Let me know if you need any other data. IIRC, it sends that info back everytime the ups is polled. battery.capacity: 8 battery.charge: 100.0 battery.charge.low: 25 battery.packs: 2 battery.voltage.nominal: 12 driver.name: powerpanel driver.parameter.pollinterval: 2 driver.parameter.port: /dev/cuad0 driver.version: driver.version.internal: 0.22 input.frequency: 60 input.frequency.high: 63 input.frequency.low: 47 input.transfer.high: 135 input.transfer.low: 88 input.voltage: 121 input.voltage.nominal: 120 output.voltage: 122 ups.firmware: 1.600 ups.load: 6 ups.mfr: CYBER POWER ups.model: BC1200 ups.power.nominal: 1200 ups.realpower.nominal: 720 ups.serial: 000000000000 ups.status: OL ups.temperature: 28 ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program. _______________________________________________ Nut-upsuser mailing list Nut-upsuser@lists.alioth.debian.org http://lists.alioth.debian.org/mailman/listinfo/nut-upsuser
