I have purchased a new homey Pro and since I changed the box homeykit do not work if I m not connected to the local WiFi .all items are not responding in Apple home .
It used to work fine before .I have tried erasing homeykit and reinstall all devices but still the same
Please help 
Homey on its own works fine even if not on WiFi. .
Thxs Fabrice.
If it works locally, it’s not a problem with Homeykit but with your Home hub (iPad/Apple TV). Try switching the “Act as Home Hub” setting on it off and back on.
If that doesn’t work, you may be able to trigger a reset by changing the “bridge identifier” in the Homeykit app settings.
Hi …fast answer …! Many Thxs. I Didn’t think about that one … I have just checked and it seem to work with an old iPad which was set as a concentrator . I may need to relocate Apple TV or reset as you mentioned .
Many Thxs again for great support as it is definitely the track to follow .
And Many Thxs as well for the App it is just great to be able to use Siri with Homey
Kind regards
Fabrice
