I recently installed a Forza UPS to the NUT add-on. Had a little trouble setting up the configuration, but it ended up working. I am posting this in case it may help somebody.
My specific UPS was a Forza SL-801UL
And the configuration of the devices section of NUT:
- name: forza
driver: nutdrv_qx
port: auto
config:
- override.battery.packs = 1
- default.battery.voltage.nominal = 12
- default.battery.voltage.high = 13.47
- default.battery.voltage.low = 11.0
- runtimecal = 180,100,480,50
- chargetime = 14400
- idleload = 2%
the blazer_ups driver did not work for me.
