@Canguingo Nothing needs to be done in the module, it should already have been there in parallel to the old ones for the last few versions of MM.
All you need to do is make the changes in config.js as detailed on the migration/depreciation part of the documentation. That will switch you over from the old modules to the new one.
What has happened with the 2.19 update is the old modules have basically been removed and just replaced with the notification that you see on the mirror screen now (and that will also presumably be removed going forward).
The config.js entry should look something like the template version you posted originally, except of course you will need to use your own specific API key rather than the abcde12345 placeholder and your specific location (unless you happen to be in Amsterdam).
