ESP Haier: Haier Air Conditioner + ESP Home + Wemos D1 mini

I have the original ESP32-for-Haier module on my AC, I haven’t yet tried connecting any other “homemade” versions. I can connect a logic analyzer and provide logs if it’ll help in finding out how the original module communicates with the AC.

I don’t know what is “original ESP32-for-Haier module”. I only know the kzw-w001 and kzw-w002

This project is for a homemade replacement of kzw-w001 or 2. I don’t know if it works with others.

Hello everyone, I also own a Tundra Plus unit with the ESP32-for-haier module.
Maybe it is not possible to communicate because the tx and the rx are shifted to 5V?
Unfortunately I don’t have an oscilloscope.

Greetings.

Scroll up, there’s a new module they’re shipping with recent AC models. I have a logic analyzer and I’ll try to see what that new module does.

I haven’t had time to do an analysis with the AC connected, but the ESP32-for-Haier itself provides some valuable info. The TXD0 serves as a debug port at 115200, whereas MCU_TX communicates with the AC at 9600.
Here’s a truncated debug port boot log:

Sometime next week I’ll do a dump while connected to the AC. If anyone’s interested in raw dumps (Saleae Logic or Pulseview), just ask.

I may be very wrong here, but doesn’t the usb connect with a simple uart with the aircon? It could work with the midea way
Bad thing is on my parents house the Haier doesn’t have a usb slot, so I’ll have to check the main board for pins to connect

It does, this has been established, what I’m trying to find out is how this new module polls information from the AC and what it receives back. The bits are clearly very similar to the previous models

New ESP32 modules works with albetaCOM v2 version: GitHub - albetaCOM/esp-haier: ESP8266 code to connect to Haier Air Conditioner ((firmware version R_1.

But when using this version there is a problem with the purify option which turns on every time after changing the settings using the diy module. Maybe somoeone can help to identify problem in code of that fork. Purify problem with some details is also reported in github isuues. I can help with debugging, but my programming skills are not good enough to solve this issue

I’ve completed a full dump of a few configuration command sent via the hON app and the ESP32 module. I made a list of all the commands I sent, but my logic analyzer got disconnected a few times so it’s not complete.
The good thing is that the debug port logs absolutely everything, the JSON it receives from the IoT site, the decoded commands, as well as all the bytes sent and received via MCU_TX (tx_serial e+++ data) and RX (rx_serial e++ data). Hopefuly someone will be able to debug it, I don’t have the time to do it in the next couple of weeks, I can maybe do more of these data dumps if needed.
This is just a snippet, full dump is here: ESP32-for-Haier debug dump - Pastebin.com

Mabe is a Mexican division of Haier, and from pictures I saw of the “Mabe” wifi card, I realized they were both using the same KZW-W001. I just used your code and was able to add my Mabe branded mini split to Home Assistant with little issue. The only thing is when I select Cool in the Home Assistant app, the mini split display shows a green snowflake/green star of some sort, and not the blue snowflake for cooling mode. Everything else works perfect.

Maybe enable “eco mode”?

If you set the cool mode from device remote, with show Home Assistant?

I ordered JST XH connectors but the won’t fit.
They are way to big!

So I went through and reflashed the Wemos and saw all the Deprecated comments on the swing and modes, so I went through the forks of your code.

I found someone, Okison, that had revised your code to incorporate swing and the new Home Assistant code.

Revised Haier.h code incorporating Swing by Okison

The previous issue with the green snowflake disappeared with flashing Okison’s version, but now, the Home Assistant climate page for the mini split shows “Off” regardless of mode. Everything works, but the persistent “Off” is confusing.

Because I still doesn’t have the right connector i put the Wemos D1 at the ESP32.
With the Haierv2.h file from albetaCOM GitHub - albetaCOM/esp-haier: ESP8266 code to connect to Haier Air Conditioner ((firmware version I can communicate with the unit.

It can turn it on and off. When I set temperature it goes to “Health” mode (the same as fresh or purified?). When I set another mode it also goes to health mode.
It turns on when I select a mode like “cool or heat” but it goes on “Health”

I don’t have the knowhow from here. But changing the ESP32 for a ESP8266 gives opportunities.

A little late to the party, but did you check, if your unit is a Midea one? There would be a solution ready to use. It looks a lot like the Midea PCBs…

Check here: Support for Midea A/C

Try to delete or comment row 123:

traits.set_supports_action(true);

I’m using the Haierv2.h file from albetaCOM GitHub - albetaCOM/esp-haier:

I’ve modified Haierv2.h in order to eliminate deprecated warnings and I had your same problem.
For me solution has been to delete

traits.set_supports_action(true);

I’ve a workaround for the “Health” problem.
Below is a new version of Haierv2.h file.
Now is Haierv3.h
The Health problem seems to be related to the Purify flag.

If PurifyControl is set to false (row 471 of Haierv3.h ) the Purify status is toggle at every command
(don’t ask why)
So the solution is to send the message two times with an interval of 1 sec.
Look at row 759

  • Result is that the Purify status after the second message is maintained (if was ON remain ON, if was off remain OFF)

  • You can change the Purify using the remote.

  • Not a perfect solution, just a workaround :slight_smile:

I’ve also removed all the ‘deprecated’ messages.

Here is the modified file

/**
* Create by Miguel Ángel López on 20/07/19
* Modified by Alba Prades on 21/07/20
* Modified by Alba Prades on 13/08/20 
* Modified by Alba Prades on 25/08/20: Added fan, dry and swing features
*      Added modes
* Modified by Carlo Pinasco on 25/08/21: Workaround to fix Purify problem and fix deprecated warning messages.
*   
*   If PurifyControl is set to false (row 471) the Purify status is toggle at every command
*   (don't ask why)
*   So the solution is to send the message two times with an interval of 1 sec.
*   Look at row 759
*   Result is that the Purify status after the second message is maintened (if was ON remain ON, if was off remain OFF)
*   You can change the Purify using the remote.

So this one should work for me too?

I can skip this below?

I’ve modified Haierv2.h in order to eliminate deprecated warnings and I had your same problem.
For me solution has been to delete

traits.set_supports_action(true);

Never mind it’s working thanks.

I have connected Wemos using you code. I can set modes, temperature etc, but hassio always shows climate entity as unavailableBez tytułu

I have tried to upgrade esphome on hassio, now i cant add wemos as climate device:
