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…
Yeah we all can loop, but can you any or all? Checking if condition matches for at least one element of an iterable (e.g. list, tuple, set) In Python you can write that nicer with the builtin method any(): But who doesn’t like a one-liner (that is understandable): Very similar is the case if you…
I wanted to know which topics are active on my MQTT server and if there were some skeletons in the closet I could get rid of. Many Iot devices, Node-RED flows and surely some unused topics or old retained topics lead to more or less MQTT being a chaotic museum of topics. This is just…
Pressing F5 does not refresh your view anymore but rewinds the current media?F11 does not run the selected JUnit test in Eclipse any more but activates Caps Lock? I have a Logitech K850 keyboard and I unintentionally turned on the function key lock (didn’t even know such a thing existed). Try the following: [Fn] +…
This covers a very configurable and more complex variant of measuring brightness and turning on LEDs.If you are looking for a more basic variant: It all began with a LDR and curiosity. The result is a night light for a ESP8266 like D1 Mini or Raspberry Pi Pico (W) which compensates darkness with many configurable…
Externalizing the configuration is a good idea. This makes the reusability of your program much higher and a user doesn’t have (and shouldn’t have to) change values in the code.This separation tends to show where your code is perhaps too tightly coupled and constants are referenced directly as they are directly available in the script…
