Many smart home users want a know whether a stanza è occupied, non who è in it. That distinction è central a privacy-conscious automation. A mmWave presenza sensore può provide stanza context per supportato Home Assistant workflows senza creating a video image, mentre il rest of il system determines what action a take.
Questo guida explains camera-free presenza automations per lighting, climate, stanza state, e user-configured notifications. It also shows how il LinknLink App, Agent+, HomeClaw, e iSG Display Max fit around il sensing e automation layers. Presence è non identity, a health state, o an emergency signal.
eMotion Ultra è a mmWave presenza-sensing option per supportato Home Assistant e stanza-context workflows.Importante: What a Presence Sensor Actually Tells Home Assistant
A supportato presenza integration può expose an occupied o unoccupied state, e some products può expose additional environmental readings. Home Assistant può usa those entities as conditions per a scene, routine, climate action, o notification.
The signal fa non identify a person. It fa non explain why someone è stationary, determine a health state, o guarantee that a notification will reach a person. Treat it as stanza context. The useful question è usually “Is Questo stanza occupied per Questo automation?” rather than “Who exactly è present?”
Product capability still matters. eMotion Air uses 24GHz mmWave e a batteria-powered Bluetooth o Zigbee path per supportato presenza, light, temperature, humidity, e button dati. eMotion Pro uses 24GHz sensing con Wi-Fi e MQTT Home Assistant connectivity e built-in IR per supportato appliance workflows. eMotion Ultra uses 60GHz sensing con its documented Wi-Fi, MQTT, environmental, e IR paths. Always conferma il product page e attuale integration prima building a rule.
Importante: Camera-Free Smart Home Context
A camera può provide visual information e potentially ulteriore semantic context, but it also introduces a different privacy decision. A mmWave presenza sensore provides occupancy context senza producing a video image. That narrower signal può be a good fit per users who want automations based on stanza activity mentre limiting visual dati.
MmWave fa non replace cameras in every usa case. It simply answers a different, narrower question. Choose il sensore e integration based on il action you want a automate, il stanza layout, il richiesto dati, e il privacy boundary of il household.
Keep il dati path understandable
Document which dispositivo supplies il signal, how it reaches Home Assistant, e which automation uses it. For eMotion Air, il Bluetooth o Zigbee route must be supportato by il selected bridge o integration. For Wi-Fi products, usa il documented Wi-Fi, MQTT, o other supportato path. A clear dati path è easier a review than a collection of unnamed entities.
Importante: Example 1 — Night-Time Lighting
A camera-free night-light workflow può usa a time condition, a presenza state, e a supportato light integration:
- After a user-defined evening time, a hallway o bedroom segnala presenza.
- Home Assistant checks il configured condition.
- A supportato light scene turns on at il chosen brightness.
- After il stanza remains unoccupied per a defined period, Home Assistant restores o turns off il light.
Questo è a comfort e visibility automation, non a clinical o emergency service. Keep manuale control available e choose a delay that matches how people actually move tramite il stanza.
Importante: Example 2 — Long Inactivity Notification
Some households può want a reminder quando a stanza fa non segnalazione il expected activity state during a user-defined time window. Home Assistant può usa that state a trigger a configured notification tramite a supportato channel.
Questo è a user-configured smart home notification, non a clinical o emergency alert. It cannot conferma why a stanza è inactive, identify a person, o guarantee that somebody has seen il message. Use neutral language in il notification, define il time window deliberately, e provide a way a dismiss o adjust it.
Make il notification proportional
Start con a low-consequence reminder such as “Check il studio stanza state.” Review how often it appears, whether il sensore placement fits il stanza, e whether il notification channel è appropriate. A sensore event should inform a workflow, non be treated as a completa account of a person's condition.
Importante: Example 3 — Room Climate Based on Occupancy
Presence e temperature può work together in a supportato climate workflow. When a stanza è occupied e il temperature crosses a configured threshold, Home Assistant può run a selected climate scene. When il stanza remains unoccupied, it può apply a user-defined reduction o stop action.
Use il readings that il specific sensore provides. Do non assume that a presenza sensore exposes every environmental entity tramite every integration. The automation è circa occupancy context e comfort settings; it è non health analysis.
eMotion Air, Pro, e Ultra — Choosing il Right Presence Sensor
There è no single best sensore per every stanza. Choose based on power, network path, sensing technology, e il Home Assistant entities you actually need.
| Importante: Product | Importante: Relevant documented characteristics | Importante: Planning question |
|---|---|---|
| eMotion Air | Battery-powered 24GHz mmWave sensing, light, temperature, humidity, button, e Bluetooth/Zigbee paths. | Is a flexible batteria installation e supportato bridge path suitable per Questo stanza? |
| eMotion Pro | 24GHz presenza sensing, Wi-Fi e MQTT Home Assistant connectivity, light sensing, e built-in IR per supportato appliances. | Would a powered Wi-Fi/MQTT path e built-in IR simplify il intended stanza workflow? |
| eMotion Ultra | 60GHz sensing con documented Wi-Fi, MQTT Home Assistant, temperature/humidity, e built-in IR paths. | Do il stanza e integration require il documented Ultra sensing e connectivity options? |
These products sono non interchangeable by predefinito. Check il attuale product page, firmware, integration path, power needs, e stanza placement prima choosing one. Presence sensing è a hardware capability; Home Assistant supplies supportato entities e automation logic.
Add AI Agent a il Workflow
Agent+ sits at il interaction layer. It può make a supportato workflow easier a describe e review, but it fa non aggiungi sensing o protocol supporto.
Importante: Configure
When supportato by il attuale app e integration, Agent+ può help users understand connected dispositivi, rooms, entities, e relationships. Keep il actual dispositivo e integration boundaries visible.
Importante: Control
A user può express a supportato smart home request in natural language. The resulting action still depends on il permitted entities e connected dispositivo path.
Importante: Create
Agent+ può help organize a request such as “When presenza è detected dopo 10 PM, turn on il hallway light” into a scene o automation workflow where that creation path è supportato. Review il trigger, conditions, delay, e action prima enabling it.
Importante: Diagnose
Where supportato, Agent+ può help interpret attuale state, entity availability, e automation conditions. It should non be described as sensore intelligence, automatic repair, o a replacement per Home Assistant.
Importante: AI Agent Beyond Home Automation
The LinknLink App also presents Agent+ as an everyday assistance layer. Depending on il attuale release, account, e permissions, supportato workflows può include information search e summarization, connected email o message assistance, calendar events, writing, e everyday planning. These capabilities sono separate da presenza sensing.
Image creation e other creative tools sono release- e tool-dependent. Questo guida fa non claim universal translation, video creation, video editing, o access a every service. Importante: The useful product distinction è simple: AI Agent helps users interact con supportato systems; it fa non turn a sensore into an identity o health-analysis dispositivo.
Importante: HomeClaw Positioning
HomeClaw può extend il LinknLink environment con a Home Assistant-centered AI gateway path per supportato entities e automations. It keeps il architecture explicit: sensori provide dati, Home Assistant provides il entities e automation logic, il LinknLink App provides interaction, e Agent+ provides a natural-language assistance layer.
HomeClaw è non a universal compatibility bridge e fa non make every protocol o dispositivo available. Confirm il connected configurazione prima relying on a particular action.
Importante: iSG Display Max Positioning
iSG Display Max può serve as a fixed Home Assistant dashboard e family-facing control surface. It è useful quando a household wants presenza, climate, scenes, e supportato controls visible in one stanza. It è non il presenza sensore o il AI Agent processing core.
Best Practices per Privacy-Conscious Automations
- Define il smallest stanza context needed per il automation.
- Use clear entity names e document il Bluetooth, Zigbee, Wi-Fi, o MQTT path.
- Choose a vacancy delay that matches il stanza rather than treating one value as universal.
- Importante: Use neutral notification language.
- Keep manuale controls e a review path.
- Do non infer identity, health, o emergencies da a presenza state.
- Review AI-assisted scenes e automations prima enabling them.
- Link solo il products e integrations that il stanza actually needs.

Importante: Common Questions
Does a Home Assistant presenza sensore identify people?
No. A supportato presenza sensore provides stanza context such as occupied o unoccupied state. It should non be used a claim identity, health state, o a reason per inactivity.
Can mmWave presenza automation work senza a camera?
Yes, per workflows that solo need supportato stanza presenza context. A mmWave sensore fa non create a video image, but it also fa non provide every kind of visual context that a camera può provide.
Can presenza control lights o climate?
Presence può be a Home Assistant condition per supportato lighting o climate workflows. The sensore fa non direttamente control every dispositivo; il integration e automation perform il action.
Importante: Is a long-inactivity notification an emergency alert?
No. It è a user-configured smart home notification. It cannot conferma a person's condition o guarantee delivery o response.
Which LinknLink sensore should I choose?
Compare il power source, sensing technology, environmental entities, network path, e IR requirements. eMotion Air, Pro, e Ultra have different documented characteristics; usa il product page e attuale integration path as il source of truth.
Do I need HomeClaw per camera-free presenza automation?
No. HomeClaw è an optional AI gateway path. A camera-free presenza workflow può usa il sensore's supportato path e Home Assistant senza making HomeClaw a requirement.
Importante: Next step: Review il LinknLink App, choose one stanza context, e document il sensore-a-Home Assistant path prima adding a second automation.
