Trust HOMEr

It's not really surprising that smart speakers can be a gateway into your own four walls, exploited by people who don't really belong there. We tried to find a solution for this on Maker Monday.

Monitoring Certificates and Availability of Devices

Video release day is a happy day for us. And today we are happy to the power of two. Below you find two educational and insightful videos.

Join the public BETA of BitDecoder - Easy translation of IoT data into visual formats

If you are a regular reader of our blog, you have most likely already read about BitDecoder. The foundation of BitDecoder is our partnership with Sigfox, a provider of a global IoT network using low-power wide-area network (LPWAN) technology. Sigfox technology is embedded in license-free radio modules that enable objects to connect to that global IoT network. The idea behind the partnership is to use PRTG Network Monitor to monitor data from Sigfox-ready devices.

Processing of Personal Data by Companies: 5 Things to Keep in Mind

You work in the IT department of a reasonably large company. Good for you! Wait... What was that? You are also responsible for processing and maintaining personal data of customers, partners and employees? Well... 🤦‍♂️

Really Understanding MQTT

MQTT is as sexy as it sounds. It's an open OASIS and ISO standard lightweight, publish-subscribe network protocol that transports messages between devices. The protocol usually runs over TCP/IP - however, any network protocol that provides ordered, bi-directional connections can support MQTT.

How to Use the New WMI Battery Sensor of PRTG

Is your PRTG installation already up to date? If not, that's a bummer, because in this case, you won't be able to enjoy the new WMI Battery sensor that we introduced with the 19.3.52 release.

Monitoring a Terrarium With PRTG

This is Merlin, a 6-year-old corn snake. He lives in a terrarium in a home in Switzerland, where he's taken care of by Patrick and his wife. Generally, even though corn snakes are relatively easy to care for (making them ideal pet snakes), Patrick—being an electrical engineer—had a compulsion to do something geeky with the terrarium. He eventually decided on measuring the temperature and humidity in the terrarium remotely. Here's the story of how he came up with a solution involving PRTG Network Monitor.

A Tesla Potentially Equals a CCTV System on 4 Wheels: New Open Source Project Is Dynamite

We already had a hunch that CCTV in the cities of tomorrow could be used to cause social distress among citizens, and this theme triggers the primal fears of many people. However, in this discussion, which is also a recurring theme in the context of Smart City and IoT, little has been said so far about electromobility. Electric cars are usually products of the most advanced technology, which includes the recording and evaluation of immediate environmental data. The folks at, a German tech news site, recently presented an open source project that really deserves a closer look.

And now we're back with season two, and we have more projects to show you! In the first episode, we show you how we created a connected start/finish line (that also counts laps) for the slot car track we recently built through our offices.

What I Learned About Agile By Building A Giant Carrera Racing Track

Here I stand, with duct tape in my hand, trying to fix an insane series of 39 loops of a giant Carrera slot car racing track. I screwed up, nothing works and time’s running out. I used to think that I’m better than a third-class hotfixer. But wait – I probably should start my story at the beginning:
