Usage
-----
### Emoncms post.
The `msg.payload` can contain either a comma separated list of name
value pairs, e.g.
name:value,...
or a comma separated list of values, e.g.
1,2,..
or a simple javascript object e.g.
msg.payload = {temp:12, humidity:56};
If *Nodegroup* is left blank `msg.nodegroup` will used (if set).
This should be a numeric value.
Insertion time can be manipulated by setting `msg.time`. This **must** be in
epoch format - i.e. seconds since 1970.
### Emoncms In:
Fetches last emoncms feed value, returns a numerical value.
