Get tokens for Google Home Foyer API

Get tokens for Google Home Foyer API

Intro

This script (python 3) generates tokens that can be used when making requests to the Google Home Foyer API. There are 2 kinds of tokens used here:

  1. Master token - Is in the form aas_et/*** and is long lived. Needs Google username and password.
  2. Access token - Is in the form ya29.*** and lasts for an hour. Needs Master token to generate.

If you do not want to store the Google account password in plaintext, get the master token once, and set it as an override value.

It's safer/easier to generate an app password and use it instead of the actual password. It still has the same access as the regular password, but still better than using the real password while scripting. (https://myaccount.google.com/apppasswords)

Usage

# Install python requirements
pip install gpsoauth

# Update the constants at the beginning of the file

# Get the tokens!
python3 get_tokens.py
# Get tokens for Google Home Foyer API
# https://gist.github.com/rithvikvibhu/952f83ea656c6782fbd0f1645059055d

same story as above, I cannot get the script to work. I also have passkeys enabled, I tried using both my actual password and two different application passwords just in case.

For anyone still facing an issue with this script, see this comment: leikoilja/ha-google-home#599 (comment)

Worked for me, first try.

I got the double whammy here: the app password copy/paste from the Google website does indeed contain hidden characters; after I retyped that I tried several scripts (in homeassistant's terminal) and must be hitting the library issue, so retyped in the dockerised script is the way to go.

The docker command in the main readme is slicker than the one in the comment linked above as it does it all on one line.

So thanks @Telmo and @Brephlas !
