Encryption keys
Communication between Efento loggers and Efento Gateway can be encrypted with a key set by the user. If the communication is encrypted, devices which do not have the encryption key added, will not be able to decode the transmission and read the logger's measurements. You can add up to four encryption keys to Efento Gateway. Once a key is added, the gateway will be able to decrypt and read the measurements from all the loggers, which use the same encryption key.
Follow these steps to set or change the encryption keys:
Open the Efento Mobile App: launch the Efento mobile app on your mobile device and navigate to the “Nearby devices” section.
Activate Configuration Mode: when the gateway powers on, it automatically enters configuration mode (indicated by the blue LED blinking rapidly). To re-enter configuration mode later, quickly press the “PWR” button twice.
Connect to the Gateway: locate the gateway’s serial number in the app and tap it to connect.
Set encryption keys: Go to the Encryption tab (lock icon), enter the security key(s) and tap Save.
Changing the password
You can secure the gateway configuration with a password. Once set, users must provide the password to view or modify settings. Follow these steps to set or change the password:
Open the Efento Mobile App: launch the Efento mobile app on your mobile device and navigate to the “Nearby devices” section.
Activate Configuration Mode: when the gateway powers on, it automatically enters configuration mode (indicated by the blue LED blinking rapidly). To re-enter configuration mode later, quickly press the “PWR” button twice.
Connect to the Gateway: locate the gateway’s serial number in the app and tap it to connect.
Change the Password: Tap the three dots in the top-right corner of the app screen and select “Change Password”. Enter the new password and save the settings.
Custom CA certificates
The Efento Gateway comes with several commonly used preloaded CA certificates. If you wish to use a custom CA certificate, to do that:
Save the custom certificate on your mobile phone: certificates are uploaded to the gateway using the mobile application. To send a certificate to the gateway, it must first be stored locally on your mobile device.
Open the Efento Mobile App: launch the Efento mobile app on your mobile device and navigate to the “Nearby devices” section.
Activate Configuration Mode: when the gateway powers on, it automatically enters configuration mode (indicated by the blue LED blinking rapidly). To re-enter configuration mode later, quickly press the “PWR” button twice.
Connect to the Gateway: locate the gateway’s serial number in the app and tap it to connect.
Upload a custom certificate: Go to the Security tab (shield icon), tap Pick certificate file, select the certificate you want to upload, and tap Save.
Efento Gateway supports any certificate in PEM format. For security reasons, we strongly recommend using certificates signed by a trusted Certification Authority. However, for development or demonstration purposes, you may also use a self-signed certificate.
Restoring factory defaults
To restore the gateway to its factory default settings:
Quickly press the "PWR" button on the back panel 7 times.
The LEDs will blink sequentially, indicating that the gateway is resetting all settings and clearing all stored measurements from its memory.
Once the process is complete, the gateway will restart with its default settings.
Powering off the Gateway
To turn off the gateway press and hold the PWR button on the back panel for 7 seconds. The blue LED will switch off, confirming that the gateway is powered down.
