Do Matter "owners" mind the integrated "kill switch"? 🧱

[WallyR (Wally)]

You have not understood the Matter standard.
The local functionality will stay in a Matter device just like it will with a Zigbee.

Endpoints will not be removed from the device when a certificate is being revoked.
The device will not even know the certificate is revoked.
The certificate is handled by the Matter server, not the end device.
The Matter server can decide what happens to the endpoints being presented to the user apps and the cloud services will most likely seize to recognize the device if the certificate is revoked.

There is not a kill switch in the device.
There is a certificate that the Matter server checks and the Matter server decide what to do then, like ask the user if he still trusts the device and want to continue using the local services.
A vendor can not just revoke the certificate himself. It is CSA that runs the certification service and it is them that decide to revoke a certificate.
The vendor and everyone else can request a revocation of a certificate, but not decide it will happen.

I suspect a lot of this discussion is too soon to ascertain about what future devices will come, and what future decisions manufacturers will make, and what the exact fallout will happen when a company will fold and/or stop supporting a device, or fundamentally change a devices available functionality.

@Saoshen

fundamentally change a devices available functionality.

The Matter protocol list a set of required endpoints (=functions) for each device type.
A vendor can not circumvent those.

Sorry Thomas, I have no idea why you make this things up (or imagen them how you do) but the cloud part of matter devices are totally seperated.

Just think of the chart I enhanced for you

@orange-assistant

The ewelink/sonoff cloud works independent and parallel to the local matter functions. The matter (WiFi) device is always connected to the (vendor) cloud and listen to commands which can be issued via app by the user.

@WallyR

like ask the user if he still trusts the device and want to continue using the local services.

Again Thomas, you mix up limited with local. The matter specs don’t talk local but about limited functions! Not the first time I specifically corrected your error because you made this false claims already

@orange-assistant

Upon discovering the revoked status of the device, the commissioner can notify the user. It is then the user’s responsibility to make a conscious decision regarding whether to allow the device to operate with limited functionality or not

Some not further described “limited” function might still be availability to the “owner”.

yes, we see that in the chart for the certified matter device: In short ON/OFF and scenes - everything(!) else can be cloud only functions
