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.

    It is 4x more expensive than the VINDRIKTNING but the newer VINDSTYRKA (Zigbee with a display) setup in seconds and just works via zigbee2mqtt.

    Guess it depends if you have a lot of ESPs kicking around or can get them shipped with all parts and build for low enough / fast enough to justify it.

      I wish either of the IKEA devices measured more. I picked up an Awair Element used off eBay and set it up to provide data locally. The C02 sensor in particular has been really enlightening.

        CO2 would be very useful. I picked up two VINDSTYRKA as I have been concerned about PPM counts in the air as we have a few people with asthma. The VOC reading is kind hard to use in HA as it works against a rolling average and a score in a range.
