This seems like a common thing to do, but before trying to get into it, I figure I’ll ask:
What I need to do is have a heartbeat message sent every 60 seconds. When the heartbeat message fails to arrive, I want to send an email. Simple - I’ve seen that shown in the on-line docs.
But next, when another heartbeat shows up, I want to send an email that we’re back on-line.
Also, I need to be able to differentiate between heartbeat messages and error messages. When an Error Message comes through, I want it emailed.
Is this possible with just using “routes”? Any examples? What would differentiate a Heartbeat message from an Error Message?
I will be using the Dash with the Arduino IDE to create the “sender”.
