Share a Train at Home dashboard: pools and roles in the hub

If several people run Train at Home machines together, whether friends or a small team, subnera hub lets you look at all of them on one dashboard. The tool for that is the pool. This guide covers what a pool is, how to create and share one, what each role can do, and how a Mac is lent into a pool and taken back. If you have not set up the hub yet, start with the fleet hub guide.

What a pool is, and what it is not

A pool is a group of machines on a dashboard, with a list of people who may see it. That is all. It is not a reward-sharing mining pool: nothing in subnera hub pools, splits or redistributes earnings, and each Mac keeps reporting under its own name and hotkey. The earnings figures shown are read from public Macrocosmos data for the machines in the pool. subnera hub makes no promise about what a machine will earn. subnera is unofficial and not affiliated with IOTA, Macrocosmos or Bittensor.

Every account has a Personal pool, created automatically. Your Macs live there until you move them. A personal pool cannot be shared or have members. To work with other people you create a shared pool.

Create a pool and switch between pools

1. In the hub, open the pool switcher. It lists every pool you belong to.
2. Choose New pool, type a Pool name and press Create pool.
3. You become the owner of the new pool. Choose a pool in the switcher at any time to see its fleet, alerts and earnings.

The switcher is only a preference for what you see first. Access always comes from your membership in the pool, never from which pool is selected.

Invite people

Invitations are managed in the pool's settings, under Invitations. Anyone with the right to manage members (admins and the owner) can create them.

1. Choose a role for the invitee.
2. Optionally enter an Email (optional). If you do, only the account signed in with that address can accept.
3. Press Create invitation and copy the Invitation link.

The link is single-use, valid for 7 days, and shown only once, so copy it before pressing Done. Anyone signed in with the link can join until it expires, unless you locked it to an email address. Open invitations can be revoked from the same list. No email is sent: you pass the link on yourself.

The invitee opens the link, signs in or creates an account, and presses Accept. They see the pool name and the role they are offered first. A person cannot accept their own invitation, and an account that is already a member is told so.

The four roles

Roles are cumulative: each role can do everything the one below it can do.

Action	viewer	member	admin	owner
See the pool's fleet and machines	yes	yes	yes	yes
Export earnings	yes	yes	yes	yes
Read live miner logs	no	yes	yes	yes
Send commands to a Mac	no	yes	yes	yes
Lend your own Mac into the pool	no	yes	yes	yes
Manage the pool's machines	no	no	yes	yes
Manage alert channels	no	no	yes	yes
Invite, change and remove members	no	no	yes	yes
Rename the pool	no	no	yes	yes
Delete the pool or transfer ownership	no	no	no	yes

Two details matter. First, a role only manages strictly lower roles: an owner can invite admins, members and viewers, while an admin can invite members and viewers but cannot create another admin or change one. Second, commands sent from the hub still need the Mac itself to have Allow remote control switched on; see the remote control guide.

Lend a Mac into a shared pool, and take it back

Moving a Mac is done from its machine page, with Move to pool.

• Lending. A member (or higher) of a shared pool can move one of their own Macs from their personal pool into it. The Mac is recorded as lent by you and shows Lent by your email.
• Taking it back. The lender can move the Mac back at any time. A lent Mac can only return to its lender's personal pool, so it appears as Back to lender for the pool's admins. An admin or owner of the holding pool can also send it back.
• Revoking. Only the lender can revoke a lent Mac from the hub. An admin cannot destroy a Mac that was only lent.
• Pool-owned machines. A Mac enrolled directly into a shared pool, with no lender, can be moved between shared pools by someone who is an admin in both.

A Mac can never be moved from a shared pool into someone's personal pool unless it was lent from there.

Leave a pool, remove someone, delete a pool

• Leave. In the pool settings, choose Leave pool. Machines you lent go back to your personal pool. An owner cannot leave: transfer ownership first with Transfer ownership, after which you become an admin.
• Remove. Admins and the owner can remove people strictly below their own role. Their lent Macs also go home.
• Delete. Only the owner can delete a pool, after typing its name to confirm. Pool machines and alert channels are deleted with it, lent Macs return to their lenders, and the earnings of the pool can no longer be exported, so use Download earnings first.

The pool settings also keep an Activity log of who joined, left, changed a role, moved a machine or created an invitation.

For what data leaves each Mac, see the privacy guide.
