I created some template component for a socket to copy.

After I copied and configured my template 11 times I faced the following error:

@hgschwibbe Does the behavior of your issue change if you activate "Reine Web-Sockets (iobroker.ws) verwenden"?

Yes it change. I can create more elements now but the console is full of error logs:

I also recognized that I am able to create more widgets when I reduce the amount of sensors.
I removed the Ampere sensor and the additional lightning indicator from the socket image to release more widgets.
It looks like the webapp scales down as the number of sensors increases.
