Extra

Auto supports most of brands set 1 solution

Otherwise, you should use an Android simulator (like BlueStacks) and Wireshark to collect and analyze your AC partner command codes by miio --token yourACPartnerToken --json-dump packetFile, then modify template.json in plugin directory

{
  "010500378033333102": {
    "tpl": "0180333331${p}${m}${w}${s}${th}${l}2",
    "brand": "haier",
    "set": "1"
  }
}

The key is your current AC partner solution model, you can get it by miio --control yourACPartnerIP --method get_model_and_state

"tpl" is this model's command template, you can use ES6 Template Literals with these params:

/**
 * generate command
 *
 * if your ac partner sends commands like 01xxxxxxxxpmwstlx (most of brands set 1 do)
 * then you don't need template config
 *
 * template uses ES6 Template Literals to generate commands
 * supports +, -, *, /, %, ?:, [], toString(16) and so on
 *
 * @param p  number power       0 : off, 1 : on
 * @param m  number mode        0 : heat, 1 : cool, 2 : auto
