IKEA moves to Thread (and away from Zigbee)

I am pretty happy with zigbee so far. Is that a good thing? I haven‘t done anything with matter so far.
@arschflugkoerper@feddit.org I have nothing useful to contribute, but I fucking love your username. Thank you for the smirk you gave me, have a nice evening mein Genosse 👋
Tja
thanks lol
I agree, great name!
- Thread and Zigbee use the same physical layer and MAC layer (IEEE 802.15.4), so in most case it can use the same hardware and just with different firmware (if manufacturer want).
There is even a project to run both Zigbee coordinator and Thread border router on the same chip. It works! Although it causes some issue so Home Assistant no longer recommand this "multiprotocol" way, but this is a strong demonstration of the interchangeability between Zigbee and Thread. - Thread Group members is almost the same companies who found Connectivity Standards Alliance (former Zigbee Alliance). When Connected Home over IP (CHIP) project was renamd to Matter at 2019, they create Thread Group to unify the home connectivity: Only use one network layer named IPv6 and one application layer named Matter. Zigbee can't reach this target since it use its own network layer and application layer. So they invent Thread, which still based on IEEE 802.15.4, but with IPv6 as network layer and can transport Matter on it.
- Thread and Zigbee use the same physical layer and MAC layer (IEEE 802.15.4), so in most case it can use the same hardware and just with different firmware (if manufacturer want).
Yeah so far it doesn't matter because zigbee and zwave still work fine.
it doesn't matter
Hehe.
Anyway, I am also completely on Zigbee. While I like the concept of Matter over Thread, I wouldn't want to switch, because it will start with a too small network to cover a good distance and if I start replacing Zigbee devices, I effectively sabotage that network as well. So my only move would be to replace all Zigbee with Matter/Thread devices. And that seems insane. So I hope I keep getting new Zigbee devices for a while.
I am just getting started on this journey but zigbee seems great and I like that it works fine even if the wifi goes down. I'm not sure what the drawbacks are or the benefits of Matter.
matter and thread are different things fyi…
thread uses the same wireless communication as zigbee (zigbee has other stuff on top of it), so is a low power wireless protocol
matter is the data format that devices use to communicate on top of an IP-based network like wifi or thread. it’s meant to standardise all these competing “works with google” “works with alexa” “homekit compatible”: if it works with matter, it should work with any coordinator that has matter compatibility (which all the big ones do these days)
thread will work great if the wifi is down - same as zigbee!
matter also (afaik) forces local devices: your coordinator (a homepod, alexa, etc) talks directly to the device without going through the internet. again, same as zigbee
Thanks for the explainer, that last point is really great actually and I'm surprised that Amazon/Google etc are pushing for Matter if the data isn't sent to the internet.
well your coordinator gets to end whatever it likes wherever it likes but the devices themselves communicate over your internal network so everything should be much snappier
me either, why do we need yet another standard?
All of the major platform holders agreed to come together and interoperate with this one. And like others said, it supports IPv6.
Still yet another standard, but it’s one that’s not controlled by a single vendor. Its setup to be more like WiFi and Bluetooth than any other standard has been in the past. IMO.
and worth noting as well that thread is only kinda another standard: it uses the same wireless communication as zigbee does
And Matter is modeled after HomeKit.
It reminds me of how the MP4 container that became a standard is modeled after the MOV container.
It’s common for standards backed by consortiums to be modeled after something that is already successfully achieving the goals of the system.
