[Nut-upsdev] Question about voltage threshold setting in NUT

[Shen Chuan]

Hello Charles,

Thank you so much for your help. Just run upsc and it is possible that
input.transfer.low is the one because we used power regulator to bring down
the power around 84v and then the ups sent the power loss message to PC. Do
you think some others may take effect for the low voltage? Just have the
upsc result attached.

Then I retried input.transfer.low, default.input.transfer.low,
overwrite.input.transfer.low. Looks like it still can not write to those
params.

$  sudo upsrw -s input.transfer.low=70 -u * -p * ups
Unexpected response from upsd: ERR READONLY

$  sudo upsrw -s default.input.transfer.low=70 -u * -p * ups
Unexpected response from upsd: ERR VAR-NOT-SUPPORTED

$ sudo upsrw -s overwrite.input.transfer.low=70 -u * -p * ups
Unexpected response from upsd: ERR VAR-NOT-SUPPORTED
