Finally had a chance to replace the G5 with the new hub at the holiday house. Connecting the device not that easy. Holiday house only uses wi fi when we are there and turned off when vacant, also have cellular which the old G5 used. Got the system to work came home the next day and now the Smart Home app keeps dropping out and stating no device connected then will reconnect after a couple of hrs. I have down loaded latest firm ware seems to be a problem with the app. If the app is not working unable to get information i.e. power loss or illegal entry to the holiday house. Disappointed with new Hub system the old G5 system seem to be a lot simpler and more robust
