Unit ('') does not match

on grouped energy sensors and on all power sensors, this is displayed in the statistics tab of developer

Must admit I didnt see this before, so probably because of updating to latest dev nightly 2022.5.0.dev20220407

I dont have classes set, nor units, believing the powercalc integration handles that?

main config I use is

powercalc:

  energy_sensor_naming: '{} device energy'
  power_sensor_naming: '{} device power'

and eg the groups mentioned are:

  - platform: powercalc
    create_group: Dining table
    entities:
      - entity_id: light.dining_table_lamp_1
      - entity_id: light.dining_table_lamp_2
      - entity_id: light.dining_table_lamp_3


  - platform: powercalc
    create_group: Terrace outdoors
    entities:
      - entity_id: light.terrace_spot_1
      - entity_id: light.terrace_spot_2
      - entity_id: light.terrace_spot_3
      - entity_id: light.terrace_spot_4

as you can see the energy is correctly calculated for the group, its simply a matter of the missing unit

btw, I now notice also, that the grouped sensors dont carry the attribute integration: powercalc, like all other power sensors do. (none of the energy sensors either, is that correct?)

Attribute integration is correct. That one is only set on power entity, not the group ones. Maybe I’ll will remove that one in the future as I only added it to make groups with the template sensor (and only select powercalc sensors that way). However since the last months powercalc has extensive possibilities to create groups, so this attribute is obsolete. But it certainly has nothing to do with the missing unit.

I have no clue yet, must be something HA internal.

When you still experience this issue in the coming week (when 2022.5 is progressing) I will have a look if I can reproduce.

Btw, here are the units set. This is according to HA developer documentation, and has always worked.

cool, and thanks! fwiw, I asked in #dev_energy, but no response just yet

I have already made the change in #670. Has been merged into master.

Omt: since I had debug level on, I noticed that the Hue sensors keep switching from on/off to unavailable a lot in the powercalc feedback. The new core Ha integration follows the v2 api, and I must confess those connection issues have become more and more prominent.

I don’t think I am experiencing this issue. I have one light which gets unavailable sometimes (not sure why), but my other 22 lights are rock solid and never get unavailable. Also had this issue with the V1 api for that particular light. So I am not sure why you are experiencing an regression here with Hue API V2.

This is not something which can be solved in powercalc as I just act on state changes of the bound entity. When there are bugs in the hardware / api / integration (in this case Hue) it has to be solved there.
