identical ups

[Deadfuntik]

faced with the problem of connecting ups. there are 3 ups, 2 of them are different models, but they have the vendorid and productid are exactly the same, as neither one nor the other has a serial number. I decided to connect one of them via the COM port. but for some reason, all three in the system could not be seen in any way. sees only 2 (which are different) maybe I'm specifying the port incorrectly? could you tell me? I specify the port that TrueNAS offers by default, and if that's the case, then how do I find out which path to this port? thanks in advance)

[Ups]
driver = usbhid-ups
port = /dev/uhid
desc = "TrueNAS Scale"
[ups2]
driver = blazer_usb
port = auto
protocol = megatec
subdriver = cypress
vendorid = 0665
productid = 5161
idleload = 10
[ups3]
driver = blazer_ser
port = /dev/ttyS0
protocol = megatec
subdriver = cypress
vendorid = 0665
productid = 0551
idleload = 10

I get the following error -
"Init SSL without certificate database
Error: Driver not connected"

Run nut-scanner to see what Scale sees, as UPS attached hardware. Then you can pick the correct drivers and ports. See Uninterruptible Power Supply section in this thread.

I managed to connect it all the same, but after a while, roughly speaking, the natural statistics are written - data stale.
prescribed pollinterval = 15
And in upsd.conf
MAXAGE = 25
DEADTIME = 25
but didn't help
