ruuvi-HASS.io

RuuviTag sensor for hass.io

⚠️ This project is for HASS.io. For home assistant running on virtualenv see the instructions bellow.

This project leverages python3 native bluetooth sockets. For python to have access to the Bluetooth socket family it needs to have been compiled with either lib-bluetooth.h or bluez.h in your operating system.

Recent operating systems like Ubuntu and Raspian should support this when using python3. HASS.io also works after this pull request as well as the official python library after this pull request

Initial setup

Run bleson-setcap.sh if you have installed homeassistant to debian/similar according to default instructions. Requires sudo access!

Instructions

Copy the contents of custom_components in this repo to <config folder>/custom_components (e.g. /home/homeassistant/.homeassistant/custom_components/).

The configuration.yaml has to be edited like this

sensor:
  - platform: ruuvi
    sensors:
        - mac: 'MA:CA:DD:RE:SS:00'
          name: 'livingroom'
        
        - mac: 'MA:CA:DD:RE:SS:01'
          name: 'bathroom'

⚠️ Important note: Do not add more than one ruuvi platform per adapter in the sensors configuration. The code in setup_platform is called once per platform, so at boot time multiple blocking requests to IO will be performed, resulting in only one of the platforms beings successfully setup.

Different bluetooth devices

The hass component supports passing the bluetoth adapter.

  - platform: ruuvi
    sensors:
        - mac: 'MA:CA:DD:RE:SS:00'
          name: 'livingroom'
    adapter: "hci0"

Adapter defaults to the default of ble library

Prerequisites with homeassistant (venv)

(https://www.home-assistant.io/docs/installation/virtualenv/)

1. Install bleson https://github.com/TheCellule/python-bleson

2. Give python superuser permissions so btle scans become possible

#Make sure you have setcap
sudo apt install libcap2-bin

#Activate virtual environment, make sure to use proper path according to your installation
~$> source /xx/bin/activate

#Use the python version you've built your venv with! These apply to python3 & default homeassistant venv installation paths etc
~$> which pythonX 
/srv/homeassistant/bin/python3

#Find actual executable
~$> readlink -f /srv/homeassistant/bin/python3
/usr/bin/python3.8 

#Give permissions
~$> sudo setcap cap_net_raw,cap_net_admin+eip /usr/bin/python3.8

Tested with

• rasperry pi 4 running Hassio (4 ruuvi sensors)
• raspberry pi 3b+ with homeassistant venv installation and 6 sensors
• Intel NUC with homeassistant venv installation and 6 sensors
• (add please reach out so I'll your setup here)

Contributors

This work is a mesh of multiple projects that have been refactored for use in HASS.

• Adding native python bluetooth sockets in HASS base python image - home-assistant/docker-base#53
• Refactoring and reuse of some code from https://github.com/ttu/ruuvitag-sensor to create https://github.com/sergioisidoro/simple-ruuvitag
• Refactoring the work from https://github.com/JonasR-/ruuvi_hass to support bluezson

Special thanks to

• Tomi Tuhkanen for all the work in ruuvitag-sensor lib
• peltsippi for testing
• JonasR- for his code fro
