Harlo OS: one free firmware for every miner you own

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.

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

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.

The community loves it

What owners posted in the Harlo Labs Discord this week, unedited. Thor P2s going up, a Bitaxe pair hitting a test block within the hour, and one display that shows everything at once.

I have a standard NerdQX (White) with ESP32-S3 and 16 MB flash. Your public Harlo 0.1.49 installer recognizes the ESP32-S3/16 MB controller, but the firmware image does not contain a nerdqx hardware profile, while HeliumDeploy’s NerdQX product listing advertises Harlo OS. Is there a private/beta NerdQX profile or factory image available for existing NerdQX owners? P.S. it made a huge improvement on my NerdQaxe++ Hydro on temp. I was getting 60 – 62c on NerdOs, yours gives me a cool 55c which is amazing. Thats why I am asking about the NerdQx because I have both the White model (Like what you sell) and the LOUD Orange box miner. I want to move them to HarloOS. Thank you.
