Fronius
Monitors Fronius Symo and Primo inverters via Modbus TCP
Monitor all your installations remotely. Detect problems before your customer calls.

You install heat pumps, HVAC systems or other equipment. After handover, you have no visibility into how they are running. You only hear about a problem when your customer calls. Then you have to drive out. Often for something you could have spotted remotely.
Meanwhile, you are working with four different manufacturer portals. Every brand has its own login, its own app, its own interface. And for devices without a manufacturer portal, you have nothing at all.

You place the ModbusCloud Gateway next to any Modbus device. It automatically reads data and sends it to your dashboard. There you can see all your installations at a glance. You receive a notification when something goes wrong. You can check in remotely. And you don't have to drive out for it.

Connect the gateway to your Modbus device via RS485 cable or the network. Power it via DC 9-30V. LEDs on? The gateway is ready.
Scan the QR code on the gateway or open the local address in your browser. Choose your protocol, select your device from 424 templates, and connect to the internet.
Enter the serial number at portal.modbuscloud.com. Your installation appears instantly. Live data, alerts, historical trends, all in one dashboard.
The ModbusCloud Gateway combines the best of both worlds: the affordability of a compact gateway with the features of an enterprise platform.

Three ways ModbusCloud grows your business. Without extra staff.
Offer your customer an Active Monitoring subscription: 'We monitor your installation 24/7 remotely.' Your customer pays you monthly. You pay the portal subscription to ModbusCloud. The difference is your margin, from day 1.
Your calculation
€ 1.510/year
recurring margin
You set the price based on the value of the installation. Monitoring a €60,000 installation for €50/month is a fraction of what an undetected fault can cost. Your customer gets an immediate alert when values go out of range, before the system breaks down, before consequential damage occurs.

Alert: heat pump system pressure too low
You see in your dashboard that an installation is showing an error code. You call the customer before they notice. You send a technician and schedule a service visit. Billable. Planned. Without the customer having to call you first.
Without monitoring you miss these faults. The customer only notices when it's too late, and you could have sent a technician. With ModbusCloud you detect problems early and schedule more service visits. Those are extra billable hours you would have otherwise missed.
You're quoting alongside two or three competitors. The customer doesn't just compare on price, service matters. You can offer something the others can't: proactive monitoring and remote service after installation.
You don't just monitor | you can also intervene remotely: adjust setpoints, reset devices, read error codes. Without sending a technician. This lowers service costs and increases customer satisfaction.
