Backup and restore system, devices and schedules to Heathub using HA

My Wiser Heathub has stopped talking to the Wiser cloud. So I cannot turn off Away mode until I get home. Much grizzling! After various efforts Wiser support now say factory reset the hub and then recreate the system.This will be a lengthy task.

I can see that individual schedules can be written out and restored but I was hoping to backup all the devices, schedules and configuration data etc in one go, then restore when I have established communications with the hub. Is this a practical proposition?
