Why OGLAS on OGLAS — Off-Grid Local Alert System

Your data is your data

Mon, 01 Jan 0001 00:00:00 +0000

The single biggest design decision in OGLAS is that your data never has to leave your site. The hub logs every sensor reading to local storage, and Local keeps the full record on your hardware. There is no OGLAS cloud account, no monthly fee, no “premium tier” that holds the last 90 days of your history hostage.

What this means in practice

No subscription. Buy the hardware, run it, done. There’s nothing to renew.
No vendor lock-in. Readings are stored in plain text and easily-parsed binary formats. If you want to move them to a different system in five years, you can. If we disappear in five years, you still have everything.
No third-party account. No login, no email-and-password to forget, no app store dependency.
No telemetry. The hub doesn’t phone home. Updates are pulled when you choose, not pushed at 3am.

What we mean by “local”

The hub writes to its own flash, an SD card, or a host you connect (USB, network share, NAS — your choice), and Local runs on your own SBC or laptop. If you want an off-site copy or a remote view, that’s the optional Cloud half — on your own server, your own terms. The decision of where the data goes is always yours.

No telco dependency

A lot of “smart” sensors assume your gate, your tank, and your shed all have decent 4G coverage. Most off-grid sites don’t. OGLAS doesn’t need them to.

How sensors talk

Every OGLAS sensor talks to the hub over long-range wireless — the same class of low-power radio used for everything from livestock trackers to satellite uplinks. Range is measured in kilometres, not metres. Power draw is low enough to run for a season on a single battery.

Monitoring and alerts

Mon, 01 Jan 0001 00:00:00 +0000

Sensors are only useful if someone notices the readings. OGLAS does both halves: a live picture of what’s happening right now, and an audible nudge when something needs your attention.

Real-time monitoring

The hub confirms every sensor message as it comes in, so you can see at a glance which sensors are healthy and which ones haven’t checked in.

Large display — a wall-mount dashboard that pages through every sensor on your network.
Small display — a desktop unit showing your two most important sensors at a glance.
Local dashboard — if you’d rather use a phone or laptop, Local exposes a full web UI on your own network.

All three read from the same on-device log. Nothing leaves your site.

Off-grid power

If your site runs on solar or batteries, every sensor’s power budget matters. OGLAS sensors are designed to spend most of their life asleep, and only the devices that need to listen continuously stay awake.

Battery sensors

The analog node and most “report a reading every minute” sensors:

Run on a single LiPo cell (3.7 V, 1000–2000 mAh is plenty).
Deep-sleep between samples — current draw drops to microamps.
Wake, read, send, wait for confirmation, sleep — the whole cycle is under a second of activity per minute.
Survive a full season on a charge for typical reporting intervals; longer with solar trickle.

We select hardware specifically for ultra-low deep-sleep current on battery-powered sensors. Slightly higher-power variants are available for always-on devices — pick the one that suits your install.
