3.3.1. Limitations and authorisation of access rights via KNX communication objects
If the Gira S1 is added to an ETS project, its communication objects can be used to prohibit or allow
access options via KNX, even at runtime. The access rights limitations defined via the KNX in the
remote installation always take precedence over the definitions in the portal. In this way, remote
access can be deactivated completely, regardless of the settings in the Gira Device portal, through
the use of group telegrams.
3.4. Access to websites on the remote network
Remote access via the Gira S1 enables secure access to websites on the remote network. For this
purpose, the unencrypted (HTTP) data on the remote network (see Figure 5) is transported to the Gira
Device portal server via an encrypted SSL/TLS connection and then to the web browser via an HTTPS
connection.

The easiest way to access websites on the remote network via HTTP is through the Gira Device portal.
Access via the Gira Device portal is quick to configure. For a description on this, see chapter 9.4
