Follwing the Idea from Support for Nest Protect - #7 by PaulNL
Small Readme as a Workaround for anyone on Hass OS:
If you’re on Hass OS it’s easy to install the Portainer Addon and simply create a new container with Network Mode ‘host’ using this image: oznu/homebridge
Afterwards the UI is accessible on
yourhomeassistant-ip:8581
login: admin/admin
If you need the Google Refresh Token then clone the repository from GitHub here (on your local machine - not your HassOS host) and then run
npm install
node login.js
And you should have everything running. Don’t forget to restart the Container after adding the Nest Integration in Homebridge - then your Devices should be detected. Afterwards look at your Homeassistant Lovelace-Frontend in the Integrations Section - it should auto-detect it and also add all devices after pairing.
