hi,

i recently bought an "EATON Ellipse PRO" that is recognized by the
upd(4) driver, thus i get some sensors, but some are off (RunTimeToEmpty
says 200000s while the LCD says '15mn'..) and some are missing.

i looked at the lsusb -vv output and my model supports more sensors from
the usb hid power/battery usage page specs.

defining UPD_DEBUG now gives me this:

upd: vendor=0x0463, product=0xffff
upd0 at uhidev0
upd: devname=upd0 sc_max_repid=256
upd0: found RemainingCapacity on repid=6
upd0: found FullChargeCapacity on repid=12
upd0: found PercentLoad on repid=7
upd0: found ActivePower on repid=14
upd0: found ConfigApparentPower on repid=13
upd0: found ApparentPower on repid=14
upd0: found VoltageDc on repid=14
upd0: found Charging on repid=1
upd0: found Discharging on repid=1
upd0: found RunTimeToEmpty on repid=6
upd0: found NeedReplacement on repid=1
upd0: found ShutdownImminent on repid=1
upd0: found ACPresent on repid=1
upd0: found Overload on repid=1
upd: sc_num_sensors=14

but from all those, some are either garbage values, or i didnt find yet
the right scale/multiplier/exponent/unit..

just showing the 'new ones' added by the below diff:

hw.sensors.upd0.volt0=878.40 VDC (VoltageDc), OK
hw.sensors.upd0.power0=878.40 W (ActivePower), OK
hw.sensors.upd0.power1=2340.00 W (ConfigApparentPower), OK
hw.sensors.upd0.power2=0.00 W (ApparentPower), OK
hw.sensors.upd0.percent2=30.00% (PercentLoad), OK
hw.sensors.upd0.timedelta0=674.049600 secs (RunTimeToEmpty), OK

PercentLoad matches what the LCD says, so for this one it seems correct.

for the others, the values don't make sense/dont match what the LCD
says, and as soon as i add too many sensors, i get this in dmesg:

uhid29 detached
hotplug: event lost, queue full
uhidev0 detached
hotplug: event lost, queue full
uhidev0 at uhub0 port 2 configuration 1 interface 0 "EATON Ellipse PRO" rev 1.10/1.00 addr 2

so something detaches/reattaches upd ? is that something to worry about?

as for RunTimeToEmpty, i found out that throwing 60*60 to the scaling
value gives me a value that matches what the lcd says, as 'systat
sensors' shows (converts secs to mins/hours):

upd0.percent2       20.00%    OK PercentLoad
upd0.timedelta0 19.344 min    OK RunTimeToEmpty

but ofc i dunno if that's a quirk of my model or something else..

so if you have an upd(4) somewhere and you have sensors, i'll be glad to
know if:
- you get more sensors and they make sense
- you get values that make more sense than before
- you had a value for RunTimeToEmpty that made sense and now doesn't
  (same for AtRateTimeToEmpty/AtRateTimeToFull if you have them)
- it now breaks/detaches/reattaches

with the attached diff.

help welcome on the units/scaling bits, the reference spec i found so far was
https://www.usb.org/sites/default/files/documents/pdcv10.pdf - i havent
tried with linux/nut yet.
