Use as a Repeater in an EnOcean Network
In repeater mode, the EnOcean Gateway works in single-level mode. Radio
telegrams received by the EnOcean devices are immediately forwarded once.
Reports that have already been forwarded are not re-sent.
An external antenna can be used to extend the module’s range; see Section
“Connecting the External Antenna.”
Additional information about radio transmission ranges is available in Section
“Connecting Devices” > … > “Typical Ranges” as well as in the EnOcean
document “APPLICATON NOTE AN001 – Range Planning Guide for Systems
Using EnOcean Radio Standard.”
4.4
SMART ACK Functionality
When functioning as a gateway, the EnOcean Gateway supports the “SMART
ACK” functionality. After request from the radio network, saved values can be
called from the radio module for the radio network device in an energy-efficient
manner.
To use this functionality, first the respective radio network device must be taught
in. The teach process must be initiated by the higher-order instance.
If the radio network device is taught in with the radio module, a short time is
needed for sending a “Learn Request” telegram is needed. This telegram is
provided by the EnOcean radio module.
