the link wiki seems to be a bit out of date with regards to management of shutdown with UPS. I have a APC ups that is being managed by a NUT service on a RPi. The PBX is on another RPi but on the same UPS. I want to configure the PBX as a NUT client so that it can gracefully be shut down by NUT. Is it as simple as “apt install nut-client” and configuring the
/etc/nut/upsmon.conf file. There doesn’t seem to be a module, nor a relevant space under “advanced settings” to get the configuration done.
