What am i doing wrong in ESPHome (Sensor Conversions)

what am i doing wrong here,

sensor:
  - platform: hx711
    name: "Scale A g"
    id: "SAg"
    dout_pin: GPIO4
    clk_pin: GPIO5
    gain: 64
    update_interval: 1s
    filters:
      - calibrate_linear:
          - -10000 -> 0
          - -11567 -> 1000
    device_class: "weight"
    state_class: "measurement"
    unit_of_measurement: g
    icon: mdi:scale
    accuracy_decimals: 1
    internal: false
    
  - platform: hx711
    name: "Scale B g"
    id: "SBg"
    dout_pin: GPIO12  
    clk_pin: GPIO14
    gain: 64
    update_interval: 1s
    filters:
      - calibrate_linear:
          - -10000 -> 0
          - -11567 -> 1000
    device_class: "weight"
    state_class: "measurement"
    unit_of_measurement: g
    icon: mdi:scale
    accuracy_decimals: 1
    internal: false

  - platform: template
    name: "Scale A kg"
    id: SAkg
    lambda: |-
      return id("SAR") / 1000.0;
    update_interval: 5s
    device_class: "weight"
    state_class: "measurement"
    unit_of_measurement: kg
    icon: mdi:scale
    accuracy_decimals: 3
    internal: false

  - platform: template
    name: "Scale B kg"
    id: SBkg
    lambda: |-
      return id("SBR") / 1000.0;
    update_interval: 5s
    device_class: "weight"
    state_class: "measurement"
    unit_of_measurement: kg
    icon: mdi:scale
    accuracy_decimals: 3
    internal: false

the Scale A/B kg just show 83 (statically) , where as the Scale A/B g shows correctly and changes

no logs - no issue

As my signature says- I am no expert. But, where are “SAR” and “SBR” defined? Shouldn’t that be “SAg” and “SBg”?

so this is the full config, i did notice a couple of typos which have been fixed and it still does not play nicely.

the kg still isn’t showing correctly.

in terms of compilation errors there are none, but the return id(“SBg”) dosen’t appear to pull the g value.

You want:

    lambda: |-
      return id(SAg).state / 1000.0;

jonathan3 · January 3, 2025, 11:18am

that gives me compilation errors.

/config/esphome/-test.yaml: In lambda function:
/config/esphome/-test.yaml:82:24: error: request for member 'state' in 'esphome::id<const char>(((const char*)"SAg"))', which is of non-class type 'const char'

Look again at my code. No quotes around SAg.

Please format logs, code etc correctly using the </> button to avoid destroying quotes and indentation, like you did in your original post.

jonathan3 · January 3, 2025, 11:25am

Thank you, I’m sure i’d tried that last night though it was very late

Go back and edit your post with code tags. We can’t read your configuration until you do.
