Use input_number-entity

[KayGundhardt]

Hi! Congrats to this awful HA integration!! :) What about changing the spools weight sensor-entity into an input_number-entity? This way HA automations could write information into the input_number entity (e.g. get the actual "live mass" from a scale under a reel).

Thank you for this feature request!

Could you please write more about that feature request? I would know how would your workflow will be.

Should the values be saved into the appropriate spool in spoolman or only in HA?

Hi Marco!

Sure, of course: all my filament rolls are each on an HX711 load cell which are connected to the HA via several ESPs (example pic can be found below). The empty roll weight and the other dead weight are now subtracted from the measured mass and then converted and written into the "pure roll mass" (an input_number-entity) using an HA automation (yaml see below). If your plugin could now write this "live mass" to the spoolman, there would be no need to manual enter the values anymore...

I hope I was able to explain it in an understandable way? :))

- service: input_number.set_value
  entity_id: input_number.pla_schwarz_form_futura_masse
  data_template:
    value: >-
      {{ ( states('sensor.scale7_masse') | float) - (
      states('input_number.pla_schwarz_form_futura_leerrollenmasse') | float)}}

Neat setup! I really love the usage of the esps and the load cell. Great work!

Thank you for your explanation. I will think about this and find a way to implement this without scrambling up all created entities.

Actually I’m pretty torn about this since this is a pretty unusual use case. But let me sleep on it for a few nights. Can’t promise if I’m implementing this at the moment.

besides that: do you use some Klipper compatible printer? If yes you can automatically report the spool usage to spoolman from Klipper.

Sure - I'm grateful for anything you can do; and maybe that's just sleeping on it. In any case, I'm glad you're taking the time to think about it!

:)

And as for Klipper: my MK3 runs his old marlin :) I don't dare to experiment...
