Help needed to get Nodes page working.

I'm not sure if I am understanding how to use the Nodes page in Emoncms.

I can get the 'inputs' to show up on the page by using the node api helper but the 'inputs' don't refresh and any feeds created from this page do not update.

I'm using emontxv3 with emonTxV3_continuous_kwhtotals_eeprom.ino and corresponding decoder on the Nodes page of emoncms Git v8.1.1. Hardware is rpi b  with rfm12pi mk2.

The inputs page and feeds created from it work ok but I need to use the Nodes page to be able to alter datatype for WH recording.

On initial setup the db updater added the nodes table and another table the name of which I've forgotten.

What does the updated since value do? does it just work the first time you send a node packet to the api and then not update there after? with the time since last update ever increasing?

Yes it just works when I manually send a node packet to the api and then the time since last update is ever increasing, eventually changing to inactive.

Are you using the modified oem_gateway as described here: http://openenergymonitor.org/emon/node/4283 to read the serial data from the rfm12pi and post it to the node api?

It sounds like the data isnt getting through to the node api in the first place?

No I'm not using the oem_gateway. I followed this guide  http://emoncms.org/site/docs/raspberrypibuild and installed via Git with PHP gateway. The Nodes page came as a core Module although I had to install the raspberrypi module separately. Thanks for the link, I hadn't seen that page before. Do I need to use the oem_gateway to get it working?

Getting all the parts together to use the new node interface is work in progress, as is the guide, hence why it hasn't been well linked through to the main get started guide yet. The oem_gateway temporary fork that I've linked in the guide is the best way at the moment to post data to the node interface and we're thinking of moving over to using the oem_gateway more as part of the standard build.

The guide is more focused on forwarding the data to emoncms.org, Il add some notes on using it with a local install.

Thanks, Trystan.  I'll give the oem_gateway a try later today.
