Hello,
For the Magic Din Rail, at least one Magic 1 or Magic 2 adapter is required for the respective network-connected devices. Older "Devolo Dlan" adapters are not compatible with the Magic set. Unfortunately, I didn't know this at first and had to read the specifications in more detail after buying the Magic series.

I have been using the Magic2 Dinrail successfully for about half a year.
It has to be installed in the distribution box or in an equivalent place! Therefore, you need the appropriate expertise. To avoid accidents and to follow the regulations otherwise definitely hire the electrician.... Just that it is mentioned at this point.
Greetings
Thomas
