esphome-config's Issues

on_boot not working

i hope you could help me out.

i liked the setup you use for your devices, so i'm tring to replicate it.
Almost everything is working, but the on_boot event isn't fired and there for i don't get my values from my external memory module.

do you now why on_boot isn't working ?

below, a piece of my code from the device i build.

substitutions:
  system_name: 101-test
  friendly_name: Test
  device_description: "Test sensor to see off all paths are right."
  static_ip: 192.168.1.101

packages:
  device: !include devices/d1_mini.yaml

esphome:
  on_boot:
    priority: 800.0
    then:
      - lambda: |-
          readcounters();
          ESP_LOGI(TAG, "on_boot read");

Hot tub water quality

Capture the following sensor data:

• Temperature (Dallas)
• TDS (ADC)
• pH (ADC)

This is for a jcallaghan/home-assistant-config#12 project.

Hot tub pH sensor

For the pH sensor. Same approach as #4 using ADC.

pH voltage remains constant in every solution and hence pH doesn't change

I am using the hot tub pH sensor code for pH values but the pH doesn't change with the change of solution.
I had also noticed that this is occurring bcoz of the constant pH voltage in every solution. Can someone help me fix this?
