No morning activity
You set a latest-by time — for example “Mum is usually up by 9:30am”. If EinerDa has detected no movement by then, a push notification goes to you and the contacts you chose.
Available late 2026 · Limited first batch
So you can know
that all is well.
EinerDa quietly senses whether a loved one is at home and moving — and lets you know if something doesn’t add up.
No camera. No microphone. No feeling of being watched.
Sensor · App · instant notification — set up in three minutes
The name
EinerDa
The name plays on the German question «Einer da?» — «Anyone home?».
The app answers, quietly: «Mom is home.» Or «No one is home.» That’s all you need to know.
Form meets function
Small.
Discreet.
There when you need it.
13 cm across, 4 cm tall. Fits on any sideboard, into any bookshelf, beside any vase. Black, matte, calm — so unobtrusive that the person it protects barely notices it.
One status LED.
That’s all it needs.
At the front, slightly recessed: a tiny green dot. It only says “I’m awake”. No blinking lights, no sounds, no display. The reassurance lives in your hand — on your phone.
Plug in & forget.
One outlet is enough. No battery to fail. No maintenance ritual. A power draw you barely notice on standby. EinerDa runs as quietly and reliably as a good fridge.
A simple idea
When someone you love
lives far away, you sleep less.
We built EinerDa because the question “Is Mum okay?” shouldn’t turn into a 7am phone call every morning. Or that sinking feeling at night when nobody picks up. EinerDa turns “I hope so” into “I know so”.
Three situations. One notification.
When the morning stays unusually quiet,
you should be the first to know.
EinerDa watches for three patterns that matter in the daily life of an older or vulnerable person — and alerts you exactly when one of them tips.
No movement — possible fall
Present but motionless for an unusual length of time. The sensor tells the difference between watching TV quietly and a stillness that isn’t normal — and raises the alarm in time.
Unusually long away from home
When no one has been detected in the living space for an unusually long stretch — say, more than 12 hours — EinerDa raises a flag. You decide the threshold.
Who EinerDa is for
Four people. Four stories.
One shared peace of mind.
Parent living alone
“Mum lives 200 km away — and she’s 84.”
Beat calls her briefly every morning. When nobody picks up, the worry starts — is she out, still asleep, or has something happened? With EinerDa, he sees on his phone: 7:42am, movement in the kitchen. All good. Sunday’s call becomes a conversation again, not a check-in.
- Morning routine as the main trigger
- Push to the sibling group’s phones
- Mum barely notices the device
After a fall / rehab
“Dad is shaky since his fall.”
After three weeks in hospital, Heinz wants his independence back. His daughter doesn’t want to surveil him — but she needs to know if he falls again. EinerDa spots when someone is present but motionless for hours, and raises the alarm in time, before hours go by.
- Fall trigger active, 2-hour threshold
- Alert routed to home-care service + daughter
- Dad wears nothing, pushes no button
Person with disabilities
“My brother lives semi-independently.”
Lukas has a cognitive impairment and lives semi-independently. A camera is out of the question for the family — too invasive, too much pressure. EinerDa gives the family only binary information: is he there, is he moving. Dignity stays, safety is added.
- No image, no audio — nothing is recorded
- Push to parents and support staff
- Daily rhythm adapted to the weekly plan
Partner at home
“My wife has a chronic illness.”
While Renato is at work, Sandra is at home alone. She doesn’t want to keep texting in — and he doesn’t want to keep asking. EinerDa shows him hour by hour: movement within range. Anything out of the ordinary, he hears about immediately.
- Multiple rooms, one sensor each
- Alert to partner only — no external chain
- Full history visible in the app anytime
One small device.
One big, good feeling.
EinerDa sits unobtrusively in the living space — on a sideboard, on the bookshelf, in a wall outlet. It communicates one thing only: that all is well.
The app
Three screens. That’s all
you need.
No endless menus. No daily charts. A clear answer — and a message only when one is truly warranted.

Privacy — radically different
Nothing needs to be
recorded for you
to feel reassured.
Other solutions film, listen in or send every step to a corporate cloud. EinerDa measures only one thing: is someone in the room right now, and are they moving?
That signal cannot identify people. It cannot reconstruct conversations. It cannot tell whether someone has guests — only whether there is life in the room.
- No camera image — there is no optics inside the device.
- No microphone — there is no audio input.
- Speaks on your home network — direct app access, no cloud lock-in.
- Cloud push is optional — and end-to-end separated from the sensor signal.
- Your data is yours — no sale, no tracking, no profile.
- Open architecture — source code and spec are inspectable.
Set up in three minutes
How it works.
EinerDa is not a DIY project. Unbox, plug in, open the app — done. No installer. No contract. No incomprehensible menus.
-
01
Unbox & plug in
Plug the sensor into the wall outlet in the living space. A small green LED confirms the device is ready. Placement isn’t critical — what matters is that it can “see” the room.
-
02
Install the app & pair
EinerDa app from the App Store or Google Play. Bluetooth pairing detects the sensor automatically, you enter your Wi-Fi password once — and it’s online.
-
03
Pick triggers & contacts
You set when an alarm makes sense (morning time, fall threshold, away duration) and who should be notified. Push, email, optionally SMS.
How the data flows
From the living room to your hand. Directly.
Four stations, clearly separated. You see — and control — every step.
Sensor in the room
Contactless sensor detects motion & presence. No images, no audio.
Local processing
On-device, the signal condenses into “present / absent / moving”.
Secure push relay
Only alarm events go encrypted to Apple/Google. No history.
Your family
Push, email, optionally SMS. You choose who learns what, and when.
Launch
Late 2026.
The first devices ship before Christmas to families on the early list. Limited first batch — being early means priority and the launch price.

Frequently asked
Sounds maybe too simple.
It isn’t.
Does EinerDa film or listen in?
No. There is no optics and no microphone inside the housing — we physically cannot record anything, even if we wanted to. The sensor delivers only the answer to “is someone moving right now”.
Do I need internet for it to work?
For push notifications to your phone: yes. Inside your home network EinerDa works fully without the cloud — you can connect directly over Wi-Fi and see status. The cloud is used only as a postal service for alarm messages.
Is there a subscription or monthly cost?
No. You buy the device once. App, updates and push notifications are permanently included. Should we ever offer paid premium features, the core stays free for existing customers.
How fast is EinerDa to set up?
Three minutes. Plug it in, open the app, enter the Wi-Fi password. In setup mode the device speaks to your app directly over Bluetooth — no keyboard, no screen, no installer needed.
What happens during a power or Wi-Fi outage?
As soon as power and network return, the device reconnects automatically. If it stays offline for an extended period, you get a notification — so you don’t mistake a quiet sensor gap for “all good”.
Can I manage multiple devices and multiple homes?
Yes. One app, multiple sensors, multiple people, multiple locations. Siblings can share the same sensor and both receive notifications.
Who is behind EinerDa?
EinerDa is built in Switzerland by an independent team of engineers, with input from care professionals. No corporate parent, no data-hungry investor.
What will EinerDa cost?
We publish the final price together with the launch. Those who sign up today get an early-bird price and a reserved unit from the first production batch.
