Communication functions
9.1 Bluetooth pairing
Bluetooth Low Energy communication allows access to the sentinel Energy trip unit from a
smartphone running the Hager Power touch application (see Chapter 2.3 Hager Power touch
application).
The Bluetooth Low Energy connection is only possible between one sentinel Energy trip unit
and a smartphone at the same time.
During the connection, the trip unit is identified by the letters "HG" followed by its serial
number.
To establish a Bluetooth Low Energy connection, the following conditions must be met:
• the sentinel Energy trip unit must be powered,
• Bluetooth Low Energy communication must be activated on the trip unit,
• you must have a smartphone running the Hager Power touch application,
• you must have access to the trip unit and must be no more than 10 metres away for an
optimal connection.
N.B.
The smartphone must be running IOS 13 or Android 7 (or higher).
Activation of the Bluetooth Low Energy communication
Bluetooth Low Energy communication is deactivated by default.
Bluetooth communication can be activated permanently or for a predefined period. In the latter
case after there has been no activity for a certain amount of time, the connection will be ended
automatically once this period has elapsed and the trip unit's Bluetooth setting is deactivated.
The automatic disconnection period is 30 minutes by default and it can be adjusted.
Bluetooth Low Energy communication is shown on the sentinel Energy display by a blue icon.
