Hi, @dominikriemer and @tenthe, could you please review this PR? Please let me know if anything needs to be changed or added!

[dominikriemer]

Thanks @purplesmurf45!
I did a rough first review and raised a few questions :-)

[purplesmurf45]

@dominikriemer I have made the requested changes. Can you please check now? Let me know if anything else needs revising!

Hello @purplesmurf45,
thank you very much for the PR. Maybe we can directly create a cypress e2e test for this new functionality.
My suggestion for the test is:

• Create two adapters
• Click on the button Stop all adapters
• Click on the button Start all adapters
• Confirm that the live data arrives

You can find a sample test in [1].
I am happy to assist you if you need help.

@tenthe @dominikriemer I have added cypress tests for the newly added buttons. Could you please review the latest changes whenever you are free?

[dominikriemer]

@tenthe can you please have a look at the tests?
I'm not sure why CI is not triggering all smoke tests.

@purplesmurf45 thanks a lot for this great PR.
Really cool that it also works directly with the Cypress test 🚀
