You should probably use Python or Node.js as your programming language, or use a different client device such as a NodeMCU or ESP32.
I’m not sure if Python or Node.js work with Blynk 2.0 yet, so my preference would be to use a different hard ware device as your client.
Either way, you need to use virtual pins with Blynk 2.0, and have the appropriate virtual pin handlers in your code. This is how they work in C++…
I have used Python for some simple projects in the past, but I was hoping to get around actual programming the Pi by means of the Blynk. app…
The idea of the whole project is to remotely monitor temperatures of my thermal solar panels (an other temperatures of my heating system) plus I like & know the Pi from using craftbeerPi in my brewery…
Would using the legacy Blynk App help in managing the GPIO’s?
What would your suggest be the best way to proceed in this situation?
