Secure remote access and protection for your KNX bus

The Enertex® ENA² provides secure remote access for your mobile devices or remote management of your installation, and protects your building network against fraudulent access by local network devices. Additionally, the ENA² stores all telegrams in an integrated database.

The configuration is optimized for the needs of your SmartHome, without any security tradeoff, ensured by recent security techniques and well-tested VPN software.

The ENA² is no cloud device, but leaves the control to whom it belongs: You. Enertex offers a free relay server (optional). If used, changing the internet router configuration is not required and remote access works independently of your local internet provider's configuration (IPv4, IPv6, DS-Lite). Your end-to-end encrypted data is only forwarded by the server, without any risk for your privacy. User permissions to open remote a connection can be controlled with KNX group telegrams.

Connected vacuum cleaners make the “Protected Network” inevitable to protect your KNX IP devices. The device has two physically separated ethernet interfaces. Your existing LAN on the first interface is typically managed by your internet router, and connects your computers, Smartphones, and IoT devices. On the second interface, the ENA² manages the “Protected Network” for your KNX IP devices. The separation prevents any other device from accessing the building infrastructure without permission. With the easy-to-use browser-based configuration on the device, you manage the filters.

To understand what happened when and why, the ENA² stores all telegrams (~ 100.000.000 telegrams, depending on data type). The database can be exported for the ETS or analyzed directly on the device.
Generate time-value-charts or find typical configurations errors with a few “clicks”, e.g., read requests without or with multiple responses.

Our ENA² is the only device to provide remote access, a “Protected Network” and a database for KNX telegrams.
