I don't understand people criticizing this. Didn't they read the article? The new Suzi stuff doesn't want to replace Zigbee, and the new zigbee version is backwards compatible.

What is the pain there?

I would assume, yet _another_ standard. There are a bunch of them, and product builders are taking a long long time to properly implement, and often buggy. And they often result in the consumer need to buy yet another gateway/router, and learn the ins/outs and quirks of another protocol that won't work properly in years, all the while two new competing standards have been introduced. An example - how long has Matter existed? Yet, it hasn't had a profile for smart plugs with energy monitoring (eg the 12$ IKEA one). Such a basic use case...

And all this so Samsung et al can siphon off more user data and show more ads.

I fully understand the consumer viewpoint.

But, it's great news imo with sub-GHz (Suzi)!
