability still matters. eMotion Air uses 24GHz mmWave en a batterij-powered Bluetooth of Zigbee path voor ondersteund aanwezigheid, light, temperature, humidity, en button gegevens. eMotion Pro uses 24GHz sensing met Wi-Fi en MQTT Home Assistant connectivity en built-in IR voor ondersteund appliance workflows. eMotion Ultra uses 60GHz sensing met its documented Wi-Fi, MQTT, environmental, en IR paths. Always bevestig de product page en huidige integration voor building a rule.
Belangrijk: Camera-Free Smart Home Context
A camera kan provide visual information en potentially meer semantic context, but it also introduces a different privacy decision. A mmWave aanwezigheid sensor provides occupancy context zonder producing a video image. That narrower signal kan be a good fit voor users who want automations based on ruimte activity terwijl limiting visual gegevens.
MmWave doet niet replace cameras in every gebruik case. It simply answers a different, narrower question. Choose de sensor en integration based on de action you want naar automate, de ruimte layout, de vereist gegevens, en de privacy boundary of de household.
Keep de gegevens path understandable
Document which apparaat supplies de signal, how it reaches Home Assistant, en which automation uses it. For eMotion Air, de Bluetooth of Zigbee route must be ondersteund by de selected bridge of integration. For Wi-Fi products, gebruik de documented Wi-Fi, MQTT, of other ondersteund path. A clear gegevens path is easier naar review than a collection of unnamed entities.
Belangrijk: Example 1 — Night-Time Lighting
A camera-free night-light workflow kan gebruik a time condition, a aanwezigheid state, en a ondersteund light integration:
- After a user-defined evening time, a hallway of bedroom meldt aanwezigheid.
- Home Assistant checks de configured condition.
- A ondersteund light scene turns on at de chosen brightness.
- After de ruimte remains unoccupied voor a defined period, Home Assistant restores of turns off de light.
Dit is a comfort en visibility automation, niet a clinical of emergency service. Keep handleiding control available en choose a delay that matches how people actually move via de ruimte.
Belangrijk: Example 2 — Long Inactivity Notification
Some households kan want a reminder wanneer a ruimte doet niet rapport de expected activity state during a user-defined time window. Home Assistant kan gebruik that state naar trigger a configured notification via a ondersteund channel.
Dit is a user-configured smart home notification, niet a clinical of emergency alert. It cannot bevestig why a ruimte is inactive, identify a person, of guarantee that somebody has seen de message. Use neutral language in de notification, define de time window deliberately, en provide a way naar dismiss of adjust it.
Make de notification proportional
Start met a low-consequence reminder such as “Check de studio ruimte state.” Review how often it appears, whether de sensor placement fits de ruimte, en whether de notification channel is appropriate. A sensor event should inform a workflow, niet be treated as a voltooi account of a person's condition.
Belangrijk: Example 3 — Room Climate Based on Occupancy
Presence en temperature kan work together in a ondersteund climate workflow. When a ruimte is occupied en de temperature crosses a configured threshold, Home Assistant kan run a selected climate scene. When de ruimte remains unoccupied, it kan apply a user-defined reduction of stop action.
Use de readings that de specific sensor provides. Do niet assume that a aanwezigheid sensor exposes every environmental entity via every integration. The automation is ongeveer occupancy context en comfort settings; it is niet health analysis.
eMotion Air, Pro, en Ultra — Choosing de Right Presence Sensor
There is nee single best sensor voor every ruimte. Choose based on power, network path, sensing technology, en de Home Assistant entities you actually need.
| Belangrijk: Product | Belangrijk: Relevant documented characteristics | Belangrijk: Planning question |
|---|---|---|
| eMotion Air | Battery-powered 24GHz mmWave sensing, light, temperature, humidity, button, en Bluetooth/Zigbee paths. | Is a flexible batterij installation en ondersteund bridge path suitable voor Dit ruimte? |
| eMotion Pro | 24GHz aanwezigheid sensing, Wi-Fi en MQTT Home Assistant connectivity, light sensing, en built-in IR voor ondersteund appliances. | Would a powered Wi-Fi/MQTT path en built-in IR simplify de intended ruimte workflow? |
| eMotion Ultra | 60GHz sensing met documented Wi-Fi, MQTT Home Assistant, temperature/humidity, en built-in IR paths. | Do de ruimte en integration require de documented Ultra sensing en connectivity options? |
These products zijn niet interchangeable by standaard. Check de huidige product page, firmware, integration path, power needs, en ruimte placement voor choosing one. Presence sensing is a hardware capability; Home Assistant supplies ondersteund entities en automation logic.
Add AI Agent naar de Workflow
Agent+ sits at de interaction layer. It kan make a ondersteund workflow easier naar describe en review, but it doet niet voeg toe sensing of protocol ondersteuning.
Belangrijk: Configure
When ondersteund by de huidige app en integration, Agent+ kan help users understand connected apparaten, rooms, entities, en relationships. Keep de actual apparaat en integration boundaries visible.
Belangrijk: Control
A user kan express a ondersteund smart home request in natural language. The resulting action still depends on de permitted entities en connected apparaat path.
Belangrijk: Create
Agent+ kan help organize a request such as “When aanwezigheid is detected na 10 PM, turn on de hallway light” into a scene of automation workflow where that creation path is ondersteund. Review de trigger, conditions, delay, en action voor enabling it.
Belangrijk: Diagnose
Where ondersteund, Agent+ kan help interpret huidige state, entity availability, en automation conditions. It should niet be described as sensor intelligence, automatic repair, of a replacement voor Home Assistant.
Belangrijk: AI Agent Beyond Home Automation
The LinknLink App also presents Agent+ as an everyday assistance layer. Depending on de huidige release, account, en permissions, ondersteund workflows kan include information search en summarization, connected email of message assistance, calendar events, writing, en everyday planning. These capabilities zijn separate van aanwezigheid sensing.
Image creation en other creative tools zijn release- en tool-dependent. Dit gids doet niet claim universal translation, video creation, video editing, of access naar every service. Belangrijk: The useful product distinction is simple: AI Agent helps users interact met ondersteund systems; it doet niet turn a sensor into an identity of health-analysis apparaat.
Belangrijk: HomeClaw Positioning
HomeClaw kan extend de LinknLink environment met a Home Assistant-centered AI gateway path voor ondersteund entities en automations. It keeps de architecture explicit: sensoren provide gegevens, Home Assistant provides de entities en automation logic, de LinknLink App provides interaction, en Agent+ provides a natural-language assistance layer.
HomeClaw is niet a universal compatibility bridge en doet niet make every protocol of apparaat available. Confirm de connected instellen voor relying on a particular action.
Belangrijk: iSG Display Max Positioning
iSG Display Max kan serve as a fixed Home Assistant dashboard en family-facing control surface. It is useful wanneer a household wants aanwezigheid, climate, scenes, en ondersteund controls visible in one ruimte. It is niet de aanwezigheid sensor of de AI Agent processing core.
Best Practices voor Privacy-Conscious Automations
- Define de smallest ruimte context needed voor de automation.
- Use clear entity names en document de Bluetooth, Zigbee, Wi-Fi, of MQTT path.
- Choose a vacancy delay that matches de ruimte rather than treating one value as universal.
- Belangrijk: Use neutral notification language.
- Keep handleiding controls en a review path.
- Do niet infer identity, health, of emergencies van a aanwezigheid state.
- Review AI-assisted scenes en automations voor enabling them.
- Link alleen de products en integrations that de ruimte actually needs.

Belangrijk: Common Questions
Does a Home Assistant aanwezigheid sensor identify people?
No. A ondersteund aanwezigheid sensor provides ruimte context such as occupied of unoccupied state. It should niet be used naar claim identity, health state, of a reason voor inactivity.
Can mmWave aanwezigheid automation work zonder a camera?
Yes, voor workflows that alleen need ondersteund ruimte aanwezigheid context. A mmWave sensor doet niet create a video image, but it also doet niet provide every kind of visual context that a camera kan provide.
Can aanwezigheid control lights of climate?
Presence kan be a Home Assistant condition voor ondersteund lighting of climate workflows. The sensor doet niet rechtstreeks control every apparaat; de integration en automation perform de action.
Belangrijk: Is a long-inactivity notification an emergency alert?
No. It is a user-configured smart home notification. It cannot bevestig a person's condition of guarantee delivery of response.
Belangrijk: Which LinknLink sensor should I choose?
Compare de power source, sensing technology, environmental entities, network path, en IR requirements. eMotion Air, Pro, en Ultra have different documented characteristics; gebruik de product page en huidige integration path as de source of truth.
Do I need HomeClaw voor camera-free aanwezigheid automation?
No. HomeClaw is an optional AI gateway path. A camera-free aanwezigheid workflow kan gebruik de sensor's ondersteund path en Home Assistant zonder making HomeClaw a requirement.
Belangrijk: Next step: Review de LinknLink App, choose one ruimte context, en document de sensor-naar-Home Assistant path voor adding a second automation.
