Just thought I'd float the idea of synchronising more than just modes between hubs.
Although not a major task in setting up a new HE hub, I was thinking some of the localization settings could potentially be synchronised, such as location (lat/long), timezone, temperature scale, etc. I would suggest doing it in a similar style to the modes, e.g. on a "child" hub, choosing to follow the settings on another HE hub.
Other possibilities could include synchronising:
- Scheduling of regular backups
- Files in File Manager
- Drivers / Apps Code
