Devices (Miners)

Single Operations

Single operations are applied to a specific device via its context menu. The menu can be accessed by clicking the ⋯ button in the device row or in the card header.

For MicroBT (Whatsminer) devices, Pause, Resume, Reboot, Change Password, and Change Pools are performed via the vendor's native API, similar to HashCore Firmware and Bitmain, starting with v1.0.0-alpha3. Other operations (Install firmware, Change preset, Change cooling mode, Diagnostic report) are not yet available for Whatsminer.

Reboot `v0.3.0`

A complete hardware reboot of the miner. The device fully powers off and reboots. Takes 1 to 3 minutes. A confirmation dialog appears before execution.

When to use: The device is frozen, unresponsive to commands, or a full restart is required after a firmware change.

Restart `v0.6.0`

Restarts the miner's software without a complete power cycle. Takes 30–60 seconds. Less aggressive than Reboot.

When to use: The miner is unstable, Hashrate has dropped, or new Pool settings need to be applied.

Pause `v0.3.0`

Stops mining without powering off the device. The miner remains accessible and responsive to commands but stops hashing. The status changes to Stopped.

When to use: Temporary device shutdown without physical disconnection — for example, during rack maintenance.

Resume `v0.3.0`

Resumes mining after a pause. The miner returns to normal operation. The status changes to Mining.

Locate `v0.6.0`

Physical identification of a device on the rack via blinking LEDs. When Locate is enabled, an orange blinking icon appears in the device row in the list. When pressed again, Locate turns off.

When to use: To find a specific miner among hundreds of devices on a rack.

Changes the Pool configuration for the device. Opens a dialog with three Pool slots — URL, Worker, and password for each. Substitution variables are supported: {account}, {worker}, {ip}, {mac}, etc.

Pool Presets `v1.0.0-alpha4`

A pool preset is a saved set of three stratum slots (URL, Worker, Password). Presets belong to the organization: they are available across all sites and are never deleted when devices or sites are removed. Presets function identically in both single and bulk pool configuration workflows.

Applying a Preset:

Open Change pools.
In the Pools presets section, select a preset from the Select pool preset to apply dropdown. Each entry displays its name, description, and preview of all three slots.
The slots will be populated with values from the preset, replacing previous entries. You can manually adjust them if needed.
Click Save and apply. Selecting a preset alone does not apply changes to the device until confirmed.

Saving a Preset — via the Save preset button:

If no preset was selected in this dialog, the creation form opens: Name (mandatory, 1–64 characters) and Description (optional, up to 128 characters);
If an existing preset was selected, you can choose Update current preset (overwrite) or Save to new preset (save as a new entry).

Editing or Deleting a Preset: Hover over a preset in the dropdown and click the gear settings icon. The form allows editing the name and description, or removing the preset via the Delete button with a confirmation step.

An Operations Manager can apply presets, but cannot edit slots manually or manage presets. Technicians and Viewers do not have access to Change pools. See "Roles and Permissions".

Change preset `v0.7.0`

Changes the overclocking preset for devices running HashCore Firmware. Available presets depend on the device model and autoswitcher settings.

Change cooling mode `v0.7.0`

Changes the cooling mode for devices running HashCore Firmware:

Auto — automatic fan control
Manual — manual fan speed setting
Immersion — immersion cooling mode

Install firmware `v0.6.0`

Installs firmware from a pre-created firmware set. Opens a set selection dialog.

Diagnostic report `v0.8.5`

Generates and downloads a diagnostic archive from the device. Available only for devices running HashCore Firmware. Progress and download are managed via the Activity Center. The file is stored for 2 hours after completion.

Change password `v0.5.0`

Changes the password for accessing the device's web interface.

Maintenance mode (Set to service / Remove from service) `v1.0.0-alpha1`

Marks the device as being under maintenance — an organizational flag, not a device state.

Set to service — via Maintenance → Set to service. Requires a Problem summary field and an optional Service reason. Once enabled, the device is marked with a 🔧 icon with a tooltip: start time, current duration, problem description, assignee.

Remove from service — ends the maintenance session. Prompts for a mandatory Result summary and an optional Result comment.

More details about the Service Mode tab and session history can be found in the Device Card section.

Device Operations

HashCore Pulse supports a wide range of operations on devices — both for individual miners and for groups. Operations are available via the device context menu or the group actions panel in the Workers list.

Group Operations

Group operations allow you to perform actions on multiple devices simultaneously. All group operations are processed through the Activity Center, where progress and results are tracked.
