The Basics of Modbus Monitoring with PRTG Network Monitor (With Custom Sensor Script)
Article explains how Modbus/TCP works and shows how to monitor Modbus/TCP enabled devices with PRTG Network Monitor
The Modbus protocol has been around forever (since 1979 to be exact) and is used by many industrial systems, but also energy systems like heat pumps and solar converters. Initially it was used via serial communications, then – in 2007 – a TCP based version was created that communicates via TCP, usually using port 502.
The following article explains how Modbus/TCP works and shows how I can monitor Modbus/TCP enabled devices with PRTG Network Monitor using a simple PowerShell script.
I wish I could share a one-size-fits-all script that just works for most people. But unfortunately this task usually requires some hacking and coding…

We have solar panels on our roof which are able to generate a peak power of 10 kW. An energy controller controls the converter, our heat pump and our battery with the goal that most of the solar energy is used locally. First we use the solar energy in our home, we charge the 230V-battery, and we load the heat storage tank. Only if even more solar power is generated we send the rest into the grid.
To visualize this and I am monitoring this system with PRTG using the Modbus protocol.

A low-cost, always-on mini dashboard on my desk
On my working desk I wanted to have an always-on screen with the current status of the systems and KPIs that I am monitoring all the time. Of course I did not want to run a PC all the time, so I needed something “lighter”.
I also wanted something made from out-of-the-box systems, not an arduino system that I would need to solder together with the risk of hurting myself.
In this post I will share how I created my little desktop dashboard for around €350.
Müssen Internet-gesteuerte Glühbirnen wirklich sein…?
Ich hab’ sowas nicht. Und ich weiß warum… Dieser Vortrag erklärt es ganz gut!
