Hi,
i'm stuck with following problem.
I get incoming messages of a a "tcp in" node from a keyence vision system if this system detects an error.
And i want to send a message via telegram if there are 6 errors in the last 10 minutes.
My idea is to create an array 0-9. Now i count the incoming errors every minute to array[0]. Also i shift the array every minute so array[8] goes to array[9] and array[7] goes to array[8] ... and array[0] is set to 0.
Is this the right direction or is there an easier way?
EDIT: I just found this node which is eventually suitable: [node-red-contrib-msg-speed (node) - Node-RED (nodered.org)](https://flows.nodered.org/node/node-red-contrib-msg-speed)
So i change my question: Is my idea a good way if i want to solve my problem with the function node?

Can that be turned round the other way and instead send the message after 10 minutes if there is not a good signal in that interval? That would be much easier to implement, using just a Trigger node.

Unfortunately not, because sometimes the mashine is turned off or paused.
But i use this method already for a different solution. Basically it works like a watchdog.

Is there no way of knowing that the machine is turned off or paused?
If not then you will have to implement something along the lines you have suggested.
