Control Relays via LoRa & Ethernet with iNut: Switch Devices On/Off Remotely, Up to Kilometers Away

In many factories, pump stations, irrigation areas, or farms, switching equipment on and off still means walking all the way there to flip a breaker. The pump station is a kilometer from the control room, the electrical cabinet sits at the far end of the field, the fan is up on the barn roof — every action is another trip, and every forgotten shutdown is a night of wasted power or a pump running dry. Running signal wires is costly, prone to breaks, and vulnerable to lightning; doing it manually is always a step behind, with no proof the device actually switched on or off.

iNut solves exactly that bottleneck: a control relay sits right at the device, the signal travels wirelessly over LoRa for kilometers through obstacles, or connects via Ethernet/WiFi inside the plant; everything feeds into iNut PC at the edge layer to run logic, compare thresholds, and raise alerts, then displays on the iNut Platform dashboard and the iNut app. You switch devices on/off remotely, the system auto-switches based on conditions, and you always know exactly what state each device is in.

To control correctly, you first need to "see" correctly. At each point, iNut reads sensor signals (water level, pressure, temperature, current, flow rate) and the device's contact status through digital inputs or Modbus RS485. That way, every on/off command comes with a real response: whether the pump is running or stopped, whether the valve is fully open, whether the cabinet is reporting a fault.

This is the core of it. For scattered outdoor points — a pump station at the end of a canal, an irrigation cabinet in the middle of a field, a float sensor on a pond — LoRa carries control signals and data up to kilometers away, through walls and tree canopy, with ultra-low power consumption that runs well on solar power. Inside a plant with existing network infrastructure, use Ethernet / WiFi Mesh for low latency and stability. Both feed into a single iNut gateway, then uplink over 4G when reaching the Internet is needed.

Instead of watching and flipping switches by hand, you set the rules once: water level drops low → turn on the pump, tank full → shut off; temperature exceeds threshold → run the fan; overcurrent → cut power for protection. The logic runs right on iNut PC at the edge layer, so it keeps working even without Internet, and the relay reports its status so you know the command was executed.

Remote control only gives you peace of mind when you're notified the moment something's off. iNut PC monitors continuously and pushes alerts via Email/Telegram when: a value exceeds threshold, a relay doesn't respond correctly to a command, a device loses connection, or a LoRa node has weak signal or low battery. You can act before a tank runs dry, a motor burns out, or a batch is ruined — instead of finding out too late.

Every control point appears on the iNut Platform SCADA dashboard (self-hosted cloud) and the iNut app: view values in real time, see the on/off status of each relay, review action history and trend charts. You switch devices on/off remotely with a single tap, adjust thresholds right on your phone, and every change is logged for full traceability.

Out at a pump station, by a pond, or on a hillside — places with no grid power and no way to run cables — iNut's LoRa nodes still thrive on solar power and low-power wireless transmission. Install once: the relay switches locally, data flows back to the center automatically, and you can control it from anywhere with just your phone.
