HA Automation: missing step details (traces)
When using multiple if-conditions, the traces are difficult to interpret as there is no indication of the condition or its entities: Although the step details show the result of the queries, they only provide an indication of which condition led to the result by means of internal numbering: ... continue reading
Cura in version 5.8.1 published
I have used 2 different slicers extensively so far: Cura and PrusaSlicer. Both slicers are free, both deliver usable results with the manufacturer's default settings, both have their strengths and hardly any weaknesses. ... continue reading

OpenWRT WLAN FT configuration - Online generator
To be able to set my WLAN settings for OpenWrt more quickly, I have put together an online wizard for creating the necessary commands. The aim of the setup is to create a common WLAN mobility domain for several access points: so that roaming - FT (Fast Transition) - between the access points works properly. Access points with an existing 2.4 GHz and 5 GHz band are required as hardware. The commands are compiled for the first two WLAN interfaces to enable band steering between the two interfaces.... ... continue reading
OpenWrt: generate External R0 and R1 Key Holder - online
Create OpenWRT 802.11r External Key Holder List: r0kh and r1kh For a simpler setup, it is usually recommended to use the "Generate PMK locally" option, as this allows OpenWRT to generate the keys itself, at least for WPA2. Alternatively, the key lists can also be entered directly in the GUI or specified via the config file. To make it easy to sum the keys, I have built a form that can be used to generate the necessary settings. ... continue reading
MPP Bypass Diode Power Optimizer vs Dynamic Peak
Each PV module has a so-called Maximum Power Point (MPP), the operating point at which the voltage used achieves maximum output. The data of the modules can be found in their data sheet. ... continue reading
PV - Considerations - Planning - Implementation
Compared to 2023, the module prices are now much cheaper and the waiting time for implementation much shorter. This was actually foreseeable, but I - like many others - lost my nerve in 2023 and installed the PV system on the roof myself. In hindsight, I was able to compensate for the higher material price with my own work and the more expensive - but more lucrative - subsidy. And: I can still feed the entire output into the grid before the nearby transformer station is extended, even if the rem... ... continue reading
OpenWrt Practice: WLAN access point commissioning
This article is about WLAN: everywhere in the house: on every floor, specifically about the commissioning of WLAN access points with OpenWrt as firmware. I have chosen the ZyXEL NWA50AX as the hardware for the access points: Equipped with 2 CPU cores, 128 MB flash and 256 MB RAM, the NWA50AX supports WiFi 6 (802.11ax) and can be powered with the supplied power supply unit or optionally via PoE. The ZyXEL NWA50AX is one of several available devices on which OpenWrt can be installed, see: OpenWrt... ... continue reading
The best AntiVirus? Is Windows Defender enough antivirus?
In times before Windows 10, the use of an own AntiVirus program was necessary to run the PC reasonably safe. Initially, Microsoft did not offer a solution here at all, later, in Windows 7, the Microsoft AV could be installed under the name Microsoft Security Essentials and since Windows 8, an anti-virus protection is integrated in Windows, the "Windows Defender". Windows Defender can be found in the settings under"Virus & threat protection". To make it appear that the firewall works in conju... ... continue reading
