In order to Remote Control a Home Connect Appliance, it needs to be added to the known Smart Devices.
Go to Control -> Smart Devices -> "Turn smart device on or off remotely."
Press the 
icon to add a Smart Device.
Add a "Washing Machine, Clothes Dryer, Dishwasher or Washer dryer combo"
At the "What brand is your washing machine?" question, select Home Connect.
During the flow you will be prompted to login to your Home Connect account.
Make sure you approve all actions so that Smappee can fully control the appliance with Remote Start.
Finally select the right appliance.
