Multiple Currency Support for Mint.com

As I am integrating more and more services I use on the daily basis with Home Assistant, I was a little disappointed that there is no existing integration for my favorite personal finance application. Upon some research, I found out this was something considered for Home Assistant core components but later removed because it had some issues and was not being maintained. So I thought it was a perfect excuse to get my hands dirty. I had some base code from the original component, so I started fixing the issues to get it in a working condition. However, I realized this will probably never make it to the official Home Assistant core components because the mint client dependency currently doesn’t work headless and the Home Assistant core component require the integrations to work in headless mode. So I decided to publish and maintain it as a custom component on my Github profile.

Multiple Currency Support

In addition to scraping the accounts in various categories, I had a couple extra requirements because I wanted to track my finances in 3 different currencies as I held accounts in 3 different countries. While mint.com allows adding accounts from all three countries, it assumes all the accounts are in USD. I wanted to have a view of all of my accounts after converting the account balances from non-USD currency to USD with current exchange rates. I used a Python package called CurrencyConverter to convert all non-USD balances to USD.
