Made good progress and managed to run working ESPHome configuration on the fan. So chances significantly increased that you can do the same for the DreamMaker model.
I had problems with my Dream Maker fan a few days ago because it was unable to connect to the DM servers.
This has made me take up again the project that “direx” mentioned called dmio2mqtt (abandoned since almost 3 years ago), I have updated it to adapt it to docker, to use a device id instead of the IP in the mqtt topics and what I consider the most comfortable of all, I have added compatibility with the MQTT Discovery of Home Assistant.
I bought a DM-FAN01 and it came with a Tuya WBR3 chip in it. I’m not sure whether to be happy or sad. I was looking forward to it having an ESP chip in it and using esphome-miot or the MQTT solution. But it does work great in Tuya Local or Local Tuya. I might swap it out with an ESP32-C3-12F at some point as it’s pin compatible.
