Manage two UPS
-
I have two APC Smart UPS connected to my LAN with network card AP9640.
Can I manage both of them from NUT in pfSense? -
In theory you could use NUT to monitor one and APCUPSD to monitor the other.

OK - maybe the best solution is to run NUT in a separate computer.
My setup looks like this:Powered by APC UPS 1:
pfSense (Protectli computer)
Synology NAS 1
Synology NAS 2
Fedora computers
Rasperi Pi (Home Assistant)
UnifiCloudKeyGen2Plus (Unifi WiFi)Powered by APC UPS 2:
Fedora computers
What do you sugguest as the best solution regarding my setup?
-
Can you use the management card's web interface from a workstation?

As a general rule, you want to choose a NUT primary based on speed of shutdown, availability and reliability. Systems slower to shutdown, such as Synology, should always be secondaries where possible.
For UPS 1, pfSense or the Pi would be the best choice for primary, with the rest as secondaries.
You should not use pfSense to manage UPS 2. Use one of the systems attached to the UPS as the primary, and have the others as clients. If there is one system that shuts down substantially quicker than the others, choose that as the primary.
Alternatively, since you have SNMP you can also have each host running as a NUT primary speaking directly to the corresponding UPS. If you do this, don't give any of the hosts write access to the UPS, and make sure to configure the UPS itself to have adequate time between declaring low battery, and mains cut off.

@dennypage I will go for your suggested solution:
UPS 1: pfSense as NUT server and the rest as NUT clients
UPS 2: one system attached to the UPS as the NUT server and the others as NUT clientsSince I don't have enough knowledge of NUT I guess I will be back several time to this forum.
Thanks for you gudelines and Merry Christmas !!!
