Going Further with Home Automations in Node-Red

In my last post about using Node-Red to make automations with Home Assistant, I showed some very simple flows for turning lights on and off. While it is important to get used to the Node-Red way of doing things and it’s interface, none of the examples in my post are very compelling. All of that can easily be accomplished in Home Assistant already, so what makes Node-Red so awesome?

Let’s examine some of Node-Red’s features a little closer to get a better idea of what’s going on, how we can use that to create dynamic automations with Home Assistant, and an example of an alarm clock radio flow that uses some advanced logic nodes.

Useful Sensor: Cardinal Wind Direction for Home Assistant

At a glance – gustier than usual this morning.

As someone who cycles to work most days, I keep a pretty close eye on the weather.

Home Assistant has a ton of weather platforms – and the Dark Sky one that I prefer tracks wind direction. The only problem is it returns the direction in degrees, which is meaningless to me.

Self Hosting: Setting up a Personal Wiki with DokuWiki

One of the most useful things I self host on my server is a personal wiki. I use it for note taking on projects, a journal, a beer homebrew log, storing recipes, config files, and for archiving web pages or documents. It is a great alternative to Evernote or OneNote if you want to keep your information out of the corporate cloud.

There are many wikis out there but I prefer the low-overhead DokuWiki, which is easy to install and uses flat plaintext files to store your wiki pages so it’s easy to set up anywhere and backup your data. DokuWiki as a default install is very basic and can be extended to do almost anything with a few plugins. Read below for some of my recommendations for making the most of your wiki and some example use cases.
