I installed the latest emoncms to my raspberry pi yesterday.  I like the changes/improvements.

However, my NanodeRf could no longer post data to my local emoncms.  It was working fine for about 3 months with the previous emoncms.

I don't understand what is going on behind the scenes on emoncms, but I fixed it by changing my NanodeRf code.  I am using a modified version of NanodeRF_multinode.ino.

To fix the problem I changed one line in NanodeRF_multinode.ino, using "api" rather than "input":
change
        str.print(basedir); str.print("/api/post.json?");
to
        str.print(basedir); str.print("/input/post.json?");

Like I said, I don't understand this.  Interestingly, either "api" or "input" work when posting to emoncms.org rather than my local emoncms.  From my web browser I can send:

http://raspberrypi/emoncms/input/post.json?csv=100,200,300     ====>  this works
http://raspberrypi/emoncms/api/post.json?csv=100,200,300     ====>  this FAILS

http://emoncms.org/input/post.json?&csv=100,200,300     ====>  this works
http://emoncms.org/api/post.json?&csv=100,200,300     ====>  this works

On Github, I see that the NanodeRF_multinode_static_IP.ino created three months ago also changed "api" to "input", but none of the other NanodeRf versions have that change.
