Publishing Zero-Value IOTA Transactions From Node-RED

IOTA’s Tangle lets you publish a zero-value transaction just to carry a message — no coins moved, just data attached and confirmed. node-red-contrib-iota-tx0 wraps that in a single Node-RED node: wire a data source (a sensor reading, say) into tx0 publish, and it uploads the payload to the Tangle and only pulls in the next input once the transaction actually confirms.

Fits naturally into a Node-RED flow reading off a device like a SensorTag — log a value, and get it committed to the Tangle rather than just a database, no server of your own required.
