A machinery manufacturer has 80 pieces of equipment deployed at its customers' sites. Each preventive maintenance visit requires a 2- to 6-hour trip. The annual maintenance cost exceeds €300,000 for travel alone.

Eziwan sets up a permanent OpenVPN/IPSec VPN connection on each machine. Technicians remotely access the HMIs, Siemens S7 and Schneider M340 PLCs, and RS485/Modbus data. Automatic alerts on KPIs (temperature, pressure, cycles) enable proactive predictive maintenance.

"Before Eziwan, every machine alarm required us to go out on-site. Now we can diagnose the problem in 5 minutes right from the office."

A network operator manages 200 electrical substations using obsolete 2G/3G GPRS modules. The 2G network is being phased out, and frequent disconnections are degrading the quality of remote meter reading. The transition to a modern solution is urgent.

Eziwan is replacing GPRS modems with the Eziwan LTE Gateway with Dual SIM. Modbus TCP/RTU data collection from meters and inverters is supported natively. Data is sent to InfluxDB every 15 minutes via MQTT. SIM failover ensures continuity even in the event of a carrier outage.

"The migration of our 200 substations to LTE was completed in three months. Eziwan's ZTP saved us from having to make hundreds of on-site visits."

A network of 60 stores relies on an ADSL or fiber connection for point-of-sale systems, digital signage, and cash register monitoring. Each outage results in an average loss of €800 in revenue and requires the emergency response of an IT team.

The Eziwan router is installed in failover mode behind the main switch. In the event of an ADSL or fiber outage, the system switches to 4G in less than 30 seconds. Centralized monitoring provides a real-time view of the status of each location. Alerts notify the store manager before they even realize there’s a problem.

"Since switching to Eziwan, internet outages no longer cost us anything. The transition to 4G is seamless for our in-store teams."

A 300-hectare vineyard wants to monitor its soil moisture sensors, weather stations, and irrigation valves. The plots are scattered over 15 km, with no wired network infrastructure. LoRa technology has limited range in certain areas.

Eziwan deploys LTE routers powered by 12V DC from solar panels. RS485 sensors and Modbus RTU valves are connected directly. Data is sent to an MQTT broker every 5 minutes. Threshold alerts automatically trigger irrigation or notify the operator.

"We connected 15 plots in one week. Soil data is updated every 5 minutes—we've reduced our water consumption by 18%."

A regional carrier wants to connect its 40 trucks and 8 depots to centralize the management of shipping orders, monitor cargo temperatures, and remotely access dock cameras.

Eziwan equips each vehicle with an LTE router featuring dual SIM cards to enable failover between carriers depending on geographic location. The depots have backup LTE connectivity. A centralized dashboard monitors the entire fleet, providing alerts regarding connectivity and sensor events.

"We now manage 40 trucks and 8 depots through a single portal. Drivers no longer need to call if there's a problem—we see it before they do."

A local government agency manages 35 drinking water pumping stations scattered throughout rural areas. The equipment has no connectivity, and malfunctions are detected only during weekly inspections. An undetected pump trip can result in a water outage for several municipalities.

Eziwan deploys LTE connectivity with a 99.9% SLA at each station. Schneider pump controllers communicate via Modbus RTU. Tank levels, pressures, and pump statuses are reported in real time. SMS and email alerts are sent within 2 minutes in the event of a fault.

"We used to discover a pump failure during our Friday rounds. Now we get an alert within two minutes—we can take action before the outage."
