Often the one solution is to keep trying and trying until it finally succeeds @Tony_Gorham .
Using your phone’s mobile data connection instead of WiFi seems to help me.
@Rudi_Hendrix Yea, this toggle turns itself off every x days. This has been going on since I use Homey (2020!).
Discussing with Support back then got me this unsatisfactory reply:
I’ve added 2 Ggl Home automations to sync devices twice a day automatically.
Note: the existing devices still work when the toggle is disabled. It’s only used for syncing new and for removing old/unselected devices.
