Hi :)
Hi!
I use NUT on Home Assistant, the version of the add-on is 0.6.2. Home
Assistant is installed on a Raspberry Pi 4b.
A have a APC 1400, the UPS is connected with USB to the Rasp.
I'm working to built an automation, to receive notifications when
there is a power cut.
So I used OB DISCHRG (On battery discharge) to detect the power cut
and trigger the automation.
It is sufficient to use OB. Not all UPS's show DISCHARG
Ok.
Then I use OB CHRG to detect that the power is coming back and the
battery is charging.
It is better to use OL which says that you are receiving utility
power, and therefore charging.
Then OL the normal operation, with a full battery.
OL should appear before battery.charge = 100%
Nop, "OL" is coming when the battery is fully charged.
In the same time I send notification to follow the % of battery (97 >
93 > 90 etc). It's working.
I assume you do this by monitoring variable battery.charge.
Yes.
During my real test, the load was to light (3%, only a rasp pi), so
it was slow to empty the battery. So I connected and started my main
PC, than the load was 18%.
If you want faster testing, you could also connect a 60W light bulb.
Then the battery fell to 48%, and instead to have OB DISCHRG, I had
FSD OB DISCHRG (Fast Shutdown On Battery Discharge).
What is the value of battery.charge.low in your setup? It is
surprising to see FSD appear with no LB status. Do you have upsmon
running? What is your system shutdown criterion in upsmon? Do you
rely on the built-in emergency shutdown on OB LB?
I use Network UPS Tools, on Home Assistant (HASS.IO) on a Raspberry Pi 4.
I don't see any "battery.charge.low"
I don't know for UPSMON.
Then I re-plugged the UPS to charge it.
And I was surprised to see FSD OL CHRG until the 100%.
FSD is held fixed in upsd. upsd does not turn it off, since it is
assumed that there will be a system shutdown followed by a system
restart which clears ups.status.
Then, I had FSD OL, even everything was back and normal, and the
battery fully charged.
I saw today, few days later, than now it's only OL (Online). I
imagine that FSD disappeared after a reboot or when I disconnected
some USB cables.
So, I have some questions. I didn't find this kind of information on
internet.
- please, could you explain why FSD is coming ? Is it depending of
the load, or the % of battery?
- Why FSD didn't disappear when the current was back and the UPS was
charging the battery or full?
- Is there a list of all "modes" that NUT can show? (because my
automation didn't work any more when FSD appeared, so I would like to
know all modes).
What do you mean by "mode" ? The possible status symbols, OL, OB, LB,
...?
Yes, status.
Thanks for your help :)
Roger
