npm install node-red-contrib-iota-mam


Two different function nodes are now available for

MAM publish (=upload data to tangle) and MAM fetch (=download data from tangle)

Drag MAM function node into a flow and wire it accordingly

CONFIG - At first use the Node-red sample file included !!!

Find included in the root directory a flow sample file called flows_Air.json It provides you with an initial config for ROOT (mamFetch) and a devnet IOTA node.

Also you can switch to the newly added node-red dashboard to publish/fetch data and see a live visualization.

If you have any issues regarding this module, please test with this file and give a clear issue description. Thank you!

MAM fetch

Start deploying a single 'mamFetch function node'. Set its root property (root = "your MAM_ROOT")

wire this node's output to -> any output ( e.g. a chart displaying your msg.payload)


This should hold a non-encrypted (public) data packet sequence. (as of 16 april 2019)

MAM publish

Deploy a sensorTag as input data source. (Please report an issue if you encounter problems with other sensors. We are looking to support all general sensors in the near future)

wire its output to -> mamPublish node

and wire this node's output to an -> (optional) output for logging

The MAM publish gets input data from sensorTag, uploads the data packet it receives (can be a mix of temperature, lux etc) and upon MAM confirmation is ready to take new data from your sensorTag device.
