This may seem like an odd one. Can HiveOS take in an input, like a serial command, or a message over TCP/IP with a command to shut down the miner?
The reason for this, is I’m going to be running the mining rig on batteries, charged by solar power. I’ll build a controller to interface with the battery level, and can send a message to HiveOS in whatever form required to let it know batteries are low and time to shut down. I’d rather do this than just cut the power.
Why am I doing this? well, its cost saving… Electic in the UK will be 28p per kwh in April, and likely to keep rising, costing around £750 a month. The miners are using 3.5kw. Going to get a larger solar array installed with batteries in excess of 50kwh. So during the summer I should be able to run 24 hours a day with no power from the grid. The winter will be pants, so will need to decide to take power from the grid or shut down. Its still making profit right now, but I’d rather keep the rigs going even if the energy prices rise further.
