[Nut-upsuser] Adding support for NUMERIC UPS

[Holla]

Hi,

I have been blessed with the "Numeric 2000 Plus" UPS, suspected to be of
2KVA rating. This UPS does not figure in the list of UPS recognised by NUT.
However I get lucky with megatec driver.

Here is the log...

Following the mailing list, I did the "full charge/discharge" to
tackle the unsupported combination of battery situation

Then I added the following lines to the ups.conf

[Numeric]
        driver = megatec
        port = /dev/upslink
        desc = "Numeric 2000 LI"
        battvolts = 30.4:41.0
        lowbatt = 25

Now "upsc Numeric" command returns the following:


$ upsc Numeric
battery.charge: 100.0
battery.voltage: 41.00
battery.voltage.nominal: 36.0
driver.name: megatec
driver.parameter.battvolts: 30.4:41.0
driver.parameter.lowbatt: 25
driver.parameter.pollinterval: 2

input.voltage.fault: 210.1
input.voltage.maximum: 213.1
input.voltage.minimum: 208.6
input.voltage.nominal: 230.0
output.voltage: 209.0
ups.beeper.status: enabled

ups.mfr: NUMERIC
ups.model: 2000 Plus VER 40643N
ups.serial: unknown
ups.status: OL
ups.temperature: 40.0
ups.type: standby


Is this all that needs to be done for an unspported UPS ?

Just running the NUT-monitor app, I noticed that the "Time Remaining"
info is not available. Does this look OK ?
