Tion Breazer 3S Go API and Clients

There are thee backend available:

• https://github.com/m-pavel/go-gattlib
• https://github.com/paypal/gatt
• https://github.com/muka/go-bluetooth <- Preferable

  Pairing

  Device must be paired. E.g. using bluetoothctrl

  Reading state

  t = tionm.New("MAC")
  ts.t.Connect(timeout)
  defer ts.t.Disconnect()
  s, err := ts.t.ReadState(timeout)
  fmt.Println(s)

  Tion Breazer Home Assistant MQTT integration

  Sensors

  
  - platform: mqtt
  name: "Temperature Inside (Tion)"
  state_topic: "nn/tion"
  value_template: "{{ value_json.temp_out }}"
  availability_topic: "nn/tion-aval"
  icon: "mdi:thermometer"
  unit_of_measurement: '°C'

• platform: mqtt name: "Temperature Outside (Tion)" state_topic: "nn/tion" value_template: "{{ value_json.temp_in }}" availability_topic: "nn/tion-aval" icon: "mdi:thermometer" unit_of_measurement: '°C'

• platform: mqtt name: "Temperature Target (Tion)" state_topic: "nn/tion" value_template: "{{ value_json.temp_target }}" availability_topic: "nn/tion-aval" icon: "mdi:thermometer" unit_of_measurement: '°C'

• platform: mqtt name: "Speed (Tion)" state_topic: "nn/tion" value_template: "{{ value_json.speed }}" availability_topic: "nn/tion-aval" icon: "mdi:fan"

## Control channel
Turn on/off

{
  "payload_template": "{% if is_state('binary_sensor.tion' , 'off') %} \n  { \"on\": true }\n{% else %}\n  { \"on\": false }\n{% endif %}\n",
  "qos": 1,
  "topic": "nn/tion-control"
}

## Building

make GOARCH=<target arch> IMPL=<backend implementation>

GOARCH - https://golang.org/doc/install/source#environment

IMPL - one of below
  - muka https://github.com/muka/go-bluetooth backend implementation, default
  - ppal
  - gatt 
  - fake 
  - mqtt 
## Magic
 When getting 'Unexpected response length' with muka driver, run once with ppal driver
 In fact it performs adaptor reset like below

sudo hciconfig hci0 up sudo hciconfig hci0 reset sudo hciconfig hci0 down sudo hciconfig hci0 up
