Dear Charles,
thanks for all your information.
By using usbhid-driver we tested PR2200ELCDRT2U. FreeNAS was receiving "ONBATT" successfully and also initiated it's graceful shutdown!
So thanks for your information! :) I'm happy that it works!
Cheers,
Chris

Just a lucky guess :-) We tend not to know about changes like this until someone reports an issue.

Thanks, good to know. PR6000LCDRTXL5U would probably also work.

So, basically, the output is "upsmon parent: read"... however, this is all and there is no further output. But I think, there should be further output, shouldn't it? (some sort like "link established successfully").
Those are likely from the previous instances of upsd and upsmon - they look like the "errors" you get from sending SIGTERM to them.
The UPS drivers send their "connected" message to stdout, and they are not consistent about that, either. Pretty sure we have that logged as a bug.
Do you know the lowest syslog level FreeNAS logs by default? (debug, info, notice, etc. - see https://www.freebsd.org/cgi/man.cgi?query=syslog&sektion=3&apropos=0 for the list, and it might be in /etc/syslog.conf)

Again, the upsd and upsmon messages are secondary results from the driver not starting. Are there any log messages that reference usbhid-ups (the process name for your driver)?

^ Are these correct? (seems reasonable for a 4 x 12V battery)

Thanks, I'll add that to the HCL/DDL later.

At first glance, those numbers look reasonable. You can verify the load and voltage readings against your local configuration, but those aren't used for shutdown anyway.
The important thing is that the "ups.status" value includes "OB LB" (on battery, low battery) early enough for FreeNAS to shut down cleanly. We usually recommend testing this sort of thing with a dummy load, in case the signal happens too late, or the other portion (FreeNAS telling the UPS to cut power) does not work.
