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.

    You could also get a d1 mini. That’s what I used it’s smaller and doesn’t come with the pins soldered on. It also has a 5V in. What are you using to bring the data into HA? I used esphome.

      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
