What is Node 28?

Emoncms
1

On my Inputs page http://emonpi/emoncms/input/view there is a list of nodes. The first one is ‘Node 28’. What is that?

Also, the second and third are ‘Node emonpi’ and ‘Node emonth’. I understand what those mean but since I have neither an emonPi nor an emonTH they’re just a distracting waste of space. How do I get rid of those three lines?

If memory serves, you have an emonBase?

They could be from a neighbouring OEM system (not likely), the likeliest explanation, after you accidentally used that NodeID when working on something else, is that they are interference that by coincidence happens to have exactly fitted the specification in your emonhub.conf

You can delete all the node specifications in emonhub.conf that you don’t and won’t use, then they should never appear on the inputs page. But even when they do appear there, they don’t cost storage space until you write to a feed. So a distraction yes, but not a waste of storage space.

Thanks Robert. Yes, I have an emonBase.

I haven’t done anything except plug in my two emonTx and create an enphase device that receives updates from a little program that screenscrapes my Enphase Envoy PV-monitoring device and posts the data to emoncms.

Node 28, emonpi and emonth5 all show a status of ‘n/a’. They all have a bunch of input names with no description or process list and an updated status of n/a. So they look completely unused.

Node 28 does not appear in the config file, so that isn’t the problem or the solution. emonpi and emonth5 do, but so do lots of other things that don’t show up on my inputs page, so I don’t think deleting those is terribly sensible either.

Incidentally, when I look at the config view http://emonpi/emoncms/config/view the default is to View log and Auto update log view is ON, but the log display ends part way through a message on 2018-12-08. And indeed /var/log/emonhub/emonhub.log (note extra directory not documented) has exactly the same ending:

2018-12-08 18:20:50,610 DEBUG    MQTT       Publishing: emon/emontx4/temp4 300
2018-12-08
(END)

(the END is from less.)

Odd ending in the log is because:

pi@emonpi:/var/www/emoncms $ df -h
Filesystem      Size  Used Avail Use% Mounted on
...
tmpfs            50M   50M     0 100% /var/log
...

I presume the log isn’t supposed to fill up like that?

You need an emoncms expert, which I’m not. Sorry I can’t help further.

You do occasionally get random nodes appear in the inputs. Just delete it.

7

How? I can’t see any way.

PS I started a new thread for my logging issue.

8

Expand the node, there is a check box next to each input. Select the check box and a delete icon appears at the top. Delete each input deletes the whole node.

If you have a lot there is an API call which I cannot remember off hand.

Never discovered why these odd nodes appear.

[edit] Realised that the new UI has changed. To delete the node (now called a device) click on the cog to the right.

There’s no cog. Did you mean to the right of the node or the right of the inputs? To the right of the inputs there’s a pencil, a dustbin and a spanner?

Deleting all the inputs to delete the node seems a bit weird.

But deleting all the inputs does seem to work :grin:

OK, I am not sure which UI is used by default on the SD card image, sorry.
