NUT server and UPS general question

@netboy Okay, that looks much better.

Now add this

[monuser]
password = secret
upsmon slave

to "Additional configuration lines for upsd.users" in the Advanced settings section.

Now go to this post and follow the instructions to allow access to the NUT port from the LAN interface. I recommend that you choose option 1.

Following that, you can confirm operation by going to the pi and executing the following command:

upsc ups@192.168.0.1
[Based on prior posts, I am assuming that 192.168.0.1 is the LAN IP address of your pfSense firewall]

When you run the upsc command, you should see all the variables of your UPS displayed.

Lastly, for the pi end, put this in upsmon.conf:

MONITOR ups@192.168.0.1 0 monuser secret slave

@dennypage I guess the MONITOR must be like below (see bold) - correct - Probably you have a typo?

MONITOR ups@192.168.0.1 0 monuser secret slave

You are correct. I copied and pasted from another example. Sorry about that.

@netboy SUCCESS!!!
I had to make an entry in hosts.conf for pi

MONITOR ups@192.168.0.1 "Netgate UPS"

Worked. I sincerely thank you very much for all your help.

@netboy Probably last question....

I want to shutdown everything attached to ups in netgate only when "battery low" in ups - How do I configure this functionality

Well, you are in luck... that is the default behavior of NUT.

Anything else connected to the UPS that is capable of running NUT would monitor the master on pfSense just like the setup you did for the pi, with the exception being that they would use power value 1 rather than power value 0. Like so:

MONITOR ups@192.168.0.1 1 monuser secret slave

All the hosts will shut down when the UPS declares a low battery situation. You can read more here.

@netboy Since synology also uses NUT I am struggling to MONITOR the same using raspberry pi..... Created a user in

/usr/syno/etc/ups/upsd.users

[monslave]
password = xxxxxx
upsmon slave

Opened port 3493

Included entries in pi upsmon.conf :
MONITOR ups@{syn IP} 0 monslave xxxxxx slave

and hosts.conf:
MONITOR ups@{syn IP} "Synology UPS"

But get "access error"

Any suggestions....

@netboy Synology uses a hard-coded username/password for remote NUT access. You can either use their hard-coded values for monitoring (strongly recommended), or try to hand edit Synology's generated files. Note that if you go the hand-edit route, the files will overwritten by DSM whenever an OS update occurs and you will need to re-edit the files.

@dennypage I used the built in user and configured my raspberry pi upsmon.conf as follows

MONITOR ups@{syn IP} 1 monuser secret slave
[used 1 above ok?]

Tried this as well [ 0 ] with same results.
MONITOR ups@{syn IP} 0 monuser secret slave

Tried pinging from raspberry pi and get the access denied mesg:

root@raspberrypi:/home/piNUT# upsc ups@{syn IP}
Init SSL without certificate database
Error: Access denied

@netboy Never mind was able to mine your forum and I found a post from you here

"egardless of the username/password, if you host on the Synology, you need explicitly list the IP address of pfSense in the list of permitted remote hosts in the Synology (Control Panel -> Hardware & Power -> UPS). This may have been why you were getting permission denied previously."

And now it works!

And now it works!

@dennypage I have to really thank you very much for such quick feedbacks in this forum. I have learned a lots from you and NUT documentation.

Here is my finale!

Need to drink scotch now....Bye

@netboy You’re welcome. Glad you got everything working.
