Go implementation for MiIO protocol. inpsired by miio.dart
go get github.com/icepie/miio.gofor get device token and device id, you can try micloud
device := miio.New("192.168.1.12").
SetToken("ffffffffffffffffffffffffffffffff").
SetDid("did") // some device must use the true device id
// get device info
info, err := device.Info()
if err != nil {
panic(err)
}
fmt.Printf("%s\n", info)
// for get siid and piid, see https://home.miot-spec.com/
// get properties
getProps, err := device.GetProps(miio.PropParam{
Siid: 5,
Piid: 1,
}, miio.PropParam{
Siid: 5,
Piid: 2,
})
if err != nil {
panic(err)
}
fmt.Printf("%s\n", getProps)
// set properties
setPropsParams := []miio.PropParam{
{
Siid: 5,
Piid: 1,
Value: true,
},
{
Siid: 5,
Piid: 2,
Value: 0,
},
}
setProps, err := device.SetProps(setPropsParams...)
if err != nil {
panic(err)
}
// Do action
action, err := device.DoAction(miio.ActionParam{
Siid: 2,
Aiid: 1,
// In: []any{0, "test"}, if need to send extra data
})
if err != nil {
panic(err)
}
fmt.Printf("%s\n", action)
// some old devices can not use the standard way to control...
// https://github.com/icepie/miio.go/issues/1
// you can try to send raw data, like:
getProps, err := device.Send("get_prop", []interface{}{"power", "mode", "fan_level", "ver_swing"})
setProps, err := device.Send("set_mode", []interface{}{"cool"})
// or you can try: https://github.com/icepie/micloud0 1 2 3

Packet Length: 16 bits unsigned int
Length in bytes of the whole packet, including header(0x20 bytes).
Unknown: 32 bits
This value is always 0.
0xFFFFFFFF in "Hello" packet.
Device ID: 32 bits
Unique number. Possibly derived from the MAC address.
0xFFFFFFFF in "Hello" packet.
Stamp: 32 bit unsigned int
Continously increasing counter.
Number of seconds since device startup.
MD5 Checksum:
Calculated for the whole packet including the MD5 field itself,
which must be initialized with token.
In "Hello" packet,
this field contains the 128-bit 0xFF.
In the response to the first "Hello" packet,
this field contains the 128-bit device token.
Optional variable-sized payload:
Payload encrypted with AES-128-CBC (PKCS#7 padding).
Key = MD5(Token)
IV = MD5(Key + Token)
