Combine 3 sensors to one (ESPHOME)

ESPHome
1

Hello,

I want be able to monitor my Windows in my home. I have 11 windows and the status of the windows can be:

  • Closed
  • Open
  • Tilted

I am now making a PCB with 3 reed sensors, ill print a mount with a magnet so when the handle is turned between the 3 options the reed switch will trigger a esp32.

At this point my setup works, but i have 3 sensors for 1 window.

In the end i would like to have one Sensor (published) like:

Kitchen Window: Open/Closed/Tilted.

The code i have been using so far:

binary_sensor:

  - platform: status
    name: "hs-sb-window-4"

  - platform: gpio
    pin: 4
    name: "Raam Closed"
    device_class: window

  - platform: gpio
    pin: 2
    name: "Raam Tilt"
    device_class: window

  - platform: gpio
    pin: 35
    name: "Raam Open"
    device_class: window


sensor:
  - platform: adc
    pin: 32
    name: "Voltage"
    update_interval: 60s
    attenuation: auto

deep_sleep:
  run_duration: 10s
  sleep_duration: 10min
  esp32_ext1_wakeup:
    pins:
    - 4
    - 2
    - 35
    mode: ALL_LOW

I hope anyone here has some good information :), i cant find it so far!

Maybe what you want can be achieve with a template text sensor

Something more or less like this might work? The Mijn Raam sensor should expose the three string values depending on the magnets that get triggered. (You might need to debounce the signal if you use reed contacts, maybe not)

text_sensor:
  - platform: template
    name: "Mijn raam"
    id: template_text

- platform: gpio
    pin: 4
    name: "Raam Closed"
    internal: true
    on_press:
       then:
        - text_sensor.template.publish:
               id: template_text
               state: "Closed"

  - platform: gpio
    pin: 2
    name: "Raam Tilt"
    internal: true
    on_press:
       then:
        - text_sensor.template.publish:
               id: template_text
               state: "Tilt"

  - platform: gpio
    pin: 35
    name: "Raam Open"
    internal: true
    on_press:
       then:
        - text_sensor.template.publish:
               id: template_text
               state: "Open"

Thanks! That did the trick!

text_sensor:
  - platform: template
    name: "Test raam"
    id: template_text

binary_sensor:

  - platform: status
    name: "esp-testraam"

  - platform: gpio
    pin: 4
    name: "Raam Dicht"
    on_press:
       then:
        - text_sensor.template.publish:
               id: template_text
               state: "Dicht"


  - platform: gpio
    pin: 2
    name: "Raam Tilt"
    on_press:
       then:
        - text_sensor.template.publish:
               id: template_text
               state: "Tilt"

  - platform: gpio

if you can use an input select (helper) with “raam x status” --.> dicht, gekanteld or open (english closed,tilted or open) and have an automation change the state of the helper reflecting the setting.

if this works you can list only 11 (1 per window)
