All things me.

Thing’s to keep in mind when migrating an IKEA TRÅDFRI setup to Home Assistant

posted this note on and tagged it with Home Assistant Smart Home

This is a continuation of my recent post about migrating my TRÅDFRI stuff to Home Assistant. As I wrote in that one, it’s important to note that you will be forced to factory reset all your bulbs, switches, dimmers, etc. meaning all your settings will be wiped. It is annoying to redo all settings and all labels in Home Assistant but it’s not in any way impossible.

What is worth noting, and potentially very complicated, is how you factory reset them.

TRÅDFRI short cut button

To reset this button, unscrew the back of it and push the button next to the Bluetooth pairing symbol four times. So far I’ve connected one such button to Home Assistant and it worked without any complications.

Lightbulbs

The TRÅDFRI bulbs needs to be turned off and on five times in quick succession. So far, also not a problem for me.

LED Drivers

Here is where I’m running into trouble. To reset the LED Drivers I need to press a small button on the driver itself, using for instance a paper clip. It is by no means hard to do, but a couple of my drivers are wall-mounted behind cabinets, meaning I have a stimulating afternoon ahead of me.

Today, almost a year after I purchased a Home Assistant Green, I’m finally committing and moving all my Ikea TRÅDFRI smart home stuff from Ikea’s own gateway directly to Home Assistant using ZBT-2 as the Zigbee antenna/gateway. So far many things work as planned, others are more involving.

The main issue to be aware of if you are going this route is that you can not transfer settings from the IKEA Smart Home app to Home Assistant. The only way, as far as I know, to make this transition is to factory reset every single TRÅDFRI gizmo in your house and pair them with Home Assistant, re-labeling, resetting, making new scenes, etc. I was more or less counting on that so I have set the whole day aside for this.

Poster from "From" Earlier this week Linn and I finally managed to stay awake after the kids had been put to bed, and we watched the first episode of the latest season of From. It is by no means a great tv show in any sense of the word, but we really like it. The premise is interesting and it manages to keep things exciting over time.

Clearly it is not an expensive ”prestige tv show”, it’s more like low budget schlock, but that doesn’t bother me. Back in the day, tv was low budget and schlocky. The great shows of the 90s, like The X-files or Twin Peaks for instance, occasionally looked like crap, had meandering episodes, ”mythology” episodes that contradicted each other and so on and so forth. Yet they were entertaining.

Dune

posted this note on and tagged it with Books Denis Villeneuve Dune Movies

Movie poster for Dune A few months ago I started listening to ”Dune” as an audiobook. I found it interesting but once I stopped listening for a while I found it hard to press play again, either later the same day or some other day. It is probably one of those books that I would have loved if I had gotten into it in my teenage years. Maybe the problem is me and my attention span, broken by the modern world. Or maybe the novel is just to bloated. Or maybe both.

Either way, I sort of left it behind and instead gave the Denis Villeneuve movie a go. I’ve not watched a lot of Villeneuve movies, but it think Arrival is one of the greatest movies ever made. I’m less thrilled about Dune.

Don’t get me wrong, it’s not a bad movie in any way, shape or form. On the contrary, it’s probably a great movie in most ways. It’s stunningly beautiful and the music is Hans Zimmer being his most Hans Zimmer. But I feel detached from it when I watch it.

My main problem with it is probably that it is so ”serious” all the time. Maybe I’m broken by Marvel movies, and at least in theory I believe that there are too many quips and gags in way too many movies, but maybe the opposite with zero percent levity is sort of an over-correction. Everybody is so serious in the movie, all the time. Everything is grim. Macho men speaking in orcish sounding languages being macho.

As I’m writing this I realize that it sounds like I hated it, but I really didn’t. It is a good movie and I would absolutely recommend it. But either it lacked something, or I currently lack something to appreciate it the way it deserves.

Got tipsy and went down several YouTube rabbit holes. From Nick Cave & Kylie Minogue to Miley Cyrus, to Taylor Momsen fronting Soundgarden to a whole bunch of Ozzy tributes.

How did I miss that Jenny from Gossip Girl can rip through ”Rusty Cage”?

Why haven’t I noticed that Chad Smith is a fantastic drummer?

Jack Black and Ozzy sitting off to the side, singing along, is probably the most heart warming thing I’ve ever seen.

I don’t know what it is about Dave Growl, but he is something different when it comes to drumming.

Miley is the greatest ccm vocalist of my generation!

In an earlier post today I made a reference to the ”Tears in rain” monologue from Blade Runner which, naturally, lead me to its Wikipedia page and had me reading it to myself multiple times, hearing Rutger Hauer’s voice in my head. In doing so, I made a connection to a post about Pluribus for a few weeks ago where I argued that creation was the one thing the hive-mind, a stand-in for generative AI, couldn’t do. Viewed through a certain lens, Roy Batty shows his humanity – not only in showing compassion but also – in actually creating. He used his last breaths to create a poem.

An old post by Dave Winer that still rings true, uncomfortably true

posted this note on and tagged it with AI Dave Winer

If you programmers still don’t want users running servers, then I propose you look at your thinking a bit, and wonder if you’re perhaps a member of the computing ”priesthood,” trying to protect what you do from the unwashed masses? If so, you’re on the wrong side of history, imho. The inexorable process of tech is taking things you used to need to be a wizard to do, and making them easy for normal people.

Dave Winer – ”Fascinating thread on Twitter”

The link to the original Twitter thread is broken so the full original context is sort of lost in time1 but regardless of the specific issue (servers, apparently) this quote feels apt for the current moment of AI, vibe coding, etc. Uncomfortably so because I feel uneasy about so much of the whole AI thing but maybe that is because I’m part of ”the computing ’priesthood'”.

In the world of Pluribus, creative work is a monumental event

posted this note on and tagged it with AI Creative work Pluribus

A quick thought on Pluribus. From what I understand it’s been conceived over many years, meaning it was not originally intended to be about generative AI. However it most certainly became partially about that. One scene that feels like a commentary on genAI is the scene where Carol has started writing again and how delighted Zosia is.

Now, it is possible that it’s just another case of the collective ”yes and”-ing Carol, but I feel like it’s something more than that. It seems like the collective, like genAI, can’t create anything. They’ve already consumed all the worlds stories but they can’t add create any new ones. Therefore, in the world of Pluribus, Carol creating is a monumental event.
