⚡ Smart Connect Wizard
Automatically detect the perfect port and starting difficulty for your miner. No share floods. No low-difficulty waste. Connect right the first time.
Live Difficulty Probe
Temporarily connect your miner to our test port. We'll measure your actual hashrate and find the exact right port and starting difficulty — automatically.
💡 Already know your hashrate? Use the quick port estimator on the homepage →We temporarily connect your miner to a private test port using a throwaway workername (not your real one). We measure how quickly your device submits work and use that to calculate the exact port and starting difficulty your hardware needs.
When the test finishes, we show you exactly which port to use. Reconnect your miner to that port using your real Bitcoin address and the same workername you used for the test — the pool will automatically start it at the correct difficulty from the very first share.
Have multiple devices? Run the test once per device, using each device's own workername. The result is saved per workername, so each device gets its own calibration automatically.
bc1q....laptop, enter laptop below. The saved result is matched by workername — if they don't match, the pool won't find your calibration.
Each device needs its own test with its own unique workername. A laptop, a Bitaxe, and a NerdMiner all have very different hash rates — if two of them share the same workername, the pool cannot tell them apart and will apply the wrong difficulty to one of them. Never use the same workername on two different types of hardware.
Do NOT run this test while that same workername is already actively mining on our pool — it will interrupt that session and skew the results. Stop or reconfigure your miner first, run the test, then reconnect it to the recommended port.
- Enter your BTC address and the exact workername this device will use when mining (e.g. laptop, bitaxe1, worker).
- Stop or reconfigure this device if it is currently mining on our pool. Then point it to: stratum+tcp://hmpool.io:9876
- Set the username to your BTC address and the workername you entered here (e.g. bc1q....laptop) and password x.
- Wait for the test to complete — usually under a minute.
- Reconnect your miner to the recommended port. The pool will now start it at the correct difficulty automatically.

the pool will automatically start you at the correct difficulty — no test needed again.
