Hello. That "reboot on failure" option is NOT supposed to be on by default. Apparently there's a problem somewhere that causes that to turn on of its own accord.

I apologize for that.
As for why one works and one doesn't ... are they using the same firmware?

No worries, what's done is done and at least I have learnt from my mistakes and so not set the SSH password, until you find the bug

The firmware is indeed the only difference as 101 is an S3+ and 102 is an older S3 running OpenWrt Barrier Breaker r38031 / LuCI Trunk (svn-r9909) firmware, but I would guess so are many of the older S3 units that are using your code.
Cheers n beers

Would you please run the "get miner info" button in the latest beta on your non monitorable S3 and PM me the output please?
