How to pass a user value?

[zix]

This code works with static “- above:” and “- below: 70.0” values. I want to pass the value “Set Temp” from the web ui .

esphome:
  name: temp-led
  friendly_name: temp-led

esp8266:
  board: d1_mini

# Enable logging
logger:

# Enable Home Assistant API
api:
  encryption:
    key: "xxx"

ota:
  password: "xxx"

wifi:
  ssid: !secret wifi_ssid
  password: !secret wifi_password

  # Enable fallback hotspot (captive portal) in case wifi connection fails
  ap:
    ssid: "Temp-Led Fallback Hotspot"
    password: "xxxx"

i2c:
  scan: true

sensor:
  - platform: sht3xd
    temperature:
      filters:
      - lambda: return x * 1.8 + 32.0;
      unit_of_measurement: "°F"
      name: "Temperature"
      id: temp_led_temperature
      on_value_range:
        - above: 70.0
          then:
            - light.turn_on: led
        - below: 70.0
          then:
            - light.turn_off: led

    humidity:
      name: "Humidity"
      id: temp_led_humidity
      
    address: 0x44
    update_interval: 60s


light:
 - platform: status_led
   name: "LED Output"
   pin: D7
   id: led

number:
  - platform: template
    name: "Set Temp"
    id: newtemp
    mode: slider
    optimistic: true
    step: 1

Hello and welcome to the forum.

How to format your code in forum posts

Spaces at the beginning of the line are critical in yaml, and people trying to help you may want to copy your code so that they can try it out themselves, so please format it correctly when you are posting. Use the preformatted text tool (</> in the edit post toolbar). If it is not immediately visible, it will be in the cogwheel menu. [Code_format] Alternatively you can use three backticks (the key is on the far left, 2nd row on en keyboards) on their own line above and below the code. That i…

It doesn’t make sense to take a look at the code you posted, as it could simply be wrong by formatting.

Please post the code properly formatted, so we can help you! Thanks!

Thanks, Sorry about that. This is my first post. I re-posted the code.

[paddy0174 (Patrick)]

Not a problem, but the code is still not properly formatted.

Take a look at the link I posted above, there it is explained, why formatting matters very much, and how to format the code correctly to show here in the forum.

[zix]

Thanks again. I think, I think is now properly formatted.

@zix

I think is now properly formatted.

Just to be sure, we’re talking about the HA dashboard you showed in your second picture, right? So you want to set the temp in your dashboard and your ESP should work with that?

If so, you’d need to import the value from HA via the sensor component in ESPHome, see here:

Home Assistant Sensor

I’m not 100% sure that the “below” field is templatable, but I think so.

Let me know if it works for you!

Unfortunately on_value_range and similar stuff accepts only fixed value.
Use on_value with lambda and write code You want like:

- platform: sht3xd
  ...
  on_value:
    - lambda: |-
        if (x>id(newtemp).state) { id(led).turn_on(); } else { id(led).turn_off(); }

[paddy0174 (Patrick)]

Thanks for the clarification, I wasn’t sure.

[Masterzz (Igors Micko)]

Another way is to use binary_sensor - I like it, actually.

binary_sensor:
  - platform: template
    id: bs_newtemp
    lambda: return (id(temp_led_temperature).state > id(newtemp).state);
    on_press:
      - light.turn_on: led
    on_release:
      - light.turn_off: led

You can use binary_sensor in frontend, add more conditions to it lambda, as well it leads to less operations with led - will turn on/off only on transition, not on every temperature reading. It is not a big, but overhead. IMHO.

thanks very much all. I finally did it and working… For all new coders below is my final version of my yaml.
