Zigbee is indeed good enough. The issue is that it solves the problem well enough and doesn't allow for maximizing how much customers are milked for. So customers will always choose Zigbee over any other option that also solves the problem plus some useless features, less control, and increased security surface area. There is a very clear signal that is easy to pick up: either you support zigbee in your IoT device or…

IMO Thread has one major benefit over Zigbee: the Thread mesh can extend over Ethernet (via TREL). Zigbee ought to be able to do this too, but I’m not aware of anyone actually doing it. There are a couple of in-progress implementations of Zigbee on a regular computer using Thread radios and the Thread RCP protocol. Maybe one of them will add the ability to use multiple radios.

I think it's a feature to enforce network segregation and have gateways be intentionally chosen. IoT devices are known to be high-risk security. We should shape the solutions such that the minimal energy path is a good one.

Huh?

If I have one building with one automation system but the building is too physically large or has walls that attenuate RF too much or where I don’t want a router node in the middle or where the latency across a mesh is too high, I want to be able to extend the network at low latency by plugging in another network-attached radio base station but without needing to manually pair each device to the closest base station.

Thread does this out of the box. Zigbee does not.

Having been in the business of creating standards compliant equipment in the past, the problem is not as simple as you state. You can provide all of the reference implementations you want and you still will get variances. The state-of-the-art solution is to put a bunch of people on planes and burn a bunch of jet fuel to attend a "test fest". You can't issue interoperability until you do this. This costs money that ne…

> ou can provide all of the reference implementations you want and you still will get variances. A proper reference implementation should first and foremost come with an extensive battery of regression tests, something many a vaunted "standard" utterly fails to provide, being instead tomes upon tomes of impossible to decipher specifications, written - of all things - in human language. Such a battery of regression te…

In practice they never do. There are too many corner cases that people don't think of. It's almost a law of nature that you can't capture the complexity of any non-trivial specification in regression tests.

It is supposedly an open source standard that do not requires internet connection to work, and can use regular wifi (2,4ghz) networks as a means to connect devices so you do not need to buy a hub for them. You can create your own hub with a mini pc for instance with a regular wifi card. No need for specific hardware

No need for specific hardware Meet zigbee2mqtt and ZHA. You only need a cheap USB adapter as a Zigbee coordinator and you are ready to go.

So you need to buy and adapter. With Matter you don't, you can use your regular wifi cards. No new "adapter" needed.

I mean you can already do exactly that with zigbee after buying a zigbee usb connector which are extremely cheap. I know because that’s what I have been doing for the past five years. But to be fair my setup is now mostly IKEA so I guess I could go back to a bridge and stop having to maintain my stuff at some point.

All of this can be done with ZigBee. It is open and local mesh over 2.4ghz.

You need to buy the zigbee adapter. With matter you can use just regular wifi cards

What makes you think you will be able to use Thread with a regular wifi card? That's not my impression.

Matter is just the protocol and Matter over Thread is pretty sure to be prefered by everyone over Matter over Wifi because of the power draw.
