The KNX-GSM Gateway offers a bi-directional communication between the EIB/KNX and the GSM network via short messages (SMS). This allows you to remote control and monitor your EIB/KNX installation with a mobile phone. Every authorized user can read from/write to EIB/KNX group addresses via mobile phone, if these addresses are unlocked in the KNX-GSM Gateway. Furthermore, the KNX-GSM Gateway provides the opportunity to send short messages to one or more receivers if certain events (e.g. “Temperature > x°C”) occur. This can be used to inform the user about interferences. The KNX-GSM Gateway supports the widespread mobile phone standard GSM. This is why it can be used in almost any place.
