Every MMG D:ONE discovers the others on the network by itself. Open the Fleet tab on any unit and you’ll see them.

There is no central server to run and nothing in the cloud. Any unit can act as the controller — so there is no single box whose failure takes the estate down with it.

What you can do today

From the Fleet tab you can see every unit, its group, its live health, and change which NDI® source it is showing.

Fleet control currently covers source assignment. Bulk operations — remote restart, pushing configuration, group-wide commands — are not available yet.

Groups

Tag units into groups (“Foyer”, “Stand B”, “Level 2”) so a large estate stays readable. Each unit also carries a serial and a label: address it by serial, read it by label.

Units do not join a fleet just by being on the same network. Enrolment is deliberate.

1. On the controlling unit, choose the device you want to add.
2. A six-digit code appears on that device’s own screen — the HDMI output.
3. Type the code into the controller.

Because the code is shown on the screen you are standing in front of, someone merely sitting on the network cannot join a device to a fleet they shouldn’t.

The code expires after 10 minutes, and a device locks out after five wrong attempts.

How control travels

Once enrolled, units talk over an encrypted mutual-TLS channel. Each unit holds its own certificate, signed by the fleet’s authority and bound to its immutable hardware serial — so a peer is verified by identity, not by an IP address that anyone could claim.

Units outside the fleet cannot be driven from it.

Every unit reports on itself, and its health is visible both on its own Health tab and next to it in the Fleet list.

Power is the one to watch

Under-powering is the most common cause of odd behaviour in a field installation, and it rarely announces itself — it shows up as a glitch, weeks later.

MMG D:ONE reports the actual input voltage it is receiving. A unit being quietly starved by a long cable run or a weak supply tells you so, in numbers, before it becomes a problem in front of an audience.
