One-time event detector
I would like to set up an event detector (high limit) but I only want it to run once.
Is there an elegant way to do that?
An example of why I want to do this: We have installed a generator for a customer and wish to be alerted when the customer fires it up for the first time, but not subsequently.
One way to do this would be to use a scripting data source to set a point to the value of 1 when it runs off. Have a state detector on this point for the state of 1. Once the value is set to 1 if there isn't anything to set it back to 0 then the event will never fire again.
You could do the same thing with a Meta data point which might be a bit cleaner.
OK thanks, that seems straightforward enough.
For the record:
I've created a high level detector on a kW measurement point that should fire when the customer connects for the first time. I also created an empty binary meta-point called 'one-time detector'.
I set up my event detector to set this meta-point to 1 when the high kW condition triggers.
On my 'one-time detector' point, I set an event handler to send an email when the point value is 1.
