node-red-contrib-semaphore

A Node-RED node that provides semaphore functionality to limit concurrent access to resources. Version 1.0.1 is the current stable release. The package is simple and focused, offering two nodes: 'semaphore take' and 'semaphore leave'. It queues messages on a semaphore with configurable capacity. No frequent updates; maintained for basic needs. Differentiator: native Node-RED integration for flow control and resource limiting.
