Re: SLWF-01pro Midea Wi-Fi Module
the picture with the USB adapter is inside my AC. I think that inside that USB adapter is the SLWF-01pro stick model, because my AC unit work in Home Assistant whit midea integration.

Re: SLWF-01pro Midea Wi-Fi Module
Okay, here is the little tutorial:
I'm using a Odroid with Linux and HomeAssistant, but you can use an VM or raspberry as well.
(We just need just HomeAssistant for compling the firmware)
First start with HomeAssistant and install ESPHome over there.
After you installed ESPHome, add a new device >
Call it Airco (for example) and click next > After that choose the esp8266 board > Then skip the key (since we do not need it because no homeassistant is using)

Re: SLWF-01pro Midea Wi-Fi Module
Great, your first device is made.. >
DO NOT forget to:
make your own unique name and so change the roomairco to the name of your device.
also do not forget to setup the mqtt broker to the ip or hostname of your mqtt broker, otherwise it will not work
Then click on edit: >
After that use this YAML and make changes to your own settings.:
Code: Select all
esphome:
name: roomairco # Give your device a main-name
platform: ESP8266
board: esp12e

# Enable fallback hotspot in case wifi connection fails

Re: SLWF-01pro Midea Wi-Fi Module
Then we going to compile the code into firmware by doing save > install > manual download > modern format:

Re: SLWF-01pro Midea Wi-Fi Module
After compiling you will get the .bin file to upload to the usb-stick you did recieve. >
Put in the usb-device into an USB-Port or the usb into your HVAC device itself, and go to your wi-fi list
after some 20/30 seconds you will see an open ssid network with openesp, connect to it.
then you be asked to connect the usb-device to your network
then connect the usb-device to your wi-fi network then it will get an ip address to connect to.
search the ipaddress of your usb-device on your network and open it in your browser
(example: http://192.168.1.50/) and upload the firmware you just made to your usb-device: >
After that, go into your Domoticz and add new hardware (if not done already) > MQTT AutoDiscover
Domoticz does search for all HomeAssistant MQTT devices and will add them automatically.
When everything is finished, your device should appear in to Domoticz after MQTT AutoDiscover finished his job..
Happy automation
