The Node-RED for PAC Control nodes use the PAC Control REST API on groov EPIC processors.
Any program using the PAC Control REST API must use a groov user with an API Key, even from Node-RED running on the same groov EPIC processor.
Add a User with REST API Permissions
In groov Manage on the device, go the Accounts page.
Add a user with permission to use the Control Engine REST API. This will allow the user’s API Key to be used from the nodes.
Continue to installing Node-RED.
