Hey Dirk!

Yes, the local digital twins Kanto component is the exact solution for such use cases ensuring a bidirectional synchronization when the connectivity situation between the device and the cloud comes back to "normal". In general, it is an enhanced component that you can use instead of the suite-connector that will handle both the remote connectivity and the local digital twins state management (persistency, synchronization, etc.). It is configurable to work with Hono the same way you have configured the suite-connector component.

The local digital twins component is ready to be released in our upcoming M2 release (scheduled for the upcoming couple of weeks at max). We will very soon (in days) include it in the Debian and RPM packages configs to be available for pre-release testing.

A configuration reference of the component is already available and we are prepping the concept guide explaining how it works and the applicable use cases in more detail as well as a simple how-to guide for a quick hands-on with the component. You can track the progress of these docs in the public Kanto task board as well ๐Ÿ˜Š

Let me know if this info is helpful and if any additional one is needed!

Have a great evening!

Subject: [kanto-dev] Local digital twins

In the docs and on github I see multiple references to 'local digital twins'. Is there already a tiny bit documentation on that?
Currently I've setup a connection on Ditto to stream all change events back to the edge gateway using the hono command topic.
That works well, but in case of power outage or anything similar that's not going to be enough.

According to the docs, the local digital twins are exactly the solution to this, but since these are not part of the deb package, I'm curious to the state of that component.

Could you shed some light on this, please?

Kind regards,
-Dirk Van Haerenborgh
