Hi! This is my first aportation to the community.
I bought a Haier Air Conditioner with wifi support by a usb module, but, instead of buy a wifi module, I made one with a wemos d1 mini and ESP Home, so, I get Home Assistant integration.
You can get the c++ code, .yalm file and “the circuit” in my GitHub
Excellent work. There is a similar project for Mitsubishi heat pumps. https://github.com/SwiCago/HeatPump
In your readme, "wodule"should be “module” - a simple typo I expect.
Nice! Could you please explain a bit more of the process?
Thanks
Hi @diego06
You need a Wemos D1 Mini o other esp module.
You need cut a USB cable and connect it
Finnally, you use the code of my github and flash it with ESPHome, and connected the usb in the usb module connection of Haier internal console.
Hi, very nice work! 
I have one of the 2 haier airco’s connected and is working fine.
Is there a way that you can add a sensor so that i can add only the current temperature to a graph? I’m not that good in programming.
You can use a template sensor to get only the temperature from climate.
- platform: template
sensors:
estudio_temperatura:
friendly_name: "Temperatura estudio"
value_template: "{{ state_attr('climate.haier_estudio', 'current_temperature') }}"
device_class: temperature
Thanks! It is working. I had to add unitit_of_measurement variable to get the historical graph showing it the right way.
- platform: template
sensors:
haier1_current_temp:
friendly_name: "Current Room Temperature Bedroom 1"
unit_of_measurement: '°C'
value_template: "{{ state_attr('climate.haier1', 'current_temperature') }}"
haier2_current_temp:
friendly_name: "Current Room Temperature Bedroom 2"
unit_of_measurement: '°C'
value_template: "{{ state_attr('climate.haier2', 'current_temperature') }}"
I’m glad to hear that.
Enjoy your haier 
thanks a lot… I am still waiting for the installation of the aircon but I will try as soon as I have the system ready!
Using your system it will not work anymore with the app, correct?
Not, the app will not works. Only Home Assistant.
Awesome, but fan speed would be nice, dont want to blow cold air in my cat’s face when we’re away 
Yes, I know it. I am waiting for ESPHome support for Fan Speed
hi, i have problem compiling the code.
i get this

Could you tell me why?
Thank you

Jums… It look like that you include two times the file.
Can you paste the yalm file?
esphome:
name: haier
platform: ESP8266
board: d1_mini
includes:
- Haier.h
logger:
level: DEBUG
baud_rate: 0 #Important. You can't use serial port
wifi:
ssid: "PAOLO_AZZU_CASA"
password: "abcdefghi"
# Enable Home Assistant API
api:
password: "abcdefghi"
ota:
password: "abcdefghi"
climate:
- platform: custom
lambda: |-
auto haier = new Haier();
App.register_component(haier);
return {haier};
climates:
- name: "Haier"
i run the command
esphome esphaier.yaml run
from the directory
C:\esphaier-master\
Good news! I’ve re-installed esphome, now it works fine!
Thank you
Hello guys I did correctly connected my AC with Hassio and all are working excellent except that I can never know when my AC is ON or OFF. Its always shows the mode of the AC before becomes off. It shows that is OFF rarely and randomly. Please is very important for me to know when is ON or OFF when I am away.
I have attached some screenshots that may help.
I don’t understand.
Do you can show the status in Home Assistant?
In your screenshot show “mode: HEAT”, so, it is on. If the current is 19 and the tarjet is 30 and the mode is heat, the AC must heat the room…
No the AC actually is OFF but the mode in logs of ESPHOME shows that is ON and HEAT.
Due to this I can never be sure when the AC is ON or OFF.
