Hi all, just sharing this subflow I put together that allows you to switch based on a standard MQTT topic wildcards

[https://flows.nodered.org/flow/e38554543a8cdec6c44eacfc68a0c149](https://flows.nodered.org/flow/e38554543a8cdec6c44eacfc68a0c149)

If follows on from this subject [switch node - mqtt like wildcards for switching](https://discourse.nodered.org/t/switch-node-mqtt-like-wildcards-for-switching/46337)
