I am trying to create a heart beat variable that will indicate if a device has not been updating to Ubidots in 1 minute. The update is 1 minute interval.
I created a variable called “Alive Ping” and my device will send a value of 1 every minute.
Then I set an event to change the variable to 0 if the variable is inactive for 1 minute.
However, there is no trigger. Please advise.
