I’m using gab.lau’s excellent nodes with node red (all latest versions).
I would like it so when the virtual LED on V5 goes on/off on my iOS app, it sends a corresponding payload to a debug node (for now).
This works for virtual Buttons (e.g. Pin V2 Write Event sends 1 or 0 to debug node).
But when I try it with a virtual LED, it does not send anything from either Write or Read Event nodes. I would think when the state of V5 is updated on the Blynk server, it could trigger an event.
Do I need to amend my Arduino device code to send a message to MQTT, or can this be achieved using nodes alone?
Thanks for any advice
