Also, the URL is a mile long...

There used to be an online competition years ago, I think it was called "TheMostSpam.com" or something like that, where you would get a temporary email address and it would track a leaderboard of whose address received the most messages in 24h, a month, and lifetime. Modern email tech rendered it pointless, but back in the days of the simpler internet, it was a fun concept.

IKEA moves to Thread (and away from Zigbee)

This sort of makes it sound like the advantage of Thread is merely that it's new, and therefore nobody will be affected by having a poor pre-existing Thread setup. If ISPs were sending people Zigbee hubs, it sure would be the cheapest shit available, which could very well translate to similarly terrible Zigbee performance.

I see your point, but there should be much more merit to the specialized IoT protocols than just that nobody has yet flooded the market with terrible Thread/Zigbee devices.

I'm not sure manufacturers choose WiFi because of hardware costs. There are often other reasons (some good, some terrible) for this choice, but I'm certain Zigbee support has to be cheaper; having disassembled plenty of such devices it's almost always a dedicated IC and a tiny PCB trace for an antenna. WiFi support requires a fairly complete TCP/IP stack implementation, basic certificate management etc. which will inevitably require a small SoC; and while prebuilt solutions are plentiful, Zigbee alternatives are an order of magnitude cheaper.

I can imagine software development costs being lower, though, given how every other programmer knows a fair deal about TCP/IP networking, while good comprehension of dedicated IoT protocols is a much rarer skill, there are also much less community resources and open-source solutions available etc.

detcham bahn?

On routes where it switches direction at Kokura station (running between Hakata and Oita using Nippo Main Line and Kagoshima Line) there is a bit of a chaos moment when all passengers stand up to rotate the seats, and stuff they left in the compartments in the seats in front of them (like the mini-pocket) gets flipped to 2 seats behind them.

Right, thanks. But this can be easily resolved by:

  • Removing devices' access to WAN, which also vastly reduces the external actor's ability to compromise them in the first place.
  • Isolating devices from each other with internal firewall rules, allowing them to only interact with the hub host. Is this correct, or am I missing something?
