Add Xiaomi Smart Tower Fan 2 (xiaomi.fan.p45) as unsupported

I opened my Smart Tower Fan 2 model BPTS02DMU (xiaomi.fan.p45) today. It uses a proprietary Wifi module MHCWB5G-B.

Bummer, but thanks for the feedback! I like how the board is labeled though! Nice & hacker-friendly ;)

Just a correction: My device identifies as xiaomi.fan.p45, not dmaker.fan.p45 which has a different spec.
This is the correct spec: https://home.miot-spec.com/spec/xiaomi.fan.p45

But just a bit of incompatible hardware doesn't mean the device won't work with esphome-miot.
I've desoldered the wifi module and wired up an ESP32 C3. Most of the commands are working.

I'm just confused about the Wifi LED which seems to randomly be steady on or fast flashing.

Oh, thanks, I fixed the model id/spec link!

@ccandy79 did you find a module that was pin compatible or how did you wire it in? I've found the same chip in my humidifier.

There are pin compatible modules with an ESP32 C3 available. Have a look into the wiki regarding wiring and programming: https://github.com/dhewg/esphome-miot/wiki/Xiaomi-Smart-Tower-Fan-2

Ohh, thank you!
Just ordered a module from amazon since I'm too impatient for aliexpress right now.
If it works out I'll make sure to also add a page to the wiki for the humidifier.
