Often-used aliases for common package managers.

Add them to your bashrc/zshrc! Never think about which OS you're currently using!

Usage:

sea some key words

SevDesk is a useful tool, but on my 13" MacBook, I find it wastes too much whitespace on menu elements and such, which makes it hard to keep an overview.

These styles can easily be applied using StyleBot or your CSS-tweaking tool of choice.

Some aspect ratios will look yanky with this applied, so YMMV.

Parsing SML Energy Meter Values for Loxone Miniservers

This is a custom PicoC program to parse the SML energy readings in a tibber+Loxone setup.

Our system runs a [tibber Pulse], connected to a [EMH ED300L][ED300L] energy meter. We run this code on a [Loxone Miniserver][loxone], which can run custom PicoC code.

We use the TCP stream method to read the current SML data packet from the tibber bridge
