Either clone the development branch git clone https://github.com/mill1000/midea-msmart.git --branch feature/new_protocol
or install via pip in a venv pip install git+https://github.com/mill1000/midea-msmart@feature/new_protocol
Then execute this example:
import asyncio
import logging
from msmart.device import AirConditioner as AC
from msmart.device.AC.command import GetPropertiesCommand, PropertiesResponse, PropertyId
logging.basicConfig(level=logging.DEBUG)
DEVICE_IP = "YOUR_DEVICE_IP"
DEVICE_PORT = 6444
DEVICE_ID = "YOUR_DEVICE_ID"
# For V3 devices
DEVICE_TOKEN = None # "YOUR_DEVICE_TOKEN"
DEVICE_KEY = None # "YOUR_DEVICE_KEY"
async def main():
device = AC(ip=DEVICE_IP, port=6444, device_id=int(DEVICE_ID))
if DEVICE_TOKEN and DEVICE_KEY:
await device.authenticate(DEVICE_TOKEN, DEVICE_KEY)
# Try to get all properties at once
print("Fetching all known properties")
command = GetPropertiesCommand([x for x in PropertyId])
command._protocol_version = 3
for response in await device._send_command_get_responses(command):
print(response)
# Try to get properties one at a time
for prop in PropertyId:
print(f"Fetching individual property {prop.name}")
command = GetPropertiesCommand([prop])
command._protocol_version = 3
for response in await device._send_command_get_responses(command):
print(response)
if __name__ == "__main__":
asyncio.run(main())EDIT: Updated example

Some functions requested by users (https://github.com/mill1000/midea-ac-py/issues/60, possibly https://github.com/mill1000/midea-ac-py/issues/31) are accessed via the "new protocol".
The protocol has a comment calling it the "variable length attribute protocol". It appears to be a list of properties each with an ID and a value, similar to the capabilities response.
The protocol seems to use either:
For these types, data[1] contains the number of properties.
Each property has:
There seems to be a special message with Response ID of 0xB5 with a Frame Type of 0x5. This message has a single "property" with ID [0x7E, 0x00] and a length of approx 42 bytes. The payload of this "property" seems to be a similar to a StateResponse possibly indicating that when using the "new protocol" the old protocol is repackaged in this message.
