Home Assistant ideas

What to do with Home Assistant

Some ideas I might pursue at some point.

Air humidity alert

When air humidity reaches a threshold value, get an alert on my phone.

Make sure to be alerted only once.

Recherche zum Thema Stecker-Solaranlage, Plugin-PV, Plug-and-Play PV, Balkonkraftwerk, you name it

Ziel

Solaranlage an einer Mietwohnung mit großem Balkon in südlicher Ausrichtung anbringen, weniger Strom vom Energieversorger verbrauchen, Geld sparen, Energiewende unterstützen.

Hinweis: Die Informationen trage ich im August 2021 für meinen Wohnort, der im Bereich der Regionetz GmbH Aachen liegt, zusammen.

Offene Fragen

  • Anlage anmelden oder lieber "schwarz" (ohne Anmeldung) betreiben?
  • Was steht in der Norm VDE-AR-N 4105? Diese kann man nur käuflich erwerben.

How to re-partition an external drive from a Mac

WARNING: This erases all data stored on the drive.

I couldn't re-partition a freshly bought USB SSD via the Apple Disk Utility app. With the help of a Stack Overflow thread I came up with this method to create two partitions on the disk.

After this process, the disk can be re-partitioned interactively using Disk Utility.

  1. Plug in the drive to the Computer.
