Overview

I ran into some issues with NUT and my new Tripp Lite SMART1500LCDXL and wanted to post me notes so others can benefit.

Issue

MUT would post a wall message stating that it lost connection with the UPS and then post that the data was stale.

Resolution

I initially set the pollinterval to 15 seconds, but started getting the disconnect issue. It turns out that the UPS likes to be polled by the driver every 1/2 second. NUT by default sets a 'pollinterval' of 2 seconds which seems to be frequent enough to prevent the disconnect. So I just commented out the pollinterval line in ups.conf, you could set it to a value of 1 but 2 seems to be enough.

ups.conf

[ups1]
        driver = "usbhid-ups"
        port = "auto"
        desc = "Tripp Lite SMART1500LCDXL"
        vendor = "Tripp Lite"
        vendorid = "09ae"
        productid = "2012"
#       pollinterval = 1
        bus = "001"
