HomeAssistant-GreeClimateComponent

Custom Gree climate component written in Python3 for Home Assistant. Controls AC's supporting the Gree protocol.

Tested on the following hardware:

Innova HVAC
Cooper & Hunter (CH-S12FTXE(WI-FI)-NG)
AC Pioneer Fortis Series with WI-FI module CS532AE
AC Gree GWH12ACC-K6DNA1D
Inventor Life Pro WiFi
Toyotomi Izuru TRN/TRG-828ZR
Sinclair ASH-13BIF2
TOSOT BORA-GWH09AAB
CASCADE BORA-CWH09AAB
EWT S-090 GDI-HRFN1, EWT S-120 GDI-HRFN1 (WI-FI module CS532AEH)

Tested on these Home Assistant versions:

0.96.x+ (for older versions, please see the releases tab)
0.10X+
0.11X+

If you are experiencing issues please be sure to provide details about your device, Home Assistant version and what exactly went wrong.

If your HVAC has already been configured to be controled remotely by an android app, the encryption key might have changed.

Custom Component Installation

!!! PLEASE NOTE !!!: Skip step 1 if you are using HACS.

Copy the custom_components folder to your own hassio /config folder.

In the root of your /config folder, create a file called climate.yaml

- platform: gree
  name: First AC
  host: <ip of your first AC>
  port: 7000
  mac: '<mac address of your first AC. NOTE: Format can be XX:XX:XX:XX:XX:XX or XX-XX-XX-XX-XX-XX depending on your model>'
  target_temp_step: 1
  encryption_key: <OPTIONAL: custom encryption key>
  uid: <some kind of device identifier. NOTE: for some devices this is optional>
  temp_sensor: <entity id of the EXTERNAL temperature sensor. For example: sensor.bedroom_temperature>
  lights: <OPTIONAL: input_boolean to switch AC lights mode on/off. For example: input_boolean.first_ac_lights>
  xfan: <OPTIONAL: input_boolean to switch AC xfan mode on/off. For example: input_boolean.first_ac_xfan>
  health: <OPTIONAL: input_boolean used to switch the Health option on/off of your first AC. For example: input_boolean.first_ac_health>
  sleep: <OPTIONAL: input_boolean to switch AC sleep mode on/off. For example: input_boolean.first_ac_sleep>
  powersave: <OPTIONAL: input_boolean to switch AC powersave mode on/off. For example: input_boolean.first_ac_powersave>
  eightdegheat: <OPTIONAL: input_boolean used to switch 8 degree heating on/off on your first AC>
  air: <OPTIONAL: input_boolean used to switch air/scavenging on/off on your first AC>

- platform: gree
  name: Second AC
  host: <ip of your second AC>
  port: 7000
  mac: '<mac address of your second AC. NOTE: Format can be XX:XX:XX:XX:XX:XX or XX-XX-XX-XX-XX-XX depending on your model>'
  target_temp_step: 1

In your configuration.yaml add the following:
```
climate: !include climate.yaml
```

OPTIONAL: Add info logging to this component (to see if/how it works)

logger:
  default: error
  logs:
    custom_components.gree: debug
    custom_components.gree.climate: debug

OPTIONAL: Provide encryption key if you have it or feel like extracting it.

One way is to pull the sqlite db from android device like described here:

https://stackoverflow.com/questions/9997976/android-pulling-sqlite-database-android-device
```
adb backup -f ~/backup.ab -noapk com.gree.ewpesmart
dd if=data.ab bs=1 skip=24 | python -c "import zlib,sys;sys.stdout.write(zlib.decompress(sys.stdin.read()))" | tar -xvf -
sqlite3 data.ab 'select privateKey from db_device_20170503;' # but table name can differ a little bit.
```
Write it down in climate.yaml encryption_key: <key>.
OPTIONAL: Provide the uid parameter (can be sniffed) NOTE: This is not needed for all devices
OPTIONAL: Provice input_boolean's to set lights, xfan, sleep and powersave mode on/off.

Optional Features

NOTE: Your AC has to support these features for it to be used.

     temp_sensor: This attaches an external temperature sensor to your AC. Gree unfortunately doesnt support a "current temperature" on its own.
     lights: This switches the backlight of the AC Display on or off
     xfan: This dries the AC after being used. This is to avoid nasty smells from usage.
     health: The air goes through a filter to "clean the air".
     sleep: This will enable a comfortable sleep mode. The AC won't make a lot of noise using this.
     powersave: It seems this mode should be an efficient way of approximately reaching the desired temperature (temperatures will vary using this).
     eightdegheat:  This feature maintains the room temperature steadily at 8°C and prevents the room from freezing by activating the heating operation automatically when nobody is at home over a longer period during severe winter
     air: This feature will extract air from the room. This is to remove hot air or nasty smells from the room.
