Harlo OS is our own firmware. It replaces what your miner shipped with. Free, two minutes to install, and it ships on the Harlo B30.

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.


What it adds






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
- Open harlolabs.com in Chrome or Edge and pick your device profile.
- Plug the miner in. Take the screen off, or connect the USB port directly.
- Erase and install. A progress bar, a minute or two, then unplug.
- Power it up. Put the display back on and open the web interface.
The miner it was built for
The Harlo B30. 30 TH/s, about 433 W at the wall, power supply built in, Harlo OS out of the box.
