My issue is about the Android application. The device is a raspberry pi 3 model B (not +) through MQTT.
It happened to me yesterday that I would click on the digital app button, the state of the virtual button would change (color change) but the action would not propagate to the raspberry pi (no message received).
I had to close the app and restart it for the virtual button to start working again.
To me it seems that the app was silently ignoring a communication error with the server. I would prefer the app to fail in error cases because I have no other way of telling if the action went through if I’m not in my home.
What would be the next step to help diagnose this?
