NUT Ups alert: battery needs to be replaced?

All of a sudden my phone got delivered these alerts… Still new to the UPS and NUT (been running it for a week or 2 now).
Which makes the notification all the more remarkable to me. It is a new device, so I wouldnt expect the battery to be in need of replacement at all :wink:

Otoh, the entity does show it is from 2001 ??

Ive considered that a NUT issue, but give the notification now I start to wonder…

Running the default automation(well, after this I now added a timestamp in the message) from the documentation, so at least I am sure now events are emitted, and picked up correctly

  - id: ups_changed_state
    alias: UPS changed state
    trigger:
      - platform: event
        event_type: nut.ups_event
    action:
      - service: notify.mobile_app_me
        data:
          title: UPS changed state
          message: >
            {{now().strftime('%X')}}: {{ trigger.event.data.notify_msg }}
          data:
            push:
              sound:
                name: default
                critical: 1
                volume: 1.0

right, so I returned the device used above, and waited a few months, only to experience a power out the other day…

so, I ordered a new UPS, and lo and behold, within minutes of installing it, the same loggings returned

this must be a fluke, and the first thing I did was edit the automation to Not issue critical warnings on that anymore.

in the device dashboard, the only entity I could find that was out of the regular, was the battery chemistry (sensor.ups_chemie_van_de_batterij in Dutch) having no value/state. I saw it getting back to PbAc later on.

Maybe that is some sort of selftest in the Integration/Add-on.
to be able to what the history of some of the important entities, I now enabled them in the recorder, maybe that will show problems if and when the next notification is issued…

I do see this


but these times dont coincide with any notification I got…
