Monitoring on OGLAS — Off-Grid Local Alert System

Smoke & Gas

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

A smoke alarm nobody can hear from the house is no alarm at all. The OGLAS Smoke & Gas sensor puts detection in the buildings that matter on a remote site — and gets the alert to you wherever you are.

What it does

Detects smoke — early-warning detection in sheds, workshops, and stores well away from the house.
Detects combustible gas — LPG, methane, and the like, around gas stores and pump houses.
Detects toxic gas — carbon monoxide in a generator shed or workshop.
Alerts immediately — straight to the bell, every bell on site, and (with Cloud) a push to your phone. This is the message that doesn’t wait.

Honest scope

This is monitoring and early warning for remote, unattended buildings, not a replacement for the certified smoke alarms your dwelling is required to have. It covers the sheds and outbuildings those alarms never reach.

Engine

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

An engine that never moves still wears out — and the backup generator nobody logged is the one that won’t start when you need it. The OGLAS Engine sensor brings the Vehicle Track run-log to fixed engines: generators, pump engines, compressors, anything that runs in place.

What it does

Detects runs — from the engine’s accessory output, a vibration sensor, or current on the load. Every run is logged with start time and duration.
Counts hours — accumulated run-time per engine, so service intervals are by hours, not by a date someone guessed.
Trends battery and starting — for engines that fail to crank, the battery is usually the culprit; trend the voltage and you’ll see it coming.
Flags exercise gaps — is the backup genset actually being run monthly, or has it sat idle since spring?
Raises service alerts — hours-since-service past the limit rings the bell or pushes a notification.

Why it’s its own sensor

It shares the run-log engine with Vehicle Track — the difference is the trigger and the fact that GPS doesn’t move. For anything with a cab and a journey, use Vehicle Track; for a genset bolted to a slab, use this.

Noise

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

Sound is a surprisingly good sensor. The OGLAS Noise sensor reports a sound level — not a recording — so you can tell, from anywhere, whether something is running, alarming, or happening when it shouldn’t be.

What it does

Measures sound level — ambient dB over time, with thresholds you set.
Detects “running” — a pump, compressor, or generator is audibly on; pair that with Power Monitoring to confirm it’s working.
Detects “alarming” — another alarm sounding (a separate smoke alarm, a reversing beeper, a siren) becomes an OGLAS alert.
Detects “activity” — noise in a yard or shed that should be quiet overnight.

It reports a level and threshold crossings only — no audio leaves the device, which keeps it private and keeps the data tiny — see Your data is your data.

Weather

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

The forecast for the nearest town is not the weather in your back paddock. The OGLAS Weather sensor is a station that reports your conditions to your own hub — and feeds the rules that act on them.

What it does

Temperature & humidity — ambient conditions, logged continuously.
Barometric pressure — the leading indicator of a change coming through.
Rainfall — a tipping-bucket gauge totalising what actually fell on you.
Wind speed & direction — for spraying windows, fire days, and structure-load awareness.

All of it lands in the same dataset as your other sensors, so “it rained 12 mm” sits next to “the tank rose 40 mm” and “the soil came up to field capacity”.

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.

Power Monitoring

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

Power Management reads your solar charge controller. Power Monitoring reads everything else — because plenty of off-grid power doesn’t come from a Victron MPPT.

What it does

Reads any source — mains feed, generator output, a battery bank via a shunt, or an individual circuit. AC or DC.
Measures voltage, current, and energy — instantaneous draw and accumulated kWh, per source or per circuit.
Finds the hogs — which load is quietly eating your battery overnight, and which circuit’s draw is creeping up.
Logs locally — every reading to your hub in open formats, no utility portal — see Your data is your data.

Hardware

Current transformers (AC) or a DC shunt feeding an OGLAS node, sized to the circuit. Multiple channels for a switchboard; a single channel for one load.

Temperature

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

Not every temperature is the weather. The OGLAS Temperature sensor watches a specific point — and tells you the moment it leaves the range it’s supposed to be in.

What it does

Reads one or more probes — a single point or several on one node.
Alerts on thresholds — too warm, too cold, or out of a band, straight to the bell or your phone.
Logs the trend — so you can see the freezer creeping up for a day before it actually failed.

Where it goes

Freezer & cool room — the classic: catch a failure before the contents spoil.
Water tank & hot water — frozen-pipe risk at one end, legionella-safe storage at the other.
Kiln, oven, smoker — confirm a firing or curing schedule held.
Engine & bearing — an overheating bearing or engine as an early fault signal.
Glasshouse & shed — keep growing or stored goods in range.

Hardware

Thermistor, RTD, thermocouple, or a digital probe (DS18B20 and friends) to suit the range, on an OGLAS analog-class node. Mains or battery depending on the site.

Trap Trigger

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

Checking traps is the same problem as checking troughs: a long drive, mostly to find nothing. The OGLAS Trap Trigger sensor tells you the instant a trap fires, so you only make the trip when there’s a reason to — and you make it quickly.

What it does

Detects activation — a switch or sensor on the trap mechanism fires the moment it’s triggered.
Alerts immediately — straight to your hub, the bell, the cab display, or your phone via Cloud.
Time-stamps and locates — when it fired, and (with GPS) which trap, so you go straight to it.
Runs for months — it sleeps and waits for a single event, so battery life is measured in seasons.

Why it matters

For pest and feral control, a sprung trap left for days is both ineffective and inhumane. Knowing within minutes means you can dispatch or release quickly, and reset the trap so it’s working again sooner.

Water Flow & Pressure

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

Level tells you how much water you have; flow and pressure tell you what it’s doing. The OGLAS Water Flow & Pressure sensor sits inline and watches the things that go wrong between the source and the tap.

What it does

Measures flow rate — litres per minute through a line, totalised over time so you know exactly how much moved.
Measures line pressure — at the pump or anywhere on the line.
Catches leaks — flow when nothing should be running is a burst pipe or a stuck valve, and it raises an alert straight away.
Catches blockages and a tiring pump — pressure climbing or falling outside its normal band points to a filter, a kink, or a pump losing its prime.

Hardware

An inline flow meter (pulse or analog) and a pressure transducer, read by an OGLAS node and reported to your hub. Runs from the same supply as a nearby pump, or battery + solar for a remote line.

Frost

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

A frost you find out about at dawn is a frost you’ve already worn. The OGLAS Frost sensor watches the conditions that lead to one and warns you — and your gear — in time to act.

What it does

Tracks air and ground temperature — at canopy and at ground level, where frost actually settles.
Reads dew point — temperature plus humidity tells you how close you are to forming frost, not just how cold it is.
Warns early — an alert as conditions approach the threshold, not once the damage is done.
Triggers protection — fire frost fans, an under-tree sprinkler, or a heater via a Smart Switch, automatically, at 2 am, without you standing in the cold.

Hardware

Paired temperature probes (air and ground) and a humidity sensor on an OGLAS node, sited in the block you’re protecting. Battery + solar — see Off-grid power.

Air Quality

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

The OGLAS Air Quality sensor watches what’s in the air where people, animals, or plants are — and raises the alarm when a level climbs into a range that matters.

What it does

CO₂ — ventilation and comfort indoors; growth in a glasshouse; build-up in a confined space.
Methane (CH₄) — biogas, manure pits, and stores; this one also overlaps Safety (it’s combustible).
Particulates (PM2.5 / PM10) — dust, smoke haze, and air quality on fire-season days.
Temperature & humidity — the context every air reading needs.

Levels log to your hub with alerts on threshold, and can drive ventilation directly.

Water Quality

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

Plenty of water is no good if it’s the wrong water. The OGLAS Water Quality sensor monitors the condition of what’s in your tanks, troughs, dams, and tanks for stock, irrigation, or aquaculture.

What it does

pH — drift outside the safe band for stock, crops, or fish.
Salinity / EC / TDS — dissolved solids creeping up in a bore or dam.
Temperature — drives dissolved-oxygen levels in aquaculture and dam health generally.
Turbidity — cloudiness from algae, runoff, or a disturbed dam.
Dissolved oxygen (option) — the one that matters most for fish.

Readings go to your hub on a schedule, with alerts when any value leaves its safe range.

Custom Builds — Sensors, Hubs & Data for Any Site

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

Most of what’s on this site — the sensors, the hubs, the local and cloud tooling — exists because we built it for a real site that needed it. That’s the actual product: custom monitoring, end to end, for places where nothing off the shelf fits.

If you run a large or unusual site and you’ve got something that needs watching, switching, or understanding — and the commercial IoT platforms either don’t cover it or want a subscription per device to do so — we can build the thing that does.

Local — Own and Analyse Your Data On Site

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

Local is where your data becomes something you can actually use. It runs on hardware you already have on site — a small SBC tucked next to a hub, or a laptop or desktop you open when you want a proper look — and it turns the stream of sensor readings into dashboards, history, and answers.

The whole point: the data is yours, it stays local, and nothing has to leave the site for you to get full value from it. Cloud is an optional extra on top — Local is complete on its own.
