Node-RED is a visual tool for wiring the Internet of Things, but it can also be used for other types of applications to quickly assemble flows of services. Node-RED is available as open source and has been implemented by the IBM Emerging Technology organization.
Node-RED MySensors protocol decoder / encoder / wrapper package contains a node to decode / encode MySensors serial protocol to / from node-red messages. It also appends MySensors specific data like sensor type, nodeid etc. which can then be sent to MySensors network.
MySensors is supported through the Serial Gateway, Ethernet Gateway.
