Flow Sensor | Interrupt code not running

I found this on a post of Gunners Examples

Another glitch in SimpleTimer (of which BlynkTimer is based) is that when using timer ID labels, needed to do things like disable, enable, delete, etc. timers, it seems like the first timer in your code will also get ‘deleted’… I found making a simple “Sacrificial Timer” solves that little issue :slight_smile:

Possible that this is part of the problem ? My first timer is the one that dumps the flow data… seems likely!

thoughts?
