Anyone Integrated a Mr. Cool Ductless w/ WiFi?

[vilord (Jesse Campbell)]

Did a little more digging, and it appears that the Mr. Cool units are rebranded Midea ACs (there are a half dozen brands that all use Midea… this is true for microwave ovens as well).
I’m going to give this project a try, since I already have a bag of spare ESPs.
But the short version is that apparently (if the above and linked information is accurate) the USB dongle doesn’t actually talk USB… it talks 9600 baud 5v serial over the USB pins.

I’ve been asked to secure this info from Any Support for Midea A/C I’ve put here all relevant info from that topic: [image] Looks like it is finally working! Thanks Mac-Zhou, ReneKlootwijk, SergeyDudanov, Fraschi for awesome collaboration. (it already works, but development still ongoing to support more models and functions) See this post for supported models (list is updated regularly) Thanks @paddy0174 !! Hardware: You can either order them online (pre-assembled, have a look here Than…

well…to be specific, usb is a universal serial bus…but this dongle uses RS-232 over an usb connector

[vilord (Jesse Campbell)]

Yes, what you said

[vilord (Jesse Campbell)]

Following up, this ^^ works great with the Mr. Cool’s.

Has anyone worked on getting this working? I have two units and would like to get them integrated.

Willing to help out in any way.

[aceindy]

yes…confirmed by vilord in message above yours:

@vilord

this ^^ works great with the Mr. Cool’s.

I can confirm it works with Mr. Cool units. Ill post some picture of the units tmrw. This is really awesome thanks so much!

[rabittn (Ryan)]

I was hoping via their api. Might have to go the esp route.

[aceindy]

I’m getting mixed things about that…
osk102 seems to work occasionally, osk103 works almost…never…
need fake cloud and stuff like that…
Then some updates from cloud breaks it again…

So I would recommend the esp way…cheap, reliable and relative easy, especially now pull-request request for midea-protocol from Sergiy is merged into esphome repository

I have a Mr Cool unit as well (installed several weeks ago). Tried homebridge-smartcielo and it never worked for me.

I cannot control it properly from homebridge, let alone home assistant. None of the controls work (temperature or power on).

[aceindy]

The combination of homeassistant and esphome module works…

Hey guys! I’ve been waiting for a solution on this one for a while now- reading through, it sounds like you’ve finally cracked it! My background here is very limited, but I’m a snappy learner! Would you mind breaking down the ESP method so that I can finally get my Mr Cools in HA?

Super grateful for your time!

Wow just came across this thread, This seems promising that this Integreation of Cielo Smart AC controller will work. Thank you for creating this.

Do you know if this can say work with some temp sensor.

I have a server rack and ac in the room. Or Pioneer Mini Split AC with Cielo smart AC app on the phone.

I am wondering say if I put some temp sensor in the rack and rack say reaches 95F then AC should come on when it reaches say 70 Degree or what ever temp AC turns off…

Anyway regardless thank you so much for creating this.

[cowboysdude (John Wade)]

Yes the Cielo will work, I was using it however it was limited sooooooooooo I went this route…

Sensibo Integration

Sensibo

First in my Configuration yaml:

#Air Conditioner
  - platform: sensibo
    api_key: !secret ac_key

Then in my lovelace.yaml

 - type: custom:simple-thermostat
          entity: climate.john_s_device
          name: false
          decimals: 0
          step_size: 1
          sensors:
            - entity: sensor.thermostat_relative_humidity_measurement
              name: House Humidity
              decimals: 0
            - entity: sensor.dark_sky_humidity
              name: Outside Humidity
              decimals: 0

Then VIOLA! I have this and it works perfectly:

This totally integrates in HA… NOW I have all the functions of my AC

_________________________ EDIT _________________________________

I did find out that it literally renders Mr.Cool remote useless. It doesn’t function anymore… I have to the Sensibo to change settings… I don’t mind at all but just letting people know.

Hi Guys,

Any updates on the Mr. Cool integration?
I guess a lot of people are looking forward to this as their units are really popular lately.

Thanks!

I am implementing MRCOOL/Cielo integration as we speak!

[Gray.Ghost (Brandon)]

I literally just ordered the hardware to do the ESPhome approach. Any idea of an ETA on your integration?

[cowboysdude (John Wade)]

Yes that does work BUT if you really want a great solution this is it:

Sensibo: Smart Air Conditioner | Control Your AC With Your Phone

This gives you all the controls of the AC… I used the Cielo but didn’t have all the functions this one does

[skillet]

Thanks for the information. Just order two for my mini splits. Got a good Cyber Monday deal ($158 for 2) on Sensibo website. Can’t wait to try them out.

[cowboysdude (John Wade)]

Great deal!!! I know you’ll love the integration much better!
