I am an automatic service that looks for possible errors in ioBroker and creates an issue for it. The link below leads directly to the test:

https://adapter-check.iobroker.in/?q=https://raw.githubusercontent.com/instalator/ioBroker.mercury

Thanks,
your automatic adapter checker.

P.S.: There is a community in Github, which supports the maintenance and further development of adapters. There you will find many experienced developers who are always ready to assist anyone. New developers are always welcome there. For more informations visit: https://github.com/iobroker-community-adapters/info

Dear Adapter developer,

with js-controller 4.0 object definitions are now also checked that min/max in only provided for number/mixed objects and that the type of the default value matches to the object type.

If something is not correct this is logged as 'warning' or 'info' log.

Please also make sure to update to the lastest @iobroker/testing dependency 2.5.4 or to accept the PR from Apollon77 for legacy testing!

Please spent some time to verify your adapter by ideally starting with a fresh instance and do some actions and verify the log. If you see a warn or info log there from these checks please adjust the adapter and fix the relevant cases.

For questions please refer to ioBroker/ioBroker.js-controller#1749

Please close the issue after you checked it.

Thank you very much for your support to get the best experience for the growing numbers of ioBroker users!
