Move accessory to another WiFi network?

[olavt]

People need to re-configure their WiFi networks from time to time. Having to rebuild the Matter fabrics / networks as a consequence would be very painful.

I'm not sure how moving a Matter accessory device from one WiFi network to another would be done using the Matter SDK, but it looks like Apple Home makes this quite easy.

This should maybe be a function in the Python Matter Server too?

Yes we should create functionality for this. I need to dive into the details how to do this and if all devices support it.

any ideas how to implement this?

I would think. the following needs to happen:

• establish a CASE session
• arm failsafe timer
• use NetworkCommissioning cluster to update and then connect to the new network
• discover and re-establish a/the new CASE session
• invoke commissioningComplete to "persist" the data

But said this: This all relies on the fact that you can still use the existing connection to update the details AND already can use the new connection in parallel.
