@eugene I am not sure I understand your question.
However, in the case of the Wemos board, I opened the app and pressed the button widget assigned to V1 and nothing happened. I also have a Notification widget, two LED widgets and a timer widget. When the app failed to open the door, I pressed the wall button and the door opened and the LED widgets updated (one shows open, the other closed and they read the state of a magnetic switch). So, I disconnected the hardware from the door opener, brought it inside and re-loaded the software. I then re-installed the hardware and tried to open the door without success. At that point, I remembered the issue I had with my other project, so I changed the code from V1 to V10 and also changed the assignment in the app. I loaded the updated sketch and the app was able to control the door again. I then went back and changed the code to V1 and the pin assignment on the app and then it worked with V1 again.
With the Electron project I was doing some testing so I was changing code around, loading it and testing it. I had some issues and left it sit overnight. The next morning when I woke up there was an update so I allowed the update. Then when I started up my electron to re-test the last code, I noticed V0 and V3 button widgets were not doing anything. So, I did the same thing, I reassigned both new pins, V10 and V11. I reloaded the exact same sketch with only those changes and everything worked. Then I changed them back to V0 and V3 and they still worked.
I have only had to do this once on both devices. Once I switched them and then switched them back, they are continuing to work at this point.
As far as I can tell, yes. The wemos is only using 1 button widget, 2 LED widgets, a timer widget and notification widget. As stated earlier, the LED widgets were updating when the state of the mag switch changed. The timer was active so the widget was flashing.
The Electron project uses 6 button widgets, a notification widget and two value widgets. So, not much to tell you here except that V0 and V3 when pressed did nothing until I performed the changes outlined above.
The projects do exist under my credentials on an Android device, Galaxy. I do not have the phone in front of me so I would have to get the specifics to you later.However, the Wemos project has only been operated very rarely and the Electron project has never been operated from the Android. I did do a Blynk update on that device around the same time too so I could check out the new GPS widget.
Let me know if you need anything else.
