Auto-Tuning Capabilities by KillerInk · Pull Request #1152 · bitaxeorg/ESP-Miner

KillerInk · 2025-07-17T15:38:19Z

What This Does

This PR introduces a new set of features that significantly enhance the auto-tuning capabilities of the ESP-Miner. The auto-tune functionality is crucial for optimizing mining performance by adjusting key parameters such as power limit, fan speed, voltage, and frequency based on real-time conditions.

Auto-Tune Enhancements:

Dynamic Power Management: Users can now adjust the power limit to ensure optimal energy usage while maintaining high hashrates.
Temperature Control: Fine-tuning fan limits allows for better thermal management, preventing overheating and potential hardware damage.
Voltage and Frequency Adjustments: The ability to modify step voltage and frequency settings helps in achieving the best possible performance from ASICs under varying conditions.

Benefits:

Optimized Performance: By dynamically adjusting parameters, users can maximize mining efficiency and profitability.
Improved Hardware Longevity: Better temperature control and power management contribute to the longevity of the mining hardware.
Remote Configuration: The API-driven approach allows for remote adjustments, making it easier to manage multiple miners or integrate with external monitoring systems.

By enhancing the auto-tuning features, this PR aims to provide users with more control over their mining operations, leading to improved performance and potentially higher returns.

this is related to #1099

KillerInk · 2025-07-18T03:49:18Z

have to extend the chart, that it shows the applied voltage, frequency and fanspeed to have somekind of feedback for the user what is is happening.

duckaxe · 2025-07-20T14:05:45Z

Still draft?

KillerInk · 2025-07-20T17:13:35Z

Yes hope I have tomorrow time to extend the chart and add the missing stuff on esp side to statistic and livedata.
Think that my current chart is a little overdone and contains to many datasets.
Or I keep it as it is and add it as extra menu item where the dashboard, pool, update items are.
But then I still have to cleanup unused datasets.
I'm open to every suggestion

Maybe it's a good idea to wait for #955 before any changes on the home chart?

KillerInk · 2025-07-24T04:07:09Z

Maybe it is, no hurry. will keep this up to date with master

KillerInk · 2025-07-24T12:36:41Z

well the chart part is more or less obsolete with #955
so i can drop it an keep only the settings part

this feels weird but idk

Its there that http server dont have to check not used keys for the info

main/http_server/axe-os/src/models/ISystemInfo.ts

    isUsingFallbackStratum: boolean,
    poolAddrFamily: number,
    frequency: number,
+    frequencySet: number,


whats this for?

Its for the settings to show the frequency from the config and not that one used by auto tune.

without it it looks like this

with it like this

hmm, i think i prefer the furst as its easier to adjust the autotune if it gets confused. i got it into a state where it was holding a high voltage and low clock to reach the target temp instead of doing the opposite.

that still do work. i only show the saved frequency in nvs as it would be expected. when you set the frequency it gets applied.

KillerInk · 2025-12-09T14:48:22Z

seems to not pay attention to when auto fan control is enabled, switched to manual at 90% and it started dropping the clock

yes its the old problem. i gonna workaround inside autotune

… same for target temp when switching back to pid
