imlenti/MinerWatch ? reverse-engineered prompt

Build me a local first dashboard for my home Bitcoin miners that I can run on my own machine or a Raspberry Pi, and open in a browser on my phone or laptop.

I want it to find my miners on the same network, show each device at a glance with hash rate, temperature, fan speed, power, efficiency, shares, and uptime, and let me click into a miner for more detail and history charts. It should work with Bitaxe, NerdQaxe, Avalon Nano, Braiins, and read only support for LuxOS rigs. I also want simple controls where supported, like fan settings and safe automatic temperature control, plus alerts when a miner hits a new best share or finds a block.

Please keep everything privacy focused with no cloud and no telemetry, store data locally, and make the UI clean and easy to use. If you need to check the latest docs for any device or library, look them up online first.
