Control on OGLAS — Off-Grid Local Alert System

Door / Gate

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

The OGLAS door / gate node knows two things: when something is open, and how to open it on command. A paddock gate, a shed door, a depot roller door — same node, same wireless link as the rest of your sensors.

What it does

Detects open/closed state — a reed or limit switch on the frame trips the device, which immediately reports the state change to your hub.
Opens on command — a signal from the hub (or a button in your vehicle) pulses an output that drives your motor or relay. You can open a single door/gate or every one at once.
Reports when it’s done — confirms back to the hub so you know the action ran.

The matching bell can ring a buzzer indoors the moment it trips — works as well on a farm entrance as on a yard gate or a shed left open overnight. See Monitoring and alerts.

Smart Switch

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

The OGLAS Smart Switch is the active end of the network. Where the other sensors measure and report, the Smart Switch acts — turning a load on and off based on conditions you’ve defined, and reporting back not just whether it switched but whether the load is actually working.

What it does

A Smart Switch decides whether to be on or off using one or more of:

Power-management data — reads incoming watts, battery state, and load from a power-management sensor (e.g. Victron MPPT). Run the relay on stable solar surplus.
Sensor data — subscribe to readings from other OGLAS sensors. Tank dropped below 200 mm? Soil moisture below threshold? Battery bank above 90 %? React.
Web / API data — when Wi-Fi is available, pull from a local server, MQTT broker, or HTTP endpoint. Used for off-property triggers that need external data.
Weather data — forecast and current conditions from a weather API. “Run only when the next 6 hours are clear” is one rule that uses this.

Multiple inputs combine with AND/OR rules in the device config. None of this requires a cloud account — see Your data is your data.

Water Pump

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

The OGLAS Water Pump controller starts and stops a pump on the conditions you set — a tank dropping, a trough low, solar surplus available — and, crucially, confirms the pump actually ran by measuring its current. It’s the Smart Switch tuned for the one job that matters most on a dry site.

What it does

Drives the pump on a rule — start when a tank or trough drops below a threshold; stop when it’s full. Combine with solar surplus so the pump runs when there’s sun to spare.
Confirms it ran — current sensing tells you the motor actually drew power, not that a relay merely clicked. “Pump on, no current” is a real failure you’ll hear about.
Dry-run protection — no flow or a current signature that says the pump is cavitating? Shut it down before it burns out.
Logs every cycle — run time, current, and starts-per-day to your hub, so a pump heading for failure shows up as a trend.

Pairs well with

Tank level and Water Trough — the level that drives the pump.
Water Flow & Pressure — confirms water is actually moving, not just that the motor spun.
Power Management — run on solar surplus instead of grid or generator.
Bell — a failed pump rings the homestead.
