I’d love to, but unfortunately I don’t think there’s a solid way forward at the moment. I did some research into the Dexcom API and realized it isn’t meant for realtime data. It runs 3 hours behind and is meant more for retrospective analytics.
I also looked into how Home Assistant fetches data and found gagebenne/pydexcom. It uses an unofficial API which is realtime, but unfortunately it authenticates via username and password instead of Oauth2. I’m not comfortable creating an integration that would store user passwords in plain-text, so I think we should hold off from using that API until Tidbyt supports encrypted fields.
