I am a fan on Hiveos right now. Recently I altered the hashrate watchdog script to work with the USB watchdog so that way we do hard resets instead of using a command.

Please check out my video if you like subscribe.
This is the video guide I made:

First thing is to plug in your USB watchdog correctly.

Turn on the Miner and SSH into it.

Edit the file /hive/bin/wd

Replace: nohup bash -c 'sreboot'
with: /hive/opt/qinheng/hl340 reset
different watchdogs will use a different script

Then restart the service with this command: systemctl restart hive-watchdog.service

And done.

You can test by setting the hashrate watchdog to an unrealistic expectation and then wait and watch the USB watchdog work.

If you have any feedback let me know thanks! and I hope this was helpful to the few of you out there
