General Questions

What is HashCore Pulse?

HashCore Pulse is a cloud platform for monitoring and managing industrial mining equipment. It allows centralized tracking of metrics, device management, and execution of operations on farms of any scale — from tens to hundreds of thousands of ASIC miners.

Do I need to install anything on each miner?

No. You only need to install one agent on any computer or server in the same network as the miners. The agent will automatically discover all devices within the specified IP ranges.

Which devices are supported?

Bitmain (Antminer), MicroBT (Whatsminer), Canaan (Avalon), Innosilicon devices, and devices running HashCore firmware (formerly Vnish) are supported. The full current list is in the Supported Devices section.

Does Pulse work if miners are behind NAT without a public IP?

Yes. The agent establishes an outbound connection to the HashCore cloud via port 443 (HTTPS). A public IP and open inbound ports are not required.

Agent

How many agents are needed for one site?

Usually, one is enough. Additional agents are needed if devices are in different isolated subnets — then one agent per subnet.

Can multiple agents be run on one server?

Technically yes, but it is not recommended. It's better to use one agent with multiple scan tasks for different ranges.

What happens if the agent temporarily loses internet connection?

The agent continues to operate locally and accumulates data. After the connection is restored, the data is synchronized with the cloud. Devices go Offline 5 minutes after metrics stop being received.

How to update the agent?

The agent updates automatically — it checks for a new version on startup and every 4 hours. If auto-update is not working, download the current version manually from the Pulse interface when creating an agent or via Show Credentials.

Can the agent be run on a Raspberry Pi or NAS?

Yes, if the device runs Linux (Ubuntu 20.04+, Debian 10+) and has an x64 architecture. ARM architecture is not officially supported.

Devices

Why is a device shown as Offline even though it is physically working?

Pulse sets a device to Offline if metrics are not received for more than 5 minutes. Check: device network accessibility from the agent server, the agent's status, and the presence of Unlock Configs for devices with non-standard passwords.

Why does a device show -- instead of metric values?

-- means that data is unavailable — the agent sees the device on the network but cannot authenticate and retrieve metrics. Most often, the reason is missing or incorrect credentials in the Unlock Configs of the scan task.

Can a device be added manually?

No. Devices are only discovered automatically by the agent during the scanning process. Ensure that the device's IP address is within the Scan Task's scanning range.

How many devices does one site support?

Pulse is designed to work with farms of up to 1 million devices. For very large farms, it is recommended to distribute devices across multiple agents.

What happens to a deleted device if it reappears on the network?

If a device was deleted from Workers and the agent rediscovers it during scanning, it will be added again as a new device. The history of the previous entry is not restored.

Operations

What is the difference between Reboot and Restart? Restart is a software restart of the miner's software without power cycling. It takes 30–60 seconds. Reboot is a complete hardware restart with power cycling. It takes 1–3 minutes. Use Restart to resolve software glitches, and Reboot when Restart does not help.

Why is a group operation performed slowly?

If operation throttling (Operation Throttling) is enabled in the site settings, commands are sent in batches with a pause between them. This is done to prevent peak load on the power grid. Increase Devices per packet or decrease Pause duration in the site settings.

Can a group operation be canceled?

Operations with Pending status (not yet started) can be removed from the Activity Center. Operations with In Progress status cannot be canceled — they will run to completion.

Why are some devices skipped during a group operation?

Some operations are only available for devices running HashCore Firmware (board management, diagnostic report, preset change). Devices on other firmwares are skipped and displayed in the Failed tab of the Activity Center with the reason "Not supported".

Dashboard and Metrics

Why does the income in the Income widget differ from the actual income?

The income calculation in Pulse is approximate — it is based on hashrate and consumption data transmitted by devices, and the current cryptocurrency value. Actual income depends on pool fees, accuracy of transmitted metrics, and exchange rate fluctuations.

Why are the charts not updating?

Check the auto-update setting — it might be turned off. Click the site button in the header to refresh data manually. Also, ensure that the browser tab is active — auto-update only works in an active tab.

What do AVG and RT mean in the Hashrate widget? AVG (Average) — the average hashrate over the selected time period. It shows the stable performance of the farm. RT (Real-Time) — the real-time hashrate at the current moment. It may differ from AVG due to temporary fluctuations.

Security and Account

What to do if I forgot my password?

On the login page, click Forgot password → enter email → receive a confirmation code → set a new password. After a successful change, you will be automatically logged in.

How to invite a colleague with limited access?

Go to Settings → Team → click Invite → enter email and select a role. For observers without management rights, select the Viewer role. More details on roles can be found in the Roles and Access Rights section.

Can I use one account on multiple devices?

Yes. You can log into Pulse from any number of devices and browsers. All active sessions can be viewed and managed in Settings → Security → Active Sessions.
