Installing the BAYROL Automatic Cl-pH in the Pool and Retrofitting a Temperature Sensor: My Experience
Having crystal-clear pool water shouldn’t depend on whether I have the time or inclination to read test strips and adjust the water levels manually. That’s exactly why I upgraded my pool system with an automatic dosing system and installed the BAYROL Automatic Cl-pH. The system continuously measures the pH and redox values and can dispense chlorine and pH adjusters as needed. In a second step, I retrofitted a BAYROL temperature sensor. This allows me to check not only the water parameters but also the current water temperature via the display, the web portal, and the app. In this field report, I document the installation and commissioning of Automatic Cl-pH, explain…

Installing Air Conditioning Yourself in an Older Building – Heating and Cooling in Practice
Installing a split-system air conditioner yourself in an older building—does that really work? It was precisely this question that I explored in an Art Nouveau villa dating from 1900. In this field report, I document the entire installation process for a split-system air conditioner, explain the technology behind the air-to-air heat pump, and demonstrate why modern air conditioners today—

Robot lawn mower without boundary wire in test: LiDAR vs RTK in comparison (ANTHBOT M5 vs M9)
Robot mowers without boundary wires are currently one of the most exciting developments in the gardening sector. In my test, I directly compared two different concepts: the ANTHBOT M5 as a LiDAR robotic lawnmower and the ANTHBOT M9 as an RTK robotic lawnmower with GPS navigation. Both models manage completely without a perimeter wire and show in the practical test how well cordless robotic lawn mowers really work today. In this comparison, I share my experiences from my own garden, discuss navigation, obstacle detection, edge cutting and set-up and clarify which robotic lawnmower without a wire is the best choice for which area of application.

Lymow One Plus in test: RTK robot mower for large areas & difficult terrain
In the Lymow One Plus test, I show how this robotic lawnmower performs in practice without a boundary wire on a large and demanding area. With RTK navigation, chain drive, 45° incline and a cutting width of 40 cm, the Lymow takes a significantly different approach to classic robotic mowers. I tested the new Lymow One Plus extensively and compared it directly with the Lymow One. The focus is on performance, navigation, off-road capability and the question of whether this system is really worthwhile for large plots of land. The article provides a detailed insight into the technology, set-up, practical test and my experiences – including strengths, weaknesses and a…

The best Reolink 4k PTZ surveillance cameras in comparison: 823S2 vs 823S1 vs TrackMix vs TrackFlex in test
For me, Reolink is one of the most exciting manufacturers of modern 4K PTZ surveillance cameras for indoor and outdoor use. In this Reolink surveillance camera comparison, I analyze several high-performance models – from classic PTZ cameras with optical zoom to dual-lens and floodlight variants for outdoor use. The focus is on image quality, motion detection, night vision, PoE vs. WLAN, local storage without a subscription and the question of which camera is really suitable for large properties, driveways or security-relevant areas. I will show you my practical experience with the RLC-823S2, RLC-823S1, TrackMix and TrackFlex and categorize the models technically and strategically. The aim of this article is to…

Expand Reolink NVR storage space – Installing and configuring hard disks correctly
In this article, I will give a structured overview of the Reolink NVR models – maximum hard disk size and storage capacity and show what really matters when choosing the right HDD. A Reolink NVR is the central element of a camera surveillance system – and the storage strategy determines how long recordings remain available and how stable the system runs. I go into detail about the differences between RLN36, RLN16-410, RLN8-410 and RLN12W, explain the maximum hard disk size per model, show the correct choice of surveillance HDD and document the complete installation including formatting and storage management. I also explain how an NVR works with multiple HDDs and…
