Inputs not updating on local EmonCMS

Hi
I have en emonpi monitoring my PV , an emontX with HuzzahWifi Monitoring Kitchen Loads and a loca emoncms server.
I have setup the emonpi and emontx to post to the local server and indeed the feeds are showing up and updating.
I tried then to create inputs derived from the feeds but they get created but not updated. (red n/a in the value).
I verified properties of /var/www/html/php-- files on the server and they seem ok.
What could it be?
Since it happens for both i suppose it is a server problem.

this is confusing, “inputs” are created automatically in emoncms and then you create “feeds” from those “inputs”.

feeds cannot update without the inputs updating. looking at the list you’ve posted I see no processlists to link the inputs and feeds.

late night post…
invert inputs and feeds.

Ok that makes a little more sense but I still do not see any processlists, here’s your input table data from above formatted into a table for easier viewing

As you can see there are no processlists so how and where did you create the feeds?

The way emoncms works in when the input is updated it triggers that inputs processlist to be run, on that processlist there should be processes that save the data to feeds. If a feed isn’t updated via a processlist it will never have any data.

If you have created “virtual feeds” on the feeds page they must source data from an actual feed as they do not save data, they populate on the fly when a graph or visualisation or api call is used and hold data in memory eg when a page is opened or refreshed, if no one is asking for the data they don’t actually exist.

My bad… really .
too long I have left the emonpi there.
I forgot the way.
