After looking up ESP8266 ITimer I believe I found how to set this up correctly. I spent a good while reading about ISR and Arduino Timers. Going to try it out and will return with an updated sketch once completed.
I found this thread which seems to be exactly what i need to do: Mission-Critical functions where Blynk really serves simply as a GUI.
That is how I have been using blynk for the past years; mostly for charts and data logging and device parameters setup.
With the new Blynk Pro plans I am thinking of manufacturing devices that eventually I can sell to customers something that wasn’t allowed to do before per Blynk’s regulations. So to answer your question:
That’s the plan.
That is exactly what I want to do.
Again thank you.
