Hi, Claymore!
I think, it will be useful to add a scheduler to reboot the rig (exec the reboot.bat), not miner in "-r" option. For example -r -180 - to execute reboot.bat if something wrong with gpus and to restart miner every 180 mins.
Or just to add one another option for calling reboot.bat.
I got some usb watchdog dongles from Aliexpress. They have an associated program and watch the miner and the gpus. If the miner, computer or a gpu stops working the dongle will reboot the computer. I have not installed them yet but on a test bench they checked out okay. Just search Aliexpress or eBay for "usb watchdog."
