The owner’s guide
Luma is a small light that glows in a colour when something in your routine is due, and stays lit until you tap it. There is no account, no cloud, and no feed — which means almost everything worth knowing fits in the short guide you’re reading now.
Everything runs on the device itself. Your phone and the companion app are remote controls: reminders keep firing with the app closed, the phone off, or the internet down. The only thing Luma needs from your network is Wi-Fi for the clock and for the occasional firmware update you choose to install.
Start
- Setting up — The three ways to bring a new Luma online.
- Finding your Luma — The addresses that work — and the one that doesn't.
Everyday
- Reminders — Schedules, gradients, firing, and the tap.
- Modes — Hydration, Pomodoro, and Vacation.
- PIN & sharing — Locking Luma down, or opening it to the household.
More devices
- Satellites — Adding more Lumas and sending reminders to rooms.
Care
- Updates — How firmware updates are found, installed, and rolled out.
- Recovery & reset — Factory reset, USB recovery, and re-pairing.
- Troubleshooting — Symptom-first fixes for the things that go wrong.

A note on honesty
This guide documents what the firmware and app actually do, including their edges and limits — the reminder cap, what a satellite misses while it’s offline, which addresses resolve and which don’t. Where a behaviour is a deliberate trade-off, the guide says so rather than papering over it.
