Sensitivity is Not Applicable for contact sensors.
I believe they meant the preference is Not Available yet. Sensitivity does apply to contact sensors since it’s a type of Boolean Sensor and uses the same CurrentSensitivityLevel attribute.

Hi, @mocelet
I already shared your past comment and this one with the corresponding team.
If it’s a certified device, changes cannot be released without following all the development and testing processes between ST and the partner. So, this is why we haven’t provided further feedback since we don’t have information. We have only shared your feedback with the corresponding team, and once they provide further details, we’ll let you know. Just as a heads-up, this can take a while.

Thanks, it’s a standard Matter 1.4 feature for sensors, nothing vendor or model specific. I mentioned Aqara because they’re among the first to support these Matter 1.4 features.
Same goes for the Matter OTA support, Aqara and others publish the updates in the Matter DCL and it’s up to the platform to apply them or not.@SmartThings said they would eventually allow any update in the DCL but for the time being updates would be allowed on a manual basis, except the list of three devices hasn’t changed in two years.

Quick note: if you use WiZ lights with Matter and they’re configured with the WiZ app too, know that the latest automatic firmware update to 1.35.0 is going to break things and result in wrong brightness when you turn on the light.
It’s not you, it’s not SmartThings, it’s the firmware 
. Guess updating devices is a double-edged sword…
I’ve had to add explicit brightness setting to my routines that just turn on lights, otherwise they would be super dim when turning them on.
Edit: Found the issue, it’s discussed in the reddit post, basically it’s a wrong default value for the OnLevel attribute. It’s been always wrong but they didn’t use it, now they’ve fixed other Matter related bugs and the effects of the wrong value are arising.

It appears the price of New Aeotec V3 hubs has increased to $149.99 at SmartMatters.co. Still Out of Stock at this time.
Sweet!

Samsung began making its platform less dependent on the internet and encouraged developers worldwide to create so-called Edge drivers for SmartThings. With the new hub, this transformation now seems complete. Matter products, with their local approach, no longer require an Edge driver anyway
Looks like the press release was successful in making even specialized media believe that the Hub 2 provides more local features than previous hubs.

Came across a IKEA DIRIGERA hub in a thrift store that felt like a steal now that they’ve enabled more features.
-
The Matter bridge works fine (except for this) and it updates the firmware of devices automatically, but custom drivers in SmartThings usually provide more features. It’s useful for multi-admin scenarios if you want to keep devices local.
-
The Matter controller is beta and disabled by default, can’t say I was successful, just tried to share a Nanoleaf light from SmartThings to the IKEA Smart Home app and failed.
-
The Thread border router is an OpenThread implementation using Thread 1.4 but IKEA closed the configuration API before I got it so couldn’t play with it.
Initially it created its own Thread network which was disappointing considering time ago I shared the ST network credentials and set as the preferred one in my Android phone thanks to the Home Assistant companion app so any TBR (even 1.3) could join it.
Well, I’ll be damned… just checked today and it joined SmartThings network! I didn’t do anything, maybe that happened when sharing the device? Or after a restart?

Couple more notes about the DIRIGERA.
First quick one, if you change the name of a bridged device in SmartThings it changes in IKEA app too!! 
It’s a Matter feature but caught me off guard!
Second one, I was able to use the hub as Matter controller, directly adding a spare Nanoleaf light. It would disconnect a lot though (it’s beta after all), which lets me appreciate how good SmartThings / Aeotec hub deals with Matter over Thread devices since it was probably a Matter controller issue, the Thread network is the same after all.
DIRIGERA has some nice tricks for Matter lights:
- It is 100% local, including the app, so you can fully control the lights offline, unlike… .
- There are super-easy to create locally executed wake-up and wind-down routines that produce excellent transitions, although I don’t know if they use actual Matter transitions or just update the attributes very quickly (SmartThings equivalent is cloud-based and updates every 60 seconds). Unfortunately, you can only schedule them, can’t run them on demand with, let’s say, a button.
- You can “link” IKEA dimmers to Matter lights with just a couple taps in the app. Of course that’s not a real binding but a glorified automation, but it works great! Even the continuous start/stop dimming while held is SO well done, instant and smooth. I’ve never been able to create an automation like that in SmartThings, not even with custom drivers to expose the release action and send specific Matter commands. Usually the part that fails is the “instant” since the automation takes too much time to run (maybe I need the V4 hub after all…) so by the time I release the button and the transition stops it’s already too late and it’s better to just go step by step.
Edit: I’m almost convinced IKEA uses the native Matter commands for dimming with the remote (Move, MoveWithOnOff and Stop), the same used in Zigbee by the way. I’ve been able to replicate the behaviour with SmartThings and a custom driver achieving good enough performance. Somehow it performs better than last time I tested. Still, DIRIGERA is clearly faster at sending the stop command when you release the button so it stops dimming instantly and not a bit later. Understandable since the automation is pretty much hardcoded whereas in SmartThings it goes through the automation engine, drivers for buttons, lights, etc.

The article just states the information from the Community post:
I also talked about it in the Matter subreddit and had quite the reception!
