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