[SOLVED] Blynk send commands error

Sounds like you are using direct pin manipulation… that will work but I have found it only functional for simple tasks.

Check out the 2nd half of this post about that…

[SOLVED] APP - Label (display widget) sensor stop reading when assign a pin to a switch

OK, I think I understand a bit better… part of the confusion is that the term “label” refers to the labeled portion of the widget, not the actual display portion itself… and both can be adjusted by inputs from code and app. [image] You are using direct pin manipulation of the app, so when widgets are assigned to specific pins, as I understand it, the Blynk library takes over with necessary functions like pinmode (input/output, etc.) assignments. When using analog pins, there can be some case…

Using virtual pins will greatly increase the functionality and reliability of sensors and controls.
