I am using a ESP8266 NodeMCU to control a little home grow box with a dashboard where also 2 buttons are integrated to start/stop and reset the cycle. Everything is working fine with webbrowser of cayenne but not with the iOS App. Some values are updated only once when I open the app and some not at all. Buttons are not working as well with the app. I already tried to delete and reinstall the app but without success.
Any idea what the problem is?
