I haven't tried it on RaspberryPi, but if there's some specific Tripp Lite information I can help with, let me know.

After a few hours of working, the service fails. Looking at kernel messages I noticed that the device is repeatedly disconnecting and reconnecting. I have tried using a different USB port and using a brand new USB cable. I have not had success by changing config parameters like pollfreq/pollinterval/etc. What is causing the UPS to keep disconnecting? Not sure (it's a protocol issue lower than NUT), but does this post from Tripp Lite help the UPS automatically reconnect? https://alioth-lists.debian.net/pipermail/nut-upsuser/2019-June/011451.html<https://urldefense.proofpoint.com/v2/url?u=https-3A__alioth-2Dlists.debian.net_pipermail_nut-2Dupsuser_2019-2DJune_011451.html&d=DwMFAg&c=f9s1WCuF-N6cmD_YaZ7gBg&r=lhr3k4au5dVQgHY_iS-v_t9g8PHVkn8Px_wyaupZGfQ&m=5bTj0FByjuC7ZwvwC7XsgqsH_kXRehDbkaYVEGxZrkQ&s=-Pz1JlSeu5vl0n4bXiBIaPW1nFRDro_yq3QvTTbwC5o&e=> (you may need to do some RedHat-to-Debian translation for some of the pathnames.)
