I’m just adding heating controls to HADashboard and have a slight problem.
The widget seems to work in as much as the + and - update the target temperature when I check in the Netatmo app, and I hear the boiler fire. But the target temperature displayed on the widget doesn’t change.
For example improved responsiveness you gotta set up the Netatmo integration with a dev account and expose it properly via 443 in order to get webhook events working.
