Just wanted to report that with the new release of Hubitat 2.1.4 you can pass variables back and forth between RM and webCoRE. Variables are setup in RM by creating a Global Variable and assigning it a connector. This will create a new device on the hub called "Rule Machine Connectors" and in that device there will be a child device containing the name of the Global Variable you created in RM.
This is a great way to be able to run the two rules engines and give them a way to communicate. Plus you can change these variables through the Hubitat dashboard. Very cool!
