Hi,
I'm a new Apollo BTC standart unit user, which I control from RasPi. I learned how to start, and stop mining - everything is fine here. I only can't figure out how to safely turn off the standard unit, so it can be disconnected from power? I want to understand how to avoid incidents when I'd need to remove the miner from power.
The second topic is that the stop script which use python inline command, to from what understand, reset the hashboard, is failing while piping to /dev/ttyACM0:
termios.tcsendbreak(3, 0)
termios.error: (32, 'Broken pipe')

What can be the reasons?

Any help is welcomed Thanks, best regards!
