I’m not an HVAC expert, but according to this nicely written manual I found for some multi-split unit, I think these two sensors are:
Outdoor In Air Temperature = Compressor Suction Temperature
Outdoor Out Air Temperature = Compressor Discharge Temperature
79°C on discharge while heating seems right.
Hi @evlo Can you provide logs for every action? Including setting away with the remote. I need 15-20 seconds of logs before action and 15-20 after.
Hi all!
I’m very grateful for all the work you guys have put into this integration as it helped me to get my Haiers into HomeAssistant even though an official integration still lacks within the HomeAssistant ecosystem.
Unfortunately, the whole experience wasn’t without some serious hours of troubleshooting as I didn’t get to a working setup without a fight. So I thought I’d document this for anyone who might experience a similar situation.
Original Setup:
New Setup
Process
At this point I thought I got it all working in one go, but boy was I wrong.
Once I installed the dongle in the Haier unit it powered on and was discovered by ESPHome. However, it showed timeouts in the log and the entities were not showing any data in HomeAssistant. When I clicked a button in the HVAC card in HA, it did show the action in the ESPHome log, but showed an error sending the request to the Haier.
I started to read up on potential issues and tried to strip the configuration to its bare minimum, even re-soldered the wires to make sure everything was correct. I don’t know how many time I re-flashed the configuration to the ESP-12 D1 Mini, but it was a lot!
Long story short…
As my units only worked with the SmartAir2 app, I only focussed on this protocol for the configuration, assuming the Hon protocol would not work.
Turned out I was wrong again, as this caused the issue all along.
Lesson learned:
I hope this helps others who struggle with getting their older Haier units to work. I know it would have saved me at least a few hours of irritation and troubleshooting.

@Trtr1010
From your previous message, I got an impression that you can’t compile your config. But in this one it looks like you successfully compiled FW but it is not working. Can you provide me ESPhome logs from your device? I need 20-30 seconds of logs.
Thank you for the response
In fact, I have reached an advanced stage of preparation and then the matter worked for me, but I have a question
My AC on the smartair2 protocol, can I use the outdoor temperature sensor?
And what are the commands that can be used in this protocol?
Can I change the protocol to hOn?
Thanks
@Trtr1010
Glad it worked for you.
Unfortunately no. External sensor is not supported by SmartAir2 protocol.
Didn’t get your question. What commands do you need?
No. Internal block support only one protocol. If you use wrong protocol, internal block will not understand it.
Hello, have problem with my AC unit, worked great with custom_component from GitHub - MiguelAngelLV/esphaier: ESP8266 code to connect to Haier Air Conditioner with wifi module support
until esphome update, no longer support custom_components, any idea how to make it work again ?
Please use build-in components from esphome Haier Climate — ESPHome
I have succesfully managed to liberate myself from the Haier hOn app, replacing factory installed ESP32-for-Haier WiFi module with a D1 Mini ESP-8266EX board. ESPHome configured the device perfectly for Home Assistant, not in the least thanks to all of the useful instructions and examples on this forum … thank you, thank you, thank you, to all who have contributed!
I have one remaining question… The interface shows next to the target temperature the “Current temperature” (see screenshot). That is the inside temperature which was also visible previously in the hOn app, so my hardware supports it and somehow must be able to measure this temperature. However, I cannot find this as a separate Sensor entity in Home Assistant, it is not a disabled entity, and it does not show in the optional sensors which can be found at Haier Climate Sensors — ESPHome. I really would like to expose this, for example, to assign it as a Temperature sensor in the applicable Area in Home Assistant and run automations with it (“if room temperature drops blow certain value, turn on heat”, etc.). I’m not interested in the Outdoor temperature which can be successfully enabled with the “outdoor_temperature” statement in yaml. Can anyone help with this please?
Much appreciated!
Hi @gNeeUs,
I prefer to follow the standard way that all other climates use. Usual procedure climate component exposes current temperature to parent Climate and it passes it to Home Assistant as attribute (current_temperature). There are many ways to use this value in HA. For example, you can create automation that tracks changes of this attribute, or create template sensor in Home Assistant itself and expose current_temperature attribute of your climate (Template - Home Assistant). Alternatively, you can implement similar thing in ESPHome template sensor (Template Sensor — ESPHome).

Hi @izzatbek2315. So what is wrong? What kind of help do you need with your config?
I appreciate you designing this in a standard way @paveldn, I wouldn’t have it any other way. Thank you for the tip regarding the inside temperature, I did find the attribute! To expose that attribute as a sensor I found a little gem aptly named Attribute as Sensor which can be installed as an Integration. I now have 3 sensors in the house without any additional cost or installation effort.
My goal is to create a thermostat automation to turn the heat/cold on/off based on the reading of the current temperature and this will work much easier now that I can include those sensors in the automation.
Cheers!
Worked perfectly using a Waveshare ESP-32-C3-Zero. The module is small enough to fit perfectly in the AC cavity.
Nothing too complicated to configure:
esp32:
board: esp32-c3-devkitm-1
framework:
type: esp-idf
uart:
baud_rate: 9600
tx_pin: 21

Very impressive work by @paveldn . thanks a lot for all the time you have invested in this project.
I am looking forward to replace the modules in all my AC units. They are much more responsive than the standard hOn cloud based solution.
Hallo ich schreibe in Deutsch da mein Englisch echt nicht gut ist. Ich wollte nur anderen Usern bescheid geben das dieses Skript unter ESPHome mit Anbindung an HomeAssistant auch für Klimaanlagen von Heiko funktioniert im hON Modus. Heiko ist ein polnisches Produkt was von Haier ?! Produziert wird ich habe den Original WLAN Dongle gegen einen ESP8266 ausgetauscht und es funktioniert hervorragend. Heizen, Kühlen, Temperatur, Licht an und ausschalten funktioniert. Und ein paar Sensor Werte kann ich auch auslesen. Meine Klimaanlage ist eine Heiko Brisa 3,5kW. Gruß, Daniel aus Deutschland
Unfortunately no. External sensor is not supported by SmartAir2 protocol.
Is an external sensor supported by the hOn protocol? Also not right?
Hi, after many year for a trouble i open my AC Haier and i found on the board a connector with 5V GND TX RX. My old AC link 2010 yr don’t come with any usb or wifi but on the sticker in the internal unit i see that connector refer to a NET appliance so i think i can try whit a 8266 right??
So i flashed with esphome but i don’t understant the right config to upload…i see github of @paveldn but i’m lose in the many file “sorry” someone can help me?
Thank’s Mauro
