It seems that MM is not available?
I tried to write shutOtherModule function in node-helper, and MagicMirror told me that

ReferenceError: MM is not defined

How could I get access to MM object? Why my MagicMirror responded me with a blank mirror when the function is called after receiving “DOM_OBJECT_CREATED” notification?

Finally I deleted the node helper, it seems that MM functions does not work in node helper functions.
But the setTimeout function in notificationReceived function still does not work with “DOM_OBJECT_CREATED”.

turn on the developers console with Ctrl-Shift=i, or npm start dev, then you can use the console and sources tabs to see errors in the module.js and also put stops on code and look at the variables

as u found, the MM variable is only available in the module.js

I use MMM-ModuleScheduler to show or hide modules. It works very simple out of the box.
