Simple Gate

A Node-RED gate node that controls message flow by opening or closing a gate. Current stable version is 0.5.2, released with support for asynchronous context stores and improved persistence. Key differentiators: allows user-defined control topic and command strings, supports toggle and status commands, and can restore state from persistent context stores if available. Cannot queue messages; for queuing, use the companion node-red-contrib-queue-gate package. Compatible with Node-RED 0.18+.
