The Rockloop Wave is a 24 GHz mmWave presence sensor that keeps the lights, heat, and automations on while you're reading, working, or watching TV — not just while you're waving your arms at a motion sensor.
No hub to buy. No account to create. No subscription, ever.
Fully refundable any time before yours ships — plus 30-day returns after delivery. Reserve today — prepay at checkout and your unit ships first, ahead of unpaid reservations no matter when they were placed — or join the mailing list free.
A PIR motion sensor only sees movement. Sit down with a book and, to your smart home, you vanish — lights out mid-chapter. mmWave radar sees the micro-movement of breathing, so presence stays true.
The Wave's 24 GHz radar picks up breathing and micro-movement up to ~6 m away. Reading, desk work, TV on the couch, a sleeping baby — presence stays occupied the whole time, and your automations behave.
24 GHz mmWave radar (HLK-LD2410C) senses presence — not just motion — including people seated, working, or asleep.
Built on ESPHome and an ESP32-C3. It appears in Home Assistant as a proper local device — no vendor app in the middle.
Wi-Fi direct to your network. The $24 “cheap” rivals quietly need a Zigbee coordinator before they do anything.
No account, no cloud round-trip, no data leaving your house. It keeps working when your internet doesn't.
Presence plus ambient context for the automations people actually want: lights that stay, HVAC that knows, alerts that matter.
At launch, pick a preset in Home Assistant — Bedroom, Living Room, Office, or Pet-Friendly Home — instead of hand-tuning sensitivity numbers. Set up in minutes; fine-tune later only if you want to.
Launch firmware lets you turn the status LED completely off from Home Assistant. No glow on the wall at night — check status in the app instead.
Email gets answered by the person who built the Wave — not a ticket queue. Real help with placement, presets, and automations, in plain English.
Prices shown are the list / widely listed prices from competitor product pages as of October 2026. Features are the ones that decide whether a presence sensor actually works in a real room.

*Noted by FP400 owners in Home Assistant community discussions, October 2026: zone and people-count data stays in the Aqara app and reaches Home Assistant with delay. The Wave exposes its data locally, in Home Assistant, from day one.
The Wave is built for Home Assistant first — that's the hub its buyers already run. From Home Assistant, its occupancy sensor can be exposed onward to the other platforms, so you’re not locked out of the apps your household already uses.
Direct and native via ESPHome. The Wave appears in Home Assistant as a local device over Wi-Fi — presence, automations, dashboards, and history, with no vendor app in between.
Expose the Wave from Home Assistant using the built-in HomeKit Bridge and it appears in the Apple Home app as an occupancy sensor — for scenes and automations alongside your other HomeKit devices.
Share the Wave from Home Assistant to Google Home or Alexa — via Home Assistant Cloud for the one-tap route, a manual setup, or a local Matter bridge add-on — and use its occupancy in routines and voice-driven homes.
The same bridge route carries the Wave into Samsung SmartThings and other platforms that can see Home Assistant devices — useful for mixed-platform households that still want one local sensor at the source.
Platform names and trademarks belong to their owners. Compatibility above describes the through–Home Assistant route available at launch; official platform certification badges will only be used if and when a future model is certified.
Demo units are going out to smart-home creators ahead of launch. Their hands-on videos will live right here — unscripted, their words, not ours.
Reserve now — prepay (refundable) at checkout — or join the free mailing list.
Free units to smart-home YouTubers for independent hands-on reviews.
Pre-order numbers set the size of the first run — prepaid orders ship first when it's done.
Prepaid pre-orders ship first — ahead of unpaid reservations, no matter when they were placed. Mailing list gets first public-stock access after that.
Prepay to lock your place at the front of the shipping line, or join the mailing list and decide when launch is real. No pressure either way — but when units start shipping, prepaid customers go first.
Reserve your Wave from the first run, shipping in order from January 2027. Start with one room at $54 — or cover more rooms for less per unit with a pack below.
Multi-room packs — the step-up
Presence pays off room by room. Packs keep the same $54 single as the starting point and lower the per-unit price when you cover more of the house.
Bundles follow the same rules as singles: fully refundable any time before shipping, 30-day returns after delivery, and prepaid bundles ship first under the paid-priority policy.
How prepay works: your payment is collected immediately at checkout, securely through Stripe — that's what locks your price and your place at the front of the shipping line. If anything about the timeline changes, your refund right doesn't — full refund any time before your unit ships, plus 30-day returns after delivery. Prepaid orders ship first, ahead of unpaid reservations. Sales tax is calculated at checkout where applicable. Singles and packs follow the same terms, and prepaid packs ship first just like prepaid singles.

Presence only pays off room by room — living room + office is the classic pair. Use the packs in the pre-order card: 2-pack $99 ($49.50/unit, save $9) or 3-pack $139 (about $46.33/unit, save $23), with the same refund and ships-first terms as a single.
We're sending free Wave demo units to smart-home YouTubers ahead of the January 2027 launch. No script, no talking points, no “positive coverage” clause — if you find a flaw, that's the most useful review we could get.
Pre-production Wave with the same hardware as the launch unit.
Every published hands-on gets a slot in the Videos section above and a shout in the launch email.
Questions, firmware quirks, weird-room edge cases — you talk to the person who built it.
Tell us about your channel. Units are limited per wave, so subscriber count matters less than a smart-home audience that trusts you.
Submitting generates a saveable request summary for your records. We reply to every request — if a wave is full, you're first in line for the next one.
