I recently migrated from Smartthings to Hubitat. After porting/recreating/creating all my pistons, I attempted a backup from WebCoRE (using the “Backup piston(s)” menu item).
If I select all 30 pistons in the new Hubitat WebCoRE instance, and start the backup, about midway through, I get this error: “An error has occurred while retrieving backup… Please navigate to each installed instance before attempting a backup to ensure you have a fresh list of existing pistons and that the security tokens are not expired”.
If I select them in batches of 10, I still get that error. If I select in batches of 5, the backup succeeds.
On my previous Smartthings WebCoRE instance, I was able to back up all 30 at once. I’m still able to do so, in fact.
