Hi,
It looks like Fitbit has a good documentent API: https://dev.fitbit.com/build/reference/
I think it would be cool to have a Fitbit app for Homey.
Examples what this app could be used for:
- Change lamp colour depending on heart BPM
- Sync alarms/reminders on Fitbit and Homey
- Start coffee machine when you had a bad sleep score
etc…
