Yes, it was changed in my attempts to resolve the issue. Trying to see if alphabetic characters were a problem.
A bit of playing with direct urls reveals some inconsistency.
This
http://192.168.0.3/emoncms/input/post.json?node=IotaWatt&json={1:0}
creates a node called IotaWatt.
This
http://192.168.0.3/emoncms/input/bulk.json?data=[[0,60,1,2,3,4,5,6,7,8,9,10]]
creates a node called 60 with 10 entries.
This
http://192.168.0.3/emoncms/input/bulk.json?data=[[0,IotaWatt,1,2,3,4,5,6,7,8,9,10]]
generates an error message - Error: Format error, json string supplied is not valid
Having created Node 60 I tried changing the IotaWatt setup to use node 60 to see if it would use those, but it’s not looking good.
SD initialized.
