Average 5 Pings

This flow uses the node-red-node-ping and node-red-contrib-particle nodes to ping a host once per second, calculate the average of those 5 pings, then send the output to a spark/particle core.

You could ignore the particle nodes and send the output directly to whatever you like.

You could also switch the node-red-node-ping for the node-red-contrib-advanced-ping node which will allow you to trigger it at will rather than at set intervals

NOTE: This flow requires you to configure the particle cloud with your own API key.
