The override.* settings can cover both cases. If you just provide override.battery.runtime.low, you are just replacing what is sent from the driver to upsd, and then on to clients like upsc. (In particular, this doesn't send any settings adjustments back to the UPS.) Since upsmon is watching ups.status for the UPS-provided LB bit (by default), this isn't sufficient to modify shutdown behavior. The subtle difference in examples like this: https://alioth-lists.debian.net/pipermail/nut-upsuser/2020-August/011977.html is the use of "ignorelb" in concert with "override.battery.runtime.low". I also ran across this thread while looking up info on the BR1500GI: https://alioth-lists.debian.net/pipermail/nut-upsuser/2020-November/012172.html I don't think we resolved the shutdown issue (or got debug logs to dig deeper). > > Required information: > > OS: Linux **** 5.4.83+ #1379 Mon Dec 14 13:06:05 GMT 2020 > armv6l GNU/Linux > NUT version: 2.7.4-8 > NUT installation: package > UPS: APC BR1500GI Thanks, appreciate the info! > > Thanks. > _______________________________________________ > Nut-upsuser mailing list > Nut-upsuser@alioth-lists.debian.net > https://alioth-lists.debian.net/cgi-bin/mailman/listinfo/nut-upsuser _______________________________________________ Nut-upsuser mailing list Nut-upsuser@alioth-lists.debian.net https://alioth-lists.debian.net/cgi-bin/mailman/listinfo/nut-upsuser
