Request for Esphome Code

[richardholst]

Hi there,

I am working on a simular project to your esphome IOT Air Freshener ..I am sort of merging your project and another project (https://www.instructables.com/IoT-Air-Freshner-with-NodeMCU-Arduino-IFTTT-and-Ad/) into one and I am having a real hard time to get my esp code to work ...I like to use esp32 for projects but have 1 or 2 esp8266 around which I am trying now ..

But I was hoping to get a look at your code to see where I might be going wrong ...

cheers Richard

I ended up creating my own, using:

• ESP32 Wroom DevKit
• 5v Relay
• 2x 18650 battery case
• Bunch of jumper wires
• ESPHome
• USB-A Male - Micro USB Male -cable

The schema I used was slightly different than the one used here: https://jcallaghan.com/2020/03/can-you-iot-an-airwick-air-freshener/

Also, difference to the article mentioned above: my AirWick had 1.5V motor, therefore I ended up using the original battery case for the motor.

The connection schema is as following:

• 18650 Battery Case USB-A -> ESP32 microUSB

• ESP32 GPIO 21 Pin -> Relay S (the left one)

• ESP32 5V Pin -> Relay Positive (the middle one)

• ESP32 GND Ping -> Relay Minus (the right one)

For the motor I did the following:

• Minus from the original battery case -> Motor Minus
• Plus from the original battery case -> To Relay middle
• Plus from Relay NO (Normally Open) -> Motor Plus

The ESPHome configuration looks like this:

esphome:
  name: airwick-hallway
  platform: ESP32
  board: esp-wrover-kit

wifi:
  ssid: !secret wifi_ssid
  password: !secret wifi_password
  # Uncomment the following line if renaming the node
  # use_address: airwick-hallway.local
  use_address: 192.168.1.126

  # Enable fallback hotspot (captive portal) in case wifi connection fails
  ap:
    ssid: "AirWick Hallway Fallback"
    password: "fallback Passw0rd"

captive_portal:

# Enable logging
logger:
 level: DEBUG

# Enable Home Assistant API
api:

ota:

switch:
  - platform: gpio
    pin:
      number: 21
    name: "AirWick"
    id: airwickHallway
  - platform: restart
    name: "AirWick Hallway Restart"
    id: airwickHallwayRestart
  - platform: template
    name: "AirWick Hallway Switch"
    id: airwickHallwayTemplate
    icon: "mdi:air-horn"
    turn_on_action:
    - switch.turn_on: airwickHallway
    - delay: 1s
    - switch.turn_off: airwickHallway

mqtt:
  broker: !secret mqtt_broker
  discovery: True
  username: !secret mqtt_user
  password: !secret mqtt_password
  topic_prefix: "airwickHallway"
  on_message:
    - topic: "airwickHallway/trigger"
      then:
        - switch.turn_on: airwickHallwayTemplate

Additionally I created one automation with 3 different conditions, few Input Datetimes for the intervals and this panel:

My automation is as following:

- id: hallway_airwick_intervals
  mode: restart
  alias: AirWick hallway - Intervals
  trigger:
    - platform: time_pattern
      minutes: "*"
  action:
    - choose:
        - conditions:
            - condition: template
              alias: "No movement in Hallway and frontdoor closed"
              value_template: "{{ is_state('group.hallway_motion_door', 'off') }}"
            - condition: template
              alias: "Status - Someone Home"
              value_template: "{{ is_state('group.all_tracker_devices', 'home') }}"
            - condition: template
              alias: "Last time activated more than defined interval (in this example 30 minutes)"
              value_template: "{{ as_timestamp(state_attr('script.hallway_press_twice', 'last_triggered')) < (as_timestamp(now()) - as_timestamp('1970-01-01T' + states('input_datetime.airwick_hallway_status_home_interval') + 'Z')) }}"
          sequence:
            - service: script.hallway_press_twice
        - conditions:
            - condition: template
              alias: "No movement in Hallway and frontdoor closed"
              value_template: "{{ is_state('group.hallway_motion_door', 'off') }}"
            - condition: template
              alias: "Status - No One Home"
              value_template: "{{ not is_state('group.all_tracker_devices', 'home') }}"
            - condition: template
              alias: "Last time activated more than defined interval (in this example 1 hour)"
              value_template: "{{ as_timestamp(state_attr('script.hallway_press_twice', 'last_triggered')) < (as_timestamp(now()) - as_timestamp('1970-01-01T' + states('input_datetime.airwick_hallway_status_away_interval') + 'Z')) }}"
          sequence:
            - service: script.hallway_press_twice
        - conditions:
            - condition: template
              alias: "No movement in Hallway and frontdoor closed"
              value_template: "{{ is_state('group.hallway_motion_door', 'off') }}"
            - condition: template
              alias: "Status - Everyone Sleeping"
              value_template: "{{ is_state('binary_sensor.everyone_home_sleeping', 'on') }}"
            - condition: template
              alias: "Last time activated more than defined interval (in this example 2 hours)"
              value_template: "{{ as_timestamp(state_attr('script.hallway_press_twice', 'last_triggered')) < (as_timestamp(now()) - as_timestamp('1970-01-01T' + states('input_datetime.airwick_hallway_status_sleep_interval') + 'Z')) }}"
          sequence:
            - service: script.hallway_press_twice

The script used in the automation:

hallway_press_twice:
  alias: hallway - Press twice
  mode: restart
  sequence:
    - service: switch.turn_on
      data:
        entity_id:
          - switch.airwick_hallway_switch

The Input Datetimes:

airwick_hallway_status_home_interval:
  name: AirWick hallway - Home Interval
  icon: mdi:home
  has_date: false
  has_time: true

airwick_hallway_status_away_interval:
  name: AirWick hallway - Away Interval
  icon: mdi:home-import-outline
  has_date: false
  has_time: true

airwick_hallway_status_sleep_interval:
  name: AirWick hallway - Sleep Interval
  icon: mdi:sleep
  has_date: false
  has_time: true

The automation tries to trigger once per minute, if any of the conditions are met. Description for the automation conditions:

• If there is no motion detected in the hallway, the front door is closed, at least someone is home, the script was last triggered more than the defined interval ago (in this case 30 minutes)
• If there is no motion detected in the hallway, the front door is closed, no one is home, the script was last triggered more than the defined interval ago (in this case 1 hour)
• If there is no motion detected in the hallway, the front door is closed, everyone (that are home) are asleep, the script was last triggered more than the defined interval ago (in this case 2 hours)

The panel shows the last time the script was triggered and also contains a button for manually triggering the script (it don't have any conditions, therefore you can push it as many times as you wish the AirWick to run)

Configuration for the panel:

Can you IoT an Airwick air freshener?

This project is one that makes me feel on top of the world but also possibly one of my most craziest IoT projects. I am fascinated with IoT and the point where software interacts with my physical w…
