WLAN / LAN - Which devices will come?

I think the washing machine is currently arguing with the refrigerator. I'll offer them some indoor mediation.

You'll laugh but... this is exactly the task of certain professions that are becoming increasingly important. Bringing all the devices in the house/building into harmony and having them work together instead of against each other. Politically, this is desired and promoted through construction methods and regulations such as the Energy Saving Ordinance and others. For this reason, it is also increasing more and more.

The notorious iron in the refrigerator is the prime example.
