I’ve been using the OG tradfri devices since 2017/18 and have been very happy. Reliable, cheap to add a lightbulb or switch. Just works. Even integrated with home assistant v easily

Kind of a lazy question, but are any of these protocols substantial over 802.11, especially if you just use p2p/adhoc/mesh modes?
I haven't touched mobile networks in a while so I've forgotten a lot, but iirc the main concern of mesh networks was efficient routing (which has been solved with some cool algorithms) and power efficiency for devices transmitting (again could have sworn 802.11 and even bluetooth can already achieve this).
Zigby particularly stood out as annoying to me as it includes its own 2.4ghz physical layer stack which uses the same range as WiFI, which is already overcrowded as hell and relies on some CSMA/CA magic to make even the most apartment crowded area of APs function decently.

I mean, there isn't really any other choices for unlicensed consumer use? 5GHz is dedicated to WiFi. The sub-GHz bands would be great, as there isn't a need for much bandwidth, but it's a huge mishmash of frequencies that would require many different SKUs per device:
Initially, Dirigera will only support Matter device types that Ikea currently offers — so, no robot vacuums, door locks, or fridges. However, Granath says that as they launch more smart home products, the hub will be updated to support more device types.
Am I reading this right? Is there a filter possible where Ikea can decide to only accept Ikea ~mac addresses? If so, can they continue to ignore the wider product space?
... or will an Ikea thread hub automatically accept rando thread units as per standard and they're just using really bad sentence structure?
The second. It works with non-Ikea devices, but only works with device types that have an Ikea version like bulbs.
Ah! Fantastic. Thanks !
