Will the linked unit work with my Mr Cool DIY unit? 36k BTU condenser with 12k BTU air handler

Hi Guys,

I have a Midea AC and also use the Midea Aircon plugin.
Everything is working fine, exept the climate thermostat card/entity will not update till I execute a command via the card! This means, if I use the wired airco controller the status in hass is not updated!
Any ideas how to fix this?

regards,

Jurgen

I have a Midea AC, seems like it has V3 protocol and there are no realtime updates through the cloud, so seems like I have to make a local server, but I can’t find any info about it. can you give a link to these instructions?

I’ve got the osk103 dongle, popping it open i wonder if it’s possible to make use of any of the pins on the dongle pcb. or maybe flash it with the fake server? seems like this thing can be reprogrammed no? i’m sure some of you more knowledgeable folks have probably already given it a look, but incase no one has here’s a pic of the pcb.

If not i’ll try the esphome route,
Thanks

I own a Midea AC model MAP12S1BWT, it has wifi integrated into it (no dongle). Does anyone know which library, if any, supports this one?

(Edit: After playing around with it more I decided to just jump in head first and got it working with the Midea Smart Aircon repository. Thanks guys!)

can you send the repository url

aceindy · June 28, 2021, 2:40pm

Mean this one? GitHub - mac-zhou/midea-msmart: This is a library to allow communicating to a Midea AC via the Local area network.
But the ESPHome Dongle is much more stable

Xelinor · June 28, 2021, 3:28pm

Yep, that’s the one I used. I don’t have a dongle on mine unfortunately, and being in the middle of a massive heat wave I’m not really willing to risk disassembling my AC to find it at the moment

For now, this seems to work, even if the device shows unavailable half the time (it did when using the Midea app too, I assume it’s wifi module is just crappy)

No feedback on this one?

aceindy · July 8, 2021, 6:33pm

Not really…
Can you see the led on the esp01 flashing?
Should flash about once every seconds (indicating serial communication)
Oh…wait…this is not about the esp01 dongle, but the midea custom addon…

Not sure if that still works…especially with latest version updates it is problematic.

I have used it for 1 week and was then fed up with it, and I’m happy I got the esp01…

I can you recommend one… if you’re not comfortable making one yourself, you can order a prebuilt one as mentioned in this thread.
Succes ermee

Hi.
Does anyone know if it is possible to use the component (that i would use on d1 mini ) with the Midea Right air conditioner? On the specifications reports the wifi ce-sk103 (and not ce-Osk103)
Thanks very much

mac_zhou · August 10, 2021, 10:02am

The new version already supports 8370.Need to get token and k1.

adb logcat | grep doKeyAgree

Lukacs_Attila · August 10, 2021, 11:16am

Thank you for hard work! Appreciated!

mac_zhou · August 10, 2021, 12:04pm

Don’t worry about the model, just run the following command on a machine on the LAN to know if it is supported.

pip3 install msmart
midea-discover

silmakka · August 11, 2021, 9:00am

Thank you very much @mac_zhou ! New version with V3 work like a charm.

After latest msmart update with my so far perfect OSK-102 I receive (integration unavailable) and:

Can I roll back msmart somehow or what is going on?
