Jeez. I've had a Coway for about eight years, such a good device that my whole perception was “good product == good company”. If I had known their IOT offering was such a POS I would think very differently.
That said, the non-wifi model works perfectly with a simple HomeKit compatible on/off plug, so all this work — despite being very, very cool — seems a little pointless?
Can't crank up the fan with an on/off plug.
