Released ha-mqtt-discoverable 0.12.0 ...

I ran into a weird Home Assistant scripts issue when I upgraded to 2023.11 from 2023.06 (I know, but I didn’t need the new features and had higher priority stuff to deal with) last week. After the update, when I went to add or edit a script, I started seeing 500s. After some messing around, I eventually moved the couple scripts I had from scripts.yaml as inline scripts in configuration.yaml, restarted, and when I went to edit them, HA offered to migrate them into scripts.yaml. Annoyingly, then when I went to create a new script, HA didn’t return 500s, but the new script didn’t show up in the script list either. I could see it in scripts.yaml, though, and configuration.yaml had the expected script: !include scripts.yaml line in it. ...

In the next few posts, I’m going to document how to set up Home Assistant (HA) from scratch. We’re going to want to protect the admin UI interfaces for HA and its support services with SSL, and add authentication to services that don’t provide it themselves.

Before I start writing more Home Assitant articles, let’s set up a SSL proxy server to keep everything secure. ...

We’re doing a kitchen & bathrooms renovation, and the construction is generating a lot of dust, to the point that I was changing the HVAC filter twice a week. I wanted to see just how much garbage is in the air, so I started looking around for air quality sensors. Naturally I wanted one that I could integrate into my Home Assistant so I could generate notifications if the air was extra filthy. ...
