Reminders for me, you and your friends how to do stuff you need when dealing with microcontrollers like Picos, D1 minis and Raspberry family members.
I have a talent to forget to cover my car before a night with temperature below zero and the next morning I have to scratch away all the ice. As I really don’t like that I decided to build a warning mechanism for that. I already had a Node-RED flow querying the weather API to…
Precondition: Have your lokal MQTT broker and Node-RED installed and setup or access to a remote one. I recently added a http request node querying a weather API to Node-RED. After extracting, the current temperature is then published on the local MQTT and can be used by all devices connected to the broker.In this example…
I like to use the “other view” feature of Notepad++ to show two files side by side. As I often have compare them I really like the synchronized vertical scrolling option which scrolls them both at the same time. There’s an icon you can click, but I prefer to use a key binding to toggle…
It’s a little hidden imo, so future-me or for your service – the setting to show the line numbers.
Most of my Raspberry Pis run headless (just remote console, no GUI). To remind myself and for your service I wrote this short memo how to set them up correctly. You can also find the same and much more Pi related information here, but I like to keep the stuff I need together in one…
As I really prefer Python for my little projects over C++, I flashed my Wemos boards with Micropython and wanted to share how I did it (it was pretty easy). You have to connect your board with USB to your computer, have Thonny installed and the desired micropython image downloaded. (You can do it with…
After expermienting alot with my MQTT server it was pretty polluted with sustained messages and I wanted to get rid of them. The fastest way I got this reliably to work was by deleting the persistence file while the MQTT server was offline. You could delete all or specific topics with a script, too, but…
This is a step by step reminder how to get your Python scripts run automatically on your Raspberry. We will be creating a cron job that is run once when booting. (This should be possible like this or pretty similar on every Linux distribution where Cron is available and is not limited to Python scripts…
