Thread: the tech we can’t use or teach
There’s quite a few ways to mess around with home automation, with the most popular communication methods being things like ZigBee, plain Wi-Fi, and so on. One of the more promising new technologies is Thread, and Dennis Schubert decided to try and use it for a new homebrew project he was working on. After diving into the legalese of the matter, though, he discovered that Thread is a complete non-starter due to excessive mandatory membership fees without any exceptions for non-commercial use.
To summarize: if you’re a hobbyist without access to some serious throwaway money to join the Thread Group, there is no way to use Thread legally – the license does not include an exception for non-commercial uses. If you’re like me and want to write a series of blog posts about how Thread works, there’s also no legal way.
A commercial membership program for technology stacks like Thread isn’t new; it’s somewhat common in that space. Same with requiring certifications for your commercial products if you want to use a logo like the “Works with Thread” banner. And that’s fine with me. If you’re selling a commercial electronics product, you have to go through many certification processes anyway, so that seems fair. But having a blanket ban on implementations, even for non-commercial projects, is absolutely bonkers. This means that no hobbyist should ever get close to it, and that means that the next generation of electrical engineers and decision-makers don’t get to play around with the tech before they enter the industry. But of course, that doesn’t really matter to the Thread Group: their members list includes companies like Apple, Google, Amazon, Nordic, NXP, and Qualcomm – they can just force Thread into being successful by making sure it’s shipped in the most popular “home hubs”. So it’s just us that get screwed over.
Anyway, if you planned to look at Thread… well, don’t. You’re not allowed to use it.

So you can buy Thread dev kits to create your own devices at home, but even such non-commercial use is not allowed. The situation would be even more complex for anyone trying to sell a small batch of fun devices using Thread, because they’d first have to fork over the exorbitant yearly membership fee. What this means is that Thread is a complete non-starter for anyone but an established name, which is probably exactly why the big names are pushing it so hard.
They want to control our home automation just as much as everything else, and it seems like Thread is their foot in the door. Be advised.
