Air conditioner Wi-Fi module for Midea, Idea, Neoclima, Electrolux, Beko and many more. 

Model SLWF-01pro (v.1.0)


The WiFi module for air conditioners SLWF-01pro is convenient and easy to use. Also, this module is very functional and versatile. Here are some reasons why you should buy this Wi-Fi module:

  • Ability to work without Home Assistant through a browser (from a smartphone or PC) only in a local network.
  • Compact design, suitable for any conditioners (brands Midea, Idea, Neoclima, Electrolux, Beko)
  • Price: Most modules from other manufacturers usually cost around 800 UAH and do not allow their device to integrate "seamlessly" into smart home systems, but only through their own applications. With this module, you will be able to bypass all such restrictions and conveniently install it into your air conditioner.
  • Alternative choice of chips. A module without expansion and and one  with expansion, ie you will be able to connect other sensors (lighting, sound, motion, temperature and connectors for them)

Worked without any problems! Thanks
The device works, but documentation is very poor for this device. The links to the github repo from the 05/09/2023 FAQ doesn't work as the repo itself does not exist (https://github.com/smlight-dev/slwf01pro-firmware/blob/main/slwf01pro.yaml)
I connected this to my Senville Leto mini split. The USB connector on the mini split has plastic rails left and right of the pins to prevent normal USB connectors from being inserted. I cut the rails away with an Exacto tool so that the SLWF-01 pro could be plugged in easily. Other reviewers mention issues plugging in the module, and I suspect they too were dealing with these rails. The surgery wasn't too difficult, but you will want a sharp blade and your reading glasses. Connecting to my LAN was a easy. Nice instructions. Worked perfectly. My Senville unit is not 100% compatible. The humidity and power sensors in the mini split do not report to HA correctly (they read zero). Maybe there's a fix. Next project is to add a PIR sensor so that I can change the temp. setting when I am actually in the room where the mini split is located.

It was a little stiff to plug in. The first time I tried it wouldn't connect to the mini-split. Then I unplugged it and plugged it back in (after several restarts) and it worked immediately.
Confirmed working on MRCOOL DIY-24-HP-WMAH-230C25
I was going to create the device myself and all, but given the cost of this beauty, I decided to give it s try instead. It works seamlessly in my MrCool 12kBTU mini split! I have to push it hard into the USB female of the unit because it seems to be non-standard, but that was all.

My next question was going to be 'how about updating esphome on it?', and it was quickly solved (see Downloads for the yaml file and the firmware).

Great job, guys! Thank you.

Arrived today and it was very easy to setup, all working fine.
I've Bosch Climate 6000i which has a motion sensor built in, but it hasn't been setup automaticaly on HA. Is there a way to do so?
Thank you!
The administration's response:
Usually, the setting is automatic. If this did not happen, use the instructions for setup that came with the device
