Might be simpler to use a webpage card to show the page you’re thinking of scraping from. I do this to provide a dashboard wiki for my installation - works very well.
But you can’t make automations against that. Last night I prototyped a way to use mintapi on the CLI to pull down a json packet of mint and then parse and send that data via MQTT into HA.
It works … but it’s messy. My personal use case is to alert me when certain accounts get too low and I need to move money around.
As long as it’s in mint which I think it is … it should be there - however - it’s pretty low on my priority list at the moment. I am currently trying to improve the intellifire integration…
Did you get this up and running with balances however?
