Why is the reaction to a signal from an EnOcean sensor very slow?

FAQ #101453

 

Symptom
The reaction to a signal from an Enocean sensor is very slow (the change of state of the sensor is recognized in the Fupla program after more than a second). In the installation an Omnio receiver/transceiver (gateway) produced before September 2009 or after July 2010 is used.

Reason
The EnOcean receiver and tranceiver from Omnio which have been produced before September 2009 and after July 2010 do require an acknowledge telegram from the PCD. As the PCD is not sending this ACK teleram, the receiver will repeat the telegram it received from the EnOcean device 3 times (with a retry time of several 100ms) before it will forward the next telegram.

Solution
In order to solve this problem, please use the FBox "OM APG03B-RS485 ACK" (see screenshot below). This FBox will send the ACK telegrams for all telegrams received.

In order to use this FBox, the following minimum FBox library versions are to be used:

• PG5 2.0: 2.6.125 or later
• PG5 1.4: 2.5.125 or later
