One short downlink, and LumioSafe speaks, glows and sounds. It tells people what happened — “Attention! Vehicle seventeen. Compressor stopped.” — not just that something did.
Technical guide How to Choose a LoRaWAN SensorOverview
A siren says something is wrong. LumioSafe says what.LumioSafe is a LoRaWAN® Class C alert beacon for places where a message has to reach people directly. It combines a natural human voice, a bright RGB light and an audible signal in one compact, battery-powered housing that mounts on a ceiling or wall in minutes.
The voice lives on the device. Your application sends only a few bytes — which alarm, which vehicle or zone, which colour — and LumioSafe composes and speaks the full sentence. Because it stays in Class C, the announcement starts within seconds of the downlink, with no audio streaming, no cabling and no app to install.
Built to run unattended, it reports its battery, temperature and state in every uplink, announces its own start-up, network join and low battery, and is supervised by an independent hardware watchdog.
Voice
Says exactly what happened.49 natural voice fragments are stored on the device: system messages, alarm types and the building blocks of every number from 0 to 9999. Your server picks the pieces; LumioSafe reads them out as one sentence.
Light
The whole grille lights up.Four RGB LEDs in the centre window light up the whole housing: the window glows brightest and the colour shines through every hole across the face — visible from across a hall, not just from directly below.
Integration
One downlink. A complete announcement.Light, chime and sentence travel together in a single short message. A webhook or rule on your network server builds it from any sensor event — Willow Software devices or third-party LoRaWAN sensors. Example: 11 bytes on FPort 2 (08 01 03 F2 04 10 F0 00 11 11 23) give a red strobe, a notification chime and “Attention! Vehicle seventeen. Compressor stopped.”
Reliability
Built to work when nobody is watching.An alert device is only useful if it is ready. LumioSafe checks itself, reports itself and recovers by itself.
Installation
Mounts in minutes. No cables.Fix the plate, snap the beacon on, and it joins the network by itself — announcing “Connected, system ready” when it is done.

Ask a questionTypically 2–4 seconds after your server sends the downlink. Most of that is radio airtime; a faster RX2 data rate (e.g. SF9) brings it under two seconds.
Any LoRaWAN 1.0.3 network server, including The Things Stack and ChirpStack. We supply payload formatters for uplink decoding.
Yes. The phrase set is defined per project; we produce your messages in the same voice and build them into the firmware.
Class C keeps the receiver on so alerts arrive instantly, which dominates power use. Battery life depends on your uplink interval and the number of daily announcements — contact us for an estimate for your site.
