Usage

Emoncms post:

Preferred Data Type

The API now accepts a validated JSON object for the name value pairs. This is the preferred data type.

Legacy Data Type Support

The original input API for emoncms used a URI in the format post.json?. If the data type of legacy is selected, the msg.payload can contain:

A comma separated list of name value pairs, e.g.

name:value,...

A comma separated list of values (CSV), e.g.

1,2,..

A simple javascript object (note no quotes) e.g.

{temp:12, humidity:56};

Node

If Node is left blank msg.nodegroup will be used (if set). A Node must be set or the flow will fail.

msg.time

Insertion time can be manipulated by setting msg.time. This can be an ISO format date/time or a number of seconds in epoch format - i.e. seconds since 1970. If no time is set time now is set by emoncms.

Status

The flow will indicate if the node has successfully called the API. This is not a guarantee the data has been inserted to emoncms.

Emoncms In:
