Measured, not self reported

The miner stops grading its own homework. Power comes from a smart plug at the wall, hash from the shares your pool accepts.

True Power: measured at the wall with a Matter smart plug

True Power: a Matter smart plug feeds the miner its real draw from the wall

What it adds

Stock firmware versus Harlo OS, row by row

Quad pool mining: four pools at once, with a split you set

Schedules: mine on your power bill's terms

Idle mode: about 2.5 watts, still on the network

Home Assistant: the house lights flash when you find a block

Vision, coming soon: your miners from anywhere

Plus Stratum V2, three saved networks with Ethernet always winning, and a display you control.

Make the screen yours

Eight display rules and a slot for your own artwork. From the Harlo Labs Discord this morning.

Installing it

  1. Open harlolabs.com in Chrome or Edge and pick your device profile.
  2. Plug the miner in. Take the screen off, or connect the USB port directly.
  3. Erase and install. A progress bar, a minute or two, then unplug.
  4. Power it up. Put the display back on and open the web interface.
