How to read blynk button pressed inside the arduino sketch?

Thx and bye, guys! I found what i was looking for: tasmota.

Good luck for you all.

I have a particular doubt about this. If I write a value to a virtual pin V1 from a different device (not a widget button), the code inside the Blynk_WRITE(V1) does not activate. How can I activate a Blynk_WRITE block every time the value in V1 changes?

Can you explain more about exactly what you’re doing that doesn’t work for you?

You talk about writing to V1 from “a different device”, which makes me think that you may have multiple devices sharing the same Auth code. If this is the case then that’s why it isn’t working.
