There are some hackspaces in this world. The Space API was developed to exchange information about hackspaces in a standardized way. This API contains data about the hackspace such as whether the door is currently open for visitors and guests or not.
As a modern maker and hackspace the Toolbox is of course included and shows not only on the website if the hackspace is open, but also via Space API.
In the Toolbox itself there is a switch to change the status of the hackspace to
closed. The git to the self-made server backend can be found on github.com/see-base/spaceapi-server.
The source code of the switch itself is on gitlab.com/ToolboxBodensee/webseite/spacebutton.
The Space API is also triggered by a newly installed door control and the status can be retreived via the internal Slack channel.
