Wyze sense Mqtt wrapper

A wrapper for the excellent Kevin Vincent (https://github.com/kevinvincent/ha-wyzesense) wyze sense library.Kevins library needs the wyze sense hub to be plugged into a USB port where Home Assistant is running. All my USB ports were taken so I wrote this little wrapper that allows me to run the wyze hub on another machine and communicate with Home Assistant via MQTT.

Setup

I have included a simple unit file so that the wrapper can be setup to run as a systemd service. Edit the files as required.

  • sudo cp wyze-mqtt.service /etc/systemd/system/
  • Edit the service file to suit your requirements
  • sudo systemctl daemon-reload
  • sudo systemctl start wyze-mqtt
  • sudo systemctl status wyze-mqtt

Config file

The wrapper relies on a config file to be present in the same directory. The config file has to be called config.json. A sample is included below:

{
    "mqtt":{
        "host": "Mqtt host",
        "port": "Mqtt port",
        "user": "Mqtt username",
        "password": "Mqtt password",
        "client": "Mqtt client name"
    },
    "publishTopic":"/wyze/",
    "publishScanResult":"home/wyze/newdevice",
    "subscribeScanTopic":"/wyze/scan",
    "subscribeRemoveTopic": "/wyze/remove",
    "usb":"/dev/hidraw0"
}

Home Assistant

To add sensors to the wyze hub, you need to publish a message from Home Assistant that will trigger the scan on the wyze-mqtt wrapper. This is done by publishing to topic defined under subscribeScanTopic. If successful the wrapper will respond with the newly added sensors MAC address. Add the following automation in home assisant to receive the newly added MAC addresses

- alias: Listen for new wyze sense sensors added to hub.
  initial_state: true
  trigger:
    - platform: mqtt
      topic: 'home/wyze/newdevice'
  action:
    - service: persistent_notification.create
      data_template:
        title: Wyze Sense Sensors Discovery
        message: "{{ trigger.payload}}"

Some sample configurations in Home Assistant. One is for a door / window sensor and the other is for a motion sensor.

binary_sensor:
  - platform: mqtt
    name: A Window
    state_topic: "home/wyze/123456789"
    device_class: "window"
    value_template: "{{ value_json.state }}" 
    payload_on: 1
    payload_off: 0

sensor:
  - platform: mqtt
    name: A Motion
    state_topic: "home/wyze/987654321"
    value_template: "{{ value_json.state }}"  
    force_update: true

Todo

  • Add support for removing sensors.
  • Proper logging
  • Mqtt sometimes gets a connection timeout and does not reconnect.

Tested

Tested on Windows 10 running Ubuntu in a virtual machine.
