Third party integrations

Nope unfortunately no news. Let me know if you find something out

I was able to find out a few things because I have the module myself, but unfortunately, it seems to use a completely different protocol. However, implementing it still seems feasible. For an initial test, the pinout and initialization.

Climate pinout :
GND RX TX VCC NC NC NC NC
Parameter:
9600 Baud 8E1

INIT:

Modul: 02FFFF0000000002
Klima: 02FFFF8000000A0100D00000050130000170
Modul: 02FFFF0101000100FF
Klima: 02FFFF8101000080
Modul: 0305B0001000003B # WIFI LED & Connected
Klima: 06 # ACK

TEST FAN Mode :

Modul: dd0bfb6001113400ff8000e48170
Klima: 06
DC0BFC738034FF0084000000004F
Modul: 06

Test Turn off FAN

Modul: dd0bfb6001213400ff8000e4b130
Klima: 06

Hi! Looks like that dongle USB connector is tied directly to the D+,D- pins of ESP(which is the normal). For the AC control you need that the USB to be connected to UART TX/RX pins of ESP.
You can try with one of the modules already posted or you mod your existing dongle.

Yeah my Bosch Climate 6000i also didnā€™t seem to work with the midi protocol :frowning: I powered it successfully via GND & VCC and then tried all kinds of combinations for the RX & TX pins but never received any data.

Hi there,

does anyone know if the module above is compatible with Iobroker as well? Like this adapter? I am not running HA unfortunately but need a proper integration into my ecosystem.

@h4b3ck I decompiled the HomeCom Easy apk and found some info. I suspect that our models donā€™t use the midea but the sharp protocol.

Itā€™s also displayed on the inner circuit

Whatā€™s the voltage for the data pins of the AC? Arenā€™t they 5V ? Arenā€™t you supposed to use a logic level shifter?

So this thing is anything but Bosch?:))

Iā€™ve ordered five of these, coming tomorrow, so just wanted to clarify the steps I need to takeā€¦

  • Plug into the Air Conditioning unit (3000i)
  • Once plugged in, there should be a hot spot
  • Connect to the hot spot and presumably itā€™ll open up a UI to input my WiFi
  • Add to Home Assistant (should be discovered automatically)

Thatā€™s it, right?

I have a first working version, if you tell me your GitHub username, I can invite you to test it. The version is not yet ready for public release.

oh wow thatā€™s awesome! My github username is nico1510

Hi there,
Iā€™m a newby to ESP32.

It is good if I buy ESP32-S2 (some like this ā€¦ that has USB-C on-board ) and use a usb-C to usb-A converter ?
