Integrating SmartServer IoT and GCP Nodes

...

The MQTT DP Filter function node allows you to specify which datapoints are sent to the cloud by setting up a list of datapoint path names and defining a specific datapoint or using wildcards (e.g., "Tstat-01/AV/7/Room Temperature" or "~.PulseGen/*sensor/*/nvolux*"). The DP Throttle function node reduces the sending of duplicate updates to the cloud. 

For large datapoint count integrations, perform the following steps using these function nodes:
