UPS, USB connection and NUT

Hi

Is it possible to connect the Rutx09 to a UPS with USB monitoring and load the NUT server on Rutx09 so that I can monitor the battery status etc?

Hello,
Sure, install nut-server:

opkg -e /etc/opkg/openwrt/distfeeds.conf update
opkg -e /etc/opkg/openwrt/distfeeds.conf install nut-server nut-driver-usbhid-ups

Regards,

Thanks again - will give this a go tomorrow.

Sorry, quick question before I get started. Will firmware updates wipe all the work I am about to do and mean I need to do it all again?

Yes. Put the name of the files you want to preserve across a firmware update in /etc/sysupgrade.conf

Good afternoon,

I can see that @flebourse has kindly provided you with a method to answer your query.

Please after testing, advise if you need any further assistance.

Thank you, kindly help me find the files that should be protected from a firmware update

To date i have added

/etc/config/nut_server
/etc/nut/
/etc/config/nut_cgi
/etc/config/ups
/etc/config/nut_monitor

/etc/config is in the default list no need to add it there.
/etc/nut only contains links to autogenerated files no need to protect them either.
You’ll have to reinstall the nut packages after a firmware update.
