PressurePlate is a handy add-on that lets you open and close the doors with the help of pressure plates. It's a very simple add-on that requires a couple of different items to be installed.

The first one is a workbench, which is a very simple tool that can be found in most houses. It's used to create and repair pressure plates.

The second item that you need to install is the mod. This is a simple tool that can be downloaded from the website.

Once the add-on is installed, you can find it in the settings of Valheim.
