Yes, basically the title. It doesn’t matter what the action is; it simply does not activate when the button is pressed. When I test the action in Homekit, it works fine, so the problem is not about the actions.
Strangely, it only worked once, right after setup. Later the problem arose. Since then, it worked randomly once … And then it stopped working again.
I use my iPad as a hub and restart it. I also disabled actions in the Hue app.
Does anyone have any ideas?
