Hi!
<br>
<br>
<blockquote type="cite">I use NUT on Home Assistant, the version
of the add-on is 0.6.2. Home Assistant is installed on a

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.
<br>
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.<br>

It is better to use OL which says that you are receiving utility
power, and therefore charging.
<br>
<br>
<blockquote type="cite">Then OL the normal operation, with a full
battery.
<br>
</blockquote>
<br>
OL should appear before battery.charge = 100%
<br>
</blockquote>
<br>
Nop, "OL" is coming when the battery is fully charged.<br>

I assume you do this by monitoring variable battery.charge.

<br>
Yes.<br>

If you want faster testing, you could also connect a 60W light
bulb.

<blockquote type="cite">Then the battery fell to 48%, and instead
to have OB DISCHRG, I had FSD OB DISCHRG (Fast Shutdown On
Battery Discharge).

<br>
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?
<br>

<br>
I use Network UPS Tools, on Home Assistant (HASS.IO) on a Raspberry
Pi 4.<br>
I don't see any "battery.charge.low"<br>
I don't know for UPSMON.<br>

<blockquote type="cite">Then I re-plugged the UPS to charge it.
<br>
And I was surprised to see FSD OL CHRG until the 100%.
<br>
</blockquote>
<br>
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.
<br>
<br>
<blockquote type="cite">Then, I had FSD OL, even everything was
back and normal, and the battery fully charged.
<br>
<br>
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.
<br>
<br>
<br>
So, I have some questions. I didn't find this kind of
information on internet.
<br>
<br>
- please, could you explain why FSD is coming ? Is it depending
of the load, or the % of battery?
<br>
- Why FSD didn't disappear when the current was back and the
UPS was charging the battery or full?
<br>
- 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).
<br>
</blockquote>
<br>
What do you mean by "mode" ? The possible status symbols, OL, OB,
LB, ...?
<br>
</blockquote>
Yes, status.<br>
<br>
<br>
Thanks for your help :)<br>
