Most all of the tutorials for this say to use a ESP-01s with a voltage regulator but I Wanted to share a different solution I have found. I had some of these Amazon esp8266 hi let go chips laying around with the added benefit of being able to run on 5v. I found they fit pretty nice if you cut a hole in the top and pass the antenna out. It looks like they don’t obstruct the airflow too much that way. They work great soldered directly to the Ikea board and also work for the constant 3.3v noise hack if you wire the fan positive to the 8266’s 3.3v pin.

    Same thing here. Using ESPHome almost identical config from the tutorial except for my wifi secrets.

    If anyone is interested here is the ESPHome config I arrived on:

    substitutions:
      name: "vindriktning_01"
      friendly_name: "vindriktning 01"
      project_name: "ikea.vindriktning-sensor"
    
    ota:
      password: !secret freindly_password
    
    wifi:
        ssid: !secret wifi_ssid
        password: !secret wifi_password
    
        # Enable fallback hotspot (captive portal) in case wifi connection fails
        ap:
          ssid: "Ikea-Vindriktning-01"
          password: !secret freindly_password
          ap_timeout: 30s
    
    esphome:
        name: "${name}"
        project:
              name: "${project_name}"
              version: "1.0"
    
    esp8266:
      board: esp01_1m
    
    # Enable logging
    logger:
      baud_rate: 0
    
    # Enable Home Assistant API
    api:
    
    uart:
      rx_pin: GPIO2
      baud_rate: 9600
    
    sensor:
      - platform: pm1006
        pm_2_5:
          name: "Particulate Matter 2.5µm Concentration"
    
    web_server:
        port: 80
