Question about AVM FRITZ!Box 7530 International / CH

MyStrom are devices in their own right and should not affect the operation of the FritzBOX, personally I recommend the use of AVM devices issue to control everything with a single APP

What is meant by this question?

All functions work with the MyStrom app, but it is difficult with a Swisscom app without a Swisscom router.

MyStrom devices under the Swisscom label make no difference in the MyStrom app!
