DISPLAY & LIGHT

A screen that never flickers,
a light that fades in.

NODBOT uses no always-on LCD and produces no blue light. It shows information in electronic ink and mimics sunrise with full-spectrum LEDs. The information is still; the light is slow.

Display: 4-inch E-ink paper400 × 300 · flicker-free · keeps the image without power · zero-power standby
Grayscale: Varies by editionPURE standard black-and-white / ODYSSEY dark base / HERITAGE 4-level grayscale
Lighting: SunLike full-spectrum LEDCRI ≥ 95 · 4000K ± 200K · flicker-free · low blue-light certified
Night light: 2700–3000K warm lightbrightness and colour temperature follow the sleep cycle
Ambient adaptation: All editions adapt to ambient lightscreen and light adjust to room brightness without glare

Electronic ink is not only about saving power. It does not light up the room, refresh blue light, or suddenly flash a "notification" at midnight. The information stays there — look or don't, it never intrudes.

SPATIAL SENSING

It senses presence,
not identity.

NODBOT has no camera. It relies on time-of-flight (TOF) LiDAR, with HERITAGE adding mmWave radar, reading distance, micro-motion and the tiny displacement of breathing to understand what is happening in the room.

TOF LiDAR: Standard on all editionsreal-time distance sensing; recognises approach, waves and operating intent
mmWave radar: HERITAGE only24GHz, fused with TOF; millimetre precision and gesture prediction
Gesture range: About 60 cmwave to browse or switch panels; hold an open palm for 0.5 s to mimic an approach wake
Mounting distance: About 20 cm above the mattresson the nightstand facing the bed, with nothing in front
Two people / pets: Distinguishes two sleepers in one bedfilters interference from a partner or a pet
Camera: Noneno image is captured at the physical layer

Radiation safety: 24GHz radar intensity is about 1/52 of the WHO public limit; 940nm infrared power is 18× below the IEC-60825 eye-safety line. These are internal specifications; final figures follow the shipping unit and third-party testing.

PRIVACY-FIRST

Invisible at the physical layer,
nothing retained at the data layer.

Privacy is not a setting; it is an architectural premise. How NODBOT captures, stores and connects decides that it is "incapable" of uploading your bedroom anywhere.

No camera

Only TOF LiDAR and mmWave radar. No lens, no image sensor, no infrared imaging.

Local storage

Conversations, sleep records and preferences stay on the device. Long-term memory lives at home, not in someone's data centre.

Zero cloud retention

The server retains no personal sensitive data. Core features do not depend on the cloud being online.

Encrypted local link

App and device connect directly and encrypted on the same Wi-Fi (LAN) — data never leaves the house and is never relayed through a server.

Pairing takes one time

After power-on, a blinking blue LED means it is waiting to pair. Choose the same Wi-Fi (2.4GHz) in the App, enter the password, and tap Pair under device management; a steady green LED confirms success. After that you can use it without a phone. On iOS, open the local address shown on the device display and trust the certificate; on Android, use the official App.

The data is yours to dispose of

The App includes a data map showing what stays only on the device and what never goes to the cloud, with one-tap export and deletion. You can take your "memory" with you at any time — or make it disappear entirely.

SLEEP MONITORING

Measure as you lie down,
nothing to wear.

No ring, no band, no phone by the pillow. NODBOT reads breathing and micro-motion through radar, recording time to sleep, sleep duration and sleep stages.

Method: Contact-free radarmmWave + LiDAR (HERITAGE); TOF only (PURE / ODYSSEY)
Metrics: time to sleep · sleep duration · light / deep / REM cycles
Shared bed: Distinguishes two sleepersfilters a partner or a pet
Staging basis: REM staging aligns with Apple Health datainternal specification; external claims follow third-party testing
AI interpretation: MOE model analysispresented as narrative advice, not a pile of metrics and scores

Important: Sleep tracking and sleep staging are for everyday wellness management and lifestyle reference only. They do not replace polysomnography (PSG) or any professional medical device, and must not be used for medical diagnosis, treatment decisions or clinical monitoring. NODBOT makes no "medical grade" claim and publishes no "accuracy > 85%" figure.

GENTLE WAKE

You are not roused.
You are woken.

A traditional alarm does one thing: it interrupts you at a fixed time. NODBOT combines your long-term sleep pattern, waits for you to return from deep sleep to light sleep, and then lifts you gently with light, melody and voice.

Adaptive timing: Waits through deep sleepuses long-term sleep patterns to wake in a better stage
Sunrise simulation: SunLike full-spectrum gradual brighteninglight instead of a sonic jolt; colour temperature and brightness rise together
AI wake score: Personalised melody generated in real timeevery wake is a unique phrase; samples can be heard in C-Tone 3.0
Human-like voice: Natural spoken calladjustable tone and wording, no mechanical chime
Contact-free snooze: An open palm or a turn activates itno need to touch the device or hunt for a button in the dark
Getting-up detection: Detects whether you are truly upstanding up plays a different cue, giving the morning a sense of ritual

The creation and validation platform for wake scores is C-Tone 3.0: 7 complete tracks, a verifiable score syntax, and in-browser playback. It is both a sample library of the product's capability and a melody you can rewrite yourself.

DUAL SCENARIO

A desk by day,
a bedside at night.

One interaction language, two very different kinds of restraint: at night it may speak; by day it never interrupts.

MODE 01 · DAY · Desk mode

Placed on a desk, facing your seat, with nothing in front of it. It offers sedentary and hydration reminders, eye-care lighting (a blue-light-free lamp) and guided meditation breaks; it shows the date, weekday and holidays for multiple regions; temperature, humidity, network and alarm status are visible at a glance.

MODE 02 · NIGHT · Bedside mode

Placed on a nightstand, facing the bed, about 20cm above the mattress. It offers contact-free sleep tracking, a sunrise wake light, adaptive white noise and dream mode. Interaction is voice, light and contact-free gestures.

Placement: Once positioned, the device is not moved. Covering both a daytime desk and a bedside at night requires two devices; a single unit serves only its own scene. We make no "one unit covers 16 hours a day" claim. The first 2 days after placement are the golden window for the spatial snapshot, so keep the position unchanged.

E-INK & WIDGETS

One restrained little screen.

NODBOT's desk widgets run on a fixed black-and-white canvas. It fits only one large number and at most three lines of labels — which is the point: one glance up and you know your day. Canvas specifications evolve with the hardware; the shipping unit prevails.

Canvas: Fixed canvasno scrolling, no wrapping; 2–3 information groups per screen
Colour: Pure black / pure whiteno gradients, no anti-aliasing, pixels on the integer grid
Stroke and type: stroke ≥ 2px, type ≥ 16px
Tag whitelist: div / row / text / progress / svg≤ 48 tags per widget
Data interfaces: ≤ 3 APIsrefresh every 1–120 min, flash alerts, automatic fallback on validation failure
Store: A growing catalogue of desk skillspreview and one-tap deploy; target 200+

Why black and white

The value of E-ink is that it does not emit light. Introduce colour and gradients and it becomes a dimmer, slower LCD. So the widgets stay monochrome and vector-based, with heavy strokes and large type, readable from any angle and in any light.

AUDIO & BODY

Retuned for the night.

White noise, stories and wake melodies need a quiet chamber. NODBOT uses a sealed bass chamber and dual microphones so sound stays complete even at low volume.

Speaker: 180Hz bass speakersealed bass chamber (BASS cavity)
Microphones: Dual microphonesvoice interaction and ambient sensing
Body material: Polycarbonate shell + solid wood insetanti-yellowing, scratch-resistant coating; hard maple / North American black walnut
Dimensions: 13.5 × 11.5 × 8.0 cm
Weight: 260 g
Construction: Screwless minimal structureserviceable, not glued shut
Design life: 5–10 yearsmaterials chosen for long companionship, not one-off consumption

The wood inset is a natural material; grain and colour are never identical between units. This is not a defect — it is the premise of living alongside it.

CONNECTIVITY

It connects.
It can also stay offline.

Pair once; the phone is not needed afterwards. The App is a window for viewing and managing, not a prerequisite for the device to run.

Wi-Fi: 2.4GHz5GHz not supported; the App and the device must share one network
Bluetooth: Supportedinitial discovery and proximity pairing
Port: USB Type-Ccharging and data transfer
Power: Fixed USB-C supply5V / 1A adapter or above; no battery, no charge cycles
App: Raychel Appsleep reports, health trends, device management, data export and deletion
Subscription: No mandatory hardware subscriptionno paywall on core features; token costs are borne by NETVERSE

No battery means it is never interrupted by "forgotten charging", and never retires early because the cell aged. It needs only a fixed USB-C supply — like a bedside lamp.

OPTIONAL · PROJECTOR

Hand the night ceiling
to a field of stars.

Raychel Projector is an optional accessory, not part of the main unit. It projects onto the ceiling — the more natural viewing direction for someone lying in bed.

Projection: Integrated short-throw projector270° angle adjustment, ready on power-on
Content: 200+ dynamic scenesocean, forest, campfire, starfield and more, continuously updated
Interaction: gesture switching · AI voice generation · auto activation
Auto sleep: Turns off after detecting the user has fallen asleep
Content service: Includes a free AGI visual-content generation subscription
Price: $199bundles are combined-offer pricing

SETUP & CARE

Getting the position right
matters more than the settings.

Radar sensing is sensitive to placement. Positioned well, both accuracy and experience improve; positioned badly, even a good algorithm is compromised.

Bedside mode

Place it on the nightstand, facing the bed, with no obstruction in front of the device.
Keep the device roughly 20cm above the mattress and at a natural distance from the bed edge.
Once fixed, avoid moving it; the first 2 days after placement are the golden window for the spatial snapshot.

Desk mode

Place it on the desk facing your seat, with the screen roughly level with or slightly below eye line.
Avoid facing strong window light or an air-conditioner outlet, so ambient light and temperature/humidity readings stay accurate.
Keep the USB-C supply stable and leave some slack in the cable.

Everyday care

Clean the screen and shell with a dry, soft, lint-free cloth; avoid alcohol and abrasive cleaners.
Avoid prolonged direct sunlight, damp and high temperatures; do not immerse the wooden inset in water.
Firmware updates arrive over OTA; keep power and network connected during an update.

CERTIFICATION & SAFETY

The certifications it needs,
and the boundaries worth stating.

NODBOT provides the radio and electrical compliance certifications required in each sales region. It is not a medical device; sleep and health data are for everyday lifestyle reference only.

Radio compliance: FCC / CE and other regional certificationprovided per sales region; see the packaging and manual for numbers
Radar exposure: 24GHz, about 1/52 of the WHO public limit
Infrared safety: 940nm, 18× below the IEC-60825 eye-safety line
Medical certification: Nonesleep and health data are for everyday reference, not medical advice
Data compliance: local storage · zero cloud retentiondesigned for GDPR and similar regional requirements
Firmware: Ongoing OTA updatesthe version shown on the device and in the App prevails

LEGAL & FOOTNOTES

Disclaimers & footnotes

¹ Product prices, promotions and stock are shown live on the online store page; this page is not a price commitment.

² Display specifications differ by edition: PURE uses standard black-and-white E-ink; ODYSSEY uses a dark-based E-ink; HERITAGE uses 4-level grayscale E-ink. The E-ink panel renders only pure black and pure white, with partial refresh prioritised.

³ TOF + mmWave radar dual-sensor fusion is exclusive to HERITAGE. PURE and ODYSSEY carry a single-sensor TOF LiDAR. The device contains no camera.

⁴ Sleep staging and sleep-stage analysis are for everyday wellness management and lifestyle reference only. They do not replace polysomnography (PSG) or any professional medical device, and must not be used for medical diagnosis, treatment decisions or clinical monitoring. REM staging data supports Apple Health sync; actual performance is subject to third-party testing.

⁵ "5–10 year design life" is a design target and a statement of material selection; actual life depends on the operating environment and care.

⁶ Product images are industrial renders; colour, texture and on-screen content of the physical unit may differ. Wood insets are natural material, so grain and colour cannot be identical.

⁷ All conversations, sleep records and preferences are stored on the device; the cloud retains no personal sensitive data. Value-added content services are named separately and never gate core features; the hardware carries no mandatory subscription.

⁸ The C-Tone score collection is a design and music-creation reference: two classics are transcriptions of public-domain themes, the rest are original melodies. Confirm copyright and legal requirements before any specific use.

⁹ Once positioned, the device is not moved; covering both a daytime desk and a bedside at night requires two devices. A single unit serves only its own scene.

¹⁰ Radiation and safety figures follow the shipping unit and third-party testing. Certification types and numbers are provided per sales region; see the packaging and manual.
