How it works
No app. No wearable. No phone on the nightstand. Restarla works out of the box with two dials and a bit of radar magic.
Use the two physical rotary dials on the lamp to set a wake-up window — for example, 6:45 AM to 7:15 AM. The embedded display confirms your settings. No screen, no app, no Bluetooth pairing.
Left dial sets the earliest time, right dial sets the latest
Tactile click-detents so you can set times in the dark
Small embedded display shows the current window and time
Once your window is set, the lamp's built-in 60 GHz radar sensor begins passively monitoring your movement and breathing patterns. It works through your duvet — no contact, no sensors attached to your body.
60 GHz FMCW radar senses micro-movements and respiration
Works through duvets, blankets, and bedding
On-device processing — no cloud, no data leaves the lamp
No wearable to charge, no phone to place on the mattress
As your wake-up window approaches, Restarla monitors your sleep cycles in real time. When it detects you've entered light sleep — the easiest stage to wake from — it starts a gradual sunrise simulation.
Light begins as deep amber (1800K) and warms to soft white (3000K)
The transition takes 15–20 minutes, mimicking a natural sunrise
If you're in deep sleep, it waits — never waking you mid-cycle
If the window ends, a gentle audio tone activates as a failsafe
Instead of the jolt of an alarm ripping you out of deep sleep, you wake gradually to warm light filling the room. Your cortisol rises naturally. You feel alert instead of groggy. It's the way your body was designed to wake up.
Waking during light sleep reduces sleep inertia by up to 80%
Gradual light exposure supports healthy cortisol awakening response
No adrenaline spike from a sudden alarm — just calm alertness
