How to use

The API key is 3742e9e5842d4ad59c2db887e12449f9 if you extract it from their .apk package. But I'm not sure.

Installation

gem install midea-air-condition

CLI

Configure

Before you can use the client you have to configure it. It will ask for email, password and app key. The configuration will be saved in ~/.midea/config

midea-ac configure

List devices

You can list all the devices connected to the account

midea-ac list

Get device

You can get the status of a device

midea-ac get DEVICE_ID

Set device

You can Set the power temperature and fan speed of a device

midea-ac set DEVICE_ID --power=[on|off] --target-temperature=TARGET_TEMPERATURE --fan-speed FAN_SPEED

Example:

require_relative 'lib/midea_air_condition'

client = MideaAirCondition::Client.new(
  'username/email',
  'passsssssword',
  app_key: 'api_key'
)

client.debug = true
client.login
devices = client.appliance_list

target = 0

devices.each do |device|
  print "[id=#{device['id']} type=#{device['type']}]"
  print " #{device['name']} is "
  print 'not ' if device['onlineStatus'] != '1'
  print 'online and '
  print 'not ' if device['activeStatus'] != '1'
  puts 'active.'

  target = device['id'] if device['onlineStatus'] == '1'
end

# Status
builder = client.new_packet_builder
command = MideaAirCondition::Command::RequestStatus.new
builder.add_command(command)

response = client.appliance_transparent_send(
  target,
  builder.finalize
)

device = MideaAirCondition::Device.new(response)

puts "#{target} is turned #{(device.power_status ? 'on' : 'off')}."
if device.power_status
  puts 'Details:'
  puts "  Target temperature is #{device.temperature} celsius."
  puts "  // Indoor temperature: #{device.indoor_temperature} celsius."
  puts "  // Outdoor temperature: #{device.outdoor_temperature} celsius."
  puts "  Mode: #{device.mode_human}."
  puts "  Fan speed: #{device.fan_speed}."
  puts "  TimerOn is #{(device.on_timer[:status] ? '' : 'not')} active."
  puts "    at:  #{device.on_timer_human}" if device.on_timer[:status]
  puts "  TimerOff is #{(device.off_timer[:status] ? '' : 'not')} active."
  puts "    at: #{device.off_timer_human}" if device.off_timer[:status]
  puts "  Eco mode is #{(device.eco ? 'on' : 'off')}."
end

# Turn on
builder = client.new_packet_builder
command = MideaAirCondition::Command::Set.new
command.turn_on
command.temperature 25
builder.add_command(command)

response = client.appliance_transparent_send(
  target,
  builder.finalize
)

device = MideaAirCondition::Device.new(response)
puts "  Target temperature is #{device.temperature} celsius."

# Turn off
builder = client.new_packet_builder
command = MideaAirCondition::Command::Set.new
command.turn_off
builder.add_command(command)

response = client.appliance_transparent_send(
  target,
  builder.finalize
)
device = MideaAirCondition::Device.new(response)
puts "  Target temperature is #{device.temperature} celsius."

# Set temperature to 23 celsius
builder = client.new_packet_builder
command = MideaAirCondition::Command::Set.new
command.temperature 23
builder.add_command(command)

response = client.appliance_transparent_send(
  target,
  builder.finalize
)

device = MideaAirCondition::Device.new(response)
puts "  Target temperature is #{device.temperature} celsius."

CRC Table + base64

I tried to generate the crc8 table, but I can't. The table itself is a very long one, so I packed base64 encoded it.

At least this one is not working:

crc8_table = []
256.times do |i|
  crc = i
  8.times do
    crc = (crc << 1) ^ (crc & 0x80 != 0 ? 0x07 : 0)
  end
  crc8_table[i] = crc & 0xff
end

The final table should look like this:

crc8_854_table = [
    0x00, 0x5E, 0xBC, 0xE2, 0x61, 0x3F, 0xDD, 0x83,
    0xC2, 0x9C, 0x7E, 0x20, 0xA3, 0xFD, 0x1F, 0x41,
