Hey Pete - I’m working on a similar issue with new Blynk (Only forced because my phone died and I couldn’t recover the app… drat.)
Attached is the working code I had for previous blynk, I’m having trouble finding the porting instructions or - really - making sense of how to do what I was doing before - but now… can you help?
Attached is the code:
