Today thousands of students of the Fridays-for-Future movement are on strike. They protest for more aggressive action against climate change. Formally I am not a student anymore, but I consider myself a life-long learner and student of life as well. So here is my student-contribution for global awareness of the CO₂ crisis.Continue reading “My Fridays-for-Future project: Monitoring the CO₂ in the atmosphere to stay aware of Earth’s most important metric”
With PRTG I can do “live” monitoring of things, e.g. environmental stuff like the current sunlight (solar panels), my heating system and temperatures throughout the building. I also wanted to add a look into the future so I looked around for a html widget to display the weather outlook that I could add to my PRTG maps.Continue reading “This is my favorite free weather outlook widget for my dashboards”
Every other night we forgot to close our garage door in the evening and it stayed open all night. Obviously we needed a door monitoring that alerts us whenever the door was left open after 20:00. There were just two tiny problems: There was no close-by power outlet or ethernet port and the steel enforced concrete structure of our garage shielded off our home wifi networks.
In this article I will describe a solution which is based on the Sigfox IoT wireless network and PRTG which I use to monitor our home.Continue reading “How I monitor my garage door for €69 (and without access to power and wifi)”
The power saving feature “connected standby” of Windows 10 causes PCs to go offline from Teamviewer, so you can’t wake them up and connect/control them. But there is a trick that stops this behavior.Continue reading “What to do when Teamviewer goes offline as the PC goes into “connected standby” mode”
In this article I will show how to monitor all available wifi networks (SSIDs) and their signal strength using PRTG.Continue reading “How to Monitor all available Wifi Networks and their Signal Strengths with PRTG (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…Continue reading “The Basics of Modbus Monitoring with PRTG Network Monitor (With Custom Sensor Script)”
