@korve/node-red-convert-unit 0.0.2

Converts the message payloads from one unit to another.

npm install @korve/node-red-convert-unit

Converts the message payloads from one unit to another.

Convert code

The node will take in the msg.payload, convert it to the target unit and output the converted payload.

msg.payload is used for the conversation from one unit to another. If the payload is not a number, the node will fail. If a unit is unknown or a conversation from one unit to another is not possible, an error will be reported.
