How to Enable Mirroring
Enable the device to be Sharable in the Master Device settings
In the child device, enter the friendly_id of the device to mirror
How does Mirroring Work?
Once a device is set up to be Sharable instead of Standalone, anyone can mirror the device if they know the
friendly_id.Mirroring a device copies the plugins in the master device's playlist at the start. If the master device adds more plugins later, the mirrored device will not automatically receive them.
If the master device changes the visibility setting to "Standalone" from "Sharable", TRMNL will delete all the mirrored plugins from child devices that have the master device's plugins. This ensures the master device can always modify the mirrorable settings. However, independently installed plugins in child device would remain unaffected.
A child device can install its own plugins independently, and nothing will be shared with the master device.
If the master device has shared 5 plugins, the child device can delete 2 and retain only 3. However, deleting plugins from the child device will not affect the plugins on the master device.
Mirroring use case
Mirroring is useful when doing a Team purchase, where one Team Member acts as a master device and oauth's the B2B dashboard eg (Shopify, Google Analytics, Mailchimp, etc) without necessarily having to share the credentials with the rest of the team. The Child device will get the B2B dashboard while still being able to install their own plugins
Sharing a plugin with your grandparents / parents who are not technically sound. You can install a shared family calendar / note board / birthday remainder on master device and the child device will just get them.
