HX711 is not ready for new measurements yet!

ESPHome
1

I inadvertently messed some things up on my network and didnt have a backup, so I had to rebuild some of my ESPhome items by scratch. This was just working the other day, so I know the hardware is still good. I loaded an old bin and saw the scale device was returning results.

I’m running ESPhome as a docker container, so I’m not using the internal version. This device is another “bed scale” type. My yaml:

esphome:
  name: mbr-bed-hx711
  friendly_name: mbr-bed-hx711
  includes:
    - "custom_hx711.h"
  libraries:
    - "https://github.com/bogde/HX711"

Is the update too fast at every 1/2 second, default is 60 seconds. The only difference with your config and mine is the gain is 64 and a 30 sec update time. Are you sure about the pin assignment having lost the original sketch?

3

Fairly sure. Would you mind sharing your yaml so I can run a diff on my end?

I commented out the filters. They are for calibration and to change the weight to gallons, it’s not needed for setup.

  - platform: hx711
    name: "grow_res_level"
    dout_pin: GPIO14
    clk_pin: GPIO12
    gain: 64
    update_interval: 30s
    # filters:
    #   - calibrate_linear:
    #     - -8800 -> 0
    #     - 46458 -> 10
    #     - 98943 -> 20
    #     - 156723 -> 30
    #     - 210661 -> 40
    #     - 237000 -> 50
    #   - quantile:

    #   - lambda: return x / 8.345;
    # unit_of_measurement: gal
    accuracy_decimals: 3

Thanks, but could you share the entire yaml, redacted where appropriate? I’m having a day with this and want to make sure bits 100%

Thank you so much… at least I have something compiling now. That’s quite a sensor you created! What’s it for?

ETA: Still getting the same error with your code. Fudge

It’s for a grow tent. Double check your wiring, if it works with an old sketch, it would seem the pin assignments are wrong.
