It is prime day and you are wondering which kettlebells to buy? What are the possible weight combinations of all different weights including using between one and all of them with a dip belt? Yeah that’s really the motivation of how this started 🙂 What became of if was a method taking multiple int values,…
A small script to scan the neighbouring Wifis with your microcontroller. You get the following information about them: Kept the code as simple and small as possible. Available functions in network package could vary depending on used microcontroller type and micropython version / implementation. Resource links:
Not everything is like shorts for computer science students – some other things only make sense in certain months. Like my webscrapers for the current water temperature of the outside pool or the warning system for below 0°C degress. To hide them in the HomeAssistant UI I created a helper that is filled with the…
I currently had the problem of handling updates with partial settings of RGB lights through MQTT and HomeAssistant. As The setting has to be complete at all times in the running system, so my first solution were multiple if else clauses and changed flags. It works, but it is ugly and over-complicated. I didn’t use…
Generally speaking this is how I learned to cache a JSON object in a Node-RED flow with the Change node by setting a flow based variable. Specifically this handles a problem with HomeAssistants light card backed by a MQTT light (defined in the configuration.yaml) only emitting partial values of the light setting when updating. New…
Be it HomeAssistant, mosqitto, NodeRed – I use docker to run them on a Raspberry and thanks to Portainer I can manage them with a a nice WebUI. It has been some time I set it up and as needed it again and had forgotten some of it I decided to make a short todo…
Plain and simple (or better in the case I forget it again). You can add the device when pulling and starting the HomeAssistant container. Make sure to adapt config path to yours.Add “–device/dev/NameOfDevice” If you don’t know the path of the USB device you can see a list of them with this command: I a…
A milltion times already on the internet and sorting methods already integrated in the language – so why?Because written things stay better in the brain and I like to understand things from the ground. ArjanCodes (I love your content!) recently posted a video about recursive functions and used a similar code. I won’t have written…
FTP to your WordPress root directory and delete the “.maintenance” file. This is only the simple solution for the case you closed the browser tab you started the update in and now the banner “…in maintenance mode” appears instead of the website.This won’t repair your wordpress installation when something went wrong with it and that…
For a container class with a dictionary with config values (among other members) I wanted easy reading access as if it was a dict itself. For that you only have to implement the __getitem__ method. You can extend the provided dict functionality for your class if needed like the following: All but the update method…
As most of the time – there are multiple valid ways of doing it. Keeping the order I prefer easy and readable, if it is not crucial for performance to go another way.Create a new list and add only values to it that are not already included. You can do this with a simple list…
Yeah I know it’s kinda pointless. I was thinking the same thing when I doomscrolled youtube shorts watching a so called programmer “Herr Programmierer” showing a simple script moving the mouse in a fixed interval to coordinates in a fixed square. I was bored, I like Python and sure I could create a better pointless…
