Hi all, I have often thought "it would be nice to be able to do a diff between the DB and network" .. Has anyone else had this thought .. is it possible? ie - what has changed on a network since it was installed .. what is different betwen in the database and on the network? at the device level it is easy to see if a device has been replaced as its serial number will be different - at least, assuming it is the same model on the same network address .. maybe even more (less?) obvious if there is a missing device and new device of similar model at another address .. maybe hard to work out from the network any mapping if multiple have been replaced! what about a relay/dimmer/etc - if a channel group address has changed? Cheers, Mal.
