To activate your station, you must be the owner of it. If you got your station through a community, your station will be linked to this account. The community will then invite users to access the Sencrop stations they should be linked to.
If it's the first station you want to add, just fill-in the serial number and activation code available on the grey box of your station.
If you want to add another station, click on the "Plus" in the top right-hand corner of your screen and "Add a Sencrop". Then fill in the serial number and activation code available on the grey box of your station.
