Socket.io is up and running:

[SKB-CGN]

Please change change in Web Adapter socket instance to integrated. Then the connection is working.

Do you need socket.io?
In most cases the integrated socket instance in Web Adapter is working fine.

[Sineos]

In fact the web adapter is using web sockets:

Otherwise the VIS editor is not working correctly for me.

Edit: But you are right, "integrated" works, but I would like to avoid running multiple web instances (if this would anyway be possible because neither in your adapter, nor in VIS I can choose the web instance).

[SKB-CGN]

Instance integrated is also working with VIS under all "standard" conditions.

What is not working inside the VIS Editor, if on integrated instance?

Currently, I am not able to provide any other solution.

[Sineos]

What is not working inside the VIS Editor, if on integrated instance?

For example importing projects. Have not encountered anything else but this one for sure is not working under "integrated" and also not working under "socket.io" (at least for me - just retested it)

[SKB-CGN]

Means, that one is neither working with integrated and socket?

So, why using socket instead of integrated? :)

[Sineos]

Sorry for not being clear. As stated in #17 (comment) I'm using the web instance with web-sockets because otherwise the VIS editor is not fully working.

Energiefluss is only working with "integrated" in the web instance but not with "socket.io" and also not with "web-socket".
Testing with socket.io was only during troubleshooting VIS and Energiefluss

[SKB-CGN]

Ah ok. Currently the adapter only works with integrated. Sorry for this.
