Home Assistant - WYZE Sense Component

Special thanks to HcLX and his work on WyzeSensePy which is the core of this component. His reverse engineering talents and development of WyzeSensePy made it quite easy to connect with WYZE sense devices.

Are you a visual person? Here's a video walkthrough of the setup and configuration. Check this README for the most up to date information.

Installation (HACS) - Highly Recommended

0. Have HACS installed, this will allow you to easily update
1. Add https://github.com/kevinvincent/ha-wyzesense as a custom repository as Type: Integration
2. Click install under "Wyze Sense Component", restart your instance.
3. Plug in the WYZE Sense hub (the usb device) into an open port on your device.

Installation (Manual)

1. Download this repository as a ZIP (green button, top right) and unzip the archive
2. Copy /custom_components/wyzesense to your <config_dir>/custom_components/ directory
   • You will need to create the custom_components folder if it does not exist
   • On Hassio the final location will be /config/custom_components/wyzesense
   • On Hassbian the final location will be /home/homeassistant/.homeassistant/custom_components/wyzesense
3. Plug in the WYZE Sense hub (the usb device) into an open port on your device.

Configuration

Add the following to your configuration file

binary_sensor:
  - platform: wyzesense
    device: "/dev/hidraw0"

Most likely your device will be mounted to /dev/hidraw0. You can confirm the hidraw name of the device by running dmesg | grep hidraw to find out what hidraw number the bridge grabbed.

binary_sensor:
  - platform: wyzesense
    device: "/dev/hidraw0"
    initial_state:
      77793176: "on"
      77793193: "off"

By default, the component will restore the last state of the entity prior to a restart. If sensors change state during a restart, the change may not be reflected in HA. In order to combat this you can optionally specify an initial_state for sensors (by mac address) that will be set upon a restart. Be sure to put quotes around "on" or "off" so that they are strings not booleans.

Usage

• Restart HA and the sensors you have already bound to the hub (using the wyze app for example) will show up in your entities as off with assumed_state: true and no device_class. These will update and other attributes will be added once the component hears from the sensor for the first time.

• Entities will show up as binary_sensor.wyzesense_<MAC> for example (binary_sensor.wyzesense_777A4656).

  • As like any other entity you can change the entity id and friendly name from the states page, which will stick even after restarts.

• Call the services below to add and remove sensors from your WYZE sense hub.

• Notes on Individual Sensors

  • Motion
    • State on: Motion Detected
    • State off: No Motion Detected
    • Wyze motion sensors will keep reporting the on state for 40 seconds after the last motion is detected. This is non configurable, but in practice it isn't a big deal and usually makes automations simpler.
  • Door
    • State on: Sensor open
    • State off: Sensor closed
    • Wyze door sensors will report off when the magnetized portion is within ~1 inch of the door sensor body.

• Notes on selected Sensor Attributes:

  • rssi: This stands for received signal strength indicator. Higher values (closer to 0) mean a stronger signal.
  • battery_level: The sensor does a basic calculation with the battery voltage. Because of this, battery percentage may be higher than 100% when you first get a sensor. Enjoy the longer battery life :)

Services

For all services a persistent notification will be sent for both successes and failures.

wyzesense.scan

• Call this service and then within 30 seconds, insert a pin into the hole on the side of a sensor and push until the red led flashes three times. The sensor will now be bound and show up in your entities. You will have to call this service once at a time for each sensor you want to add.

wyzesense.remove

• Removes a sensor. Make sure you call this service with the correct MAC address of the sensor (which is the string of numbers and possibly letters that looks like 777A4656). You can find this in the entity's attributes in the developer section.

Troubleshooting

• Permission denied /dev/hidraw0
  • Additional Information
    • If you see this error on a Hassio installation please follow Reporting an Issue below. It is most likely an issue with your specific setup.
    • This is known to occur on Hassbian. This occurs when the group homeassistant is denied from accessing hidraw devices.
  • Solution
    • Create / Modify the file /etc/udev/rules.d/99-com.rules on your machine and insert KERNEL=="hidraw*", SUBSYSTEM=="hidraw", MODE="0664", GROUP="homeassistant"
    • Ensure the user running Home Assistant belongs to the homeassistant group
• TimeoutError: _DoCommand
  • Ensure that you have updated to the latest component code. If you still see this error follow Reporting an Issue below.

Reporting an Issue

1. Setup your logger to print debug messages for this component using:

logger:
  default: info
  logs:
    custom_components.wyzesense: debug
    wyzesense.gateway: debug

2. Restart HA
3. Verify you're still having the issue
4. File an issue in this Github Repository containing your HA log (Developer section > Info > Load Full Home Assistant Log)
   • You can paste your log file at pastebin https://pastebin.com/ and submit a link.
   • Please include details about your setup (Pi, NUC, etc, docker?, HASSOS?)
   • The log file can also be found at /<config_dir>/home-assistant.log
