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
