Update after power failure

[electrokinisi]

Hi gays.

I want to update read request a group address after a power outage.
In the installation I have a voltage analyzer that measures the voltage.
Does anyone have any idea how to enable rebroadcast for update.

Just enable “Read during start-up” in the object properties and make sure the read flag is enabled in the ETS programming so the device object in that group address is allowed to answer.

Thanks for the answer, very useful. But the wiser  is in ups , maybe there is in code to enable reading  when the voltage comes back. 
Thanks in advance .

If you have info when the power outage did happen then you can do something like this

You can monitor bus connection status via a script: https://forum.logicmachine.net/showthread.php?tid=293
It might not detect short power downs though. A more robust solution is a KNX device that sends something when powered up.
