Invalid device_classes is an invalid option

[bashers222]

ESPHOME is failing validation of this yaml code immediately:

number.template: [source /config/can-test.yaml:154]
  platform: template
  id: eltek_voltage
  name: Eltek FP2 voltage

  [device_class] is an invalid option for [number.template]. Please check the indentation.
  device_class: voltage
  unit_of_measurement: V
  update_interval: 5s
  restore_value: True
  min_value: 43.5
  max_value: 57.6
  step: 0.1
  optimistic: True
number.template: [source /config/can-test.yaml:166]
  platform: template
  id: eltek_current
  name: Eltek FP2 current

  [device_class] is an invalid option for [number.template]. Please check the indentation.
  device_class: current
  unit_of_measurement: A
  update_interval: 5s
  restore_value: True
  min_value: 0.1
  max_value: 41.7
  step: 0.1
  optimistic: True

Obviously you've got it incorrectly intended. Should be like the one below.

number:
  - platform: template
    id: eltek_voltage
    name: "Eltek FP2 voltage"
    device_class: voltage

sorry, what i meant was I copied the raw code to a brand new vanilla ESPhome YAML (and updated wifi accordingly) But ESPhome thorws an error when it attempts to validate the code as per the repo. What ive added above is the ESPhome output

You're code has the correct indentation, but ESPhome is not happy for some reason and i dont believe its indentation

No idea, compiled without any issue here.

Im running v2022.11.4 and you're on 2023.10.6. Thats probably my first avenue of investigation :)

[bashers222]

yep, that sorted it. sorry to trouble you

Perfect, enjoy that.
