Struggling to make Nodes page work

I still have not managed to get the Nodes page to work on my setup despite fresh installs of both apt and Git emoncms with blank databases and reverting the emontxV3 to factory firmware image.

I get "true" back when I post     http://192.168.1.103/emoncms/node/set.json?nodeid=11&data=20,20,20,20  or http://192.168.1.103/emoncms/node/set.json?nodeid=11&data=1,2,3,4,5,6   the first time(subsequent times give offset errors) but the first three sensors update once and then freeze.  The sketch can send 6 'inputs' and I should be receiving 4 yet only 3 show up. Sketch is emonTxV3_RFM12B_DiscreteSampling.ino with matching selection on Nodes page. Hardware is Rpi  with rfm12pi v2 updated to latest firmware and emontxV3 with first 3 CT's and Voltage transformer plugged in.

The inputs page has all 6 sensors showing with 4 updating so I don't understand where the Nodes page is going wrong.

Has anybody else got this page to work, if so how?
