Input list doesn't load

Emoncms
5

Hello @margusv, @ivancaregnato.

Could you check the result from this URL which will attempt to access the underlying input list data:

http://emonpi.local/emoncms/input/list.json

If there are no error’s it should show something like this:

[{"id":"1","nodeid":"1","name":"1","description":"","processList":"1:1","time":1494322844,"value":100},
{"id":"2","nodeid":"1","name":"2","description":"","processList":"","time":1494322844,"value":200},
{"id":"3","nodeid":"1","name":"3","description":"","processList":"","time":1494322844,"value":300}]

Hopefully it should give us an error in your case which we can use to debug the issue further.

Hi @TrystanLea , thank you for your reply.
Actually I’m away from home but I can connect to my raspberry directly through a NAT.
The result is a blank page with Chrome (or a blank file if I try to open the page with IE11).

7

same here, with safari and chrome - just blank page *( full white)
when I don’t loaded the name and password from another session, then laoding: " {“success”:false,“message”:“Username or password empty”}", but after start the session from another page then loading just blank page

Just updated to Emoncms 9.8.4 | 2017.05.01, but still same ;(

@margusv are you able to find out which version of the php redis library you are running?

If you run $ pecl info redis

at this top it should say something like:

About pecl.php.net/redis-3.0.0

9

You should perhaps be wary of asking any specific package manager what it thinks is the current version in use just in case multiple methods of install have been used (eg the emonSD). A safer method is via “info.php” (eg http://emonpi/info.php) or as of v9.8.4 of emoncms, the versions of all loaded php modules are displayed on the admin page (if a version number exists that is).7

There’s a discussion here where @JumpMaster appeared to have the same problem. But then it appears to be fixed by version 9.3 which does not seem to be the case in your case…

Did you run the database update?, it should do so as part of EmonPi update.
Otherwise your redis and php versions look fine…

13

Everytime I update I run update&check DB…just to be clear, I only run EmonBase update cause I don’t have EmonPi.

14

Hmm, sorry about this, im none the wiser yet.

Could you try looking at the emoncms.log and apache/error.log while attempting to access the input page to see if we can get any clues there:

$ tail -f /var/log/emoncms.log

and:

$ tail -f /var/log/apache2/error.log

Could you also try the URL:

http://emonpi.local/emoncms/input/getinputs.json
15

Hi again @TrystanLea, I can only run the last one cause I don’t have any SSH access from outside:

{"emontx3":{"power1":{"id":"1","processList":"2:-1,3:-6,24:0,1:21,4:22,5:42,22:2,24:0,1:65,4:66,5:68"},"power2":{"id":"2","processList":"1:25,4:26,5:43,11:1,3:-6,24:0,1:59,4:60,5:69"},"power3":{"id":"3","processList":"1:27,4:28,5:44"},"power4":{"id":"4","processList":"24:0,1:29,4:30,5:45"},"vrms":{"id":"29","processList":""},"temp1":{"id":"30","processList":""},"temp2":{"id":"31","processList":""},"temp3":{"id":"32","processList":""},"temp4":{"id":"33","processList":""},"temp5":{"id":"34","processList":""},"temp6":{"id":"35","processList":""},"pulse":{"id":"36","processList":""},"rssi":{"id":"37","processList":""}},"emonth5":{"temperature":{"id":"14","processList":"1:33"},"humidity":{"id":"16","processList":"1:32"},"external temperature":{"id":"42","processList":""},"battery":{"id":"43","processList":""},"pulsecount":{"id":"44","processList":""},"rssi":{"id":"45","processList":""}},"emonth6":{"temperature":{"id":"20","processList":"1:34"},"humidity":{"id":"22","processList":"1:35"},"external temperature":{"id":"38","processList":""},"battery":{"id":"39","processList":""},"pulsecount":{"id":"40","processList":""},"rssi":{"id":"41","processList":""}}}

Later tonight I’ll run the other 2 commands

16

Is it likely to show any errors if “F12” is used in the browser?

17

@ivancaregnato that’s interesting, so just to confirm http://emonpi.local/emoncms/input/getinputs.json returns the above result and http://emonpi.local/emoncms/input/list.json returns a blank page?

18

Yes, I confirm blank page with list.json

19

Great, let me see id you find any errors in the above logs, hopefully that will highlight something.

20

Sure, I’ll reply later this night

21

I have made a change to the emoncms master branch that might solve this issue, are you able to pull in the latest master branch? The default emoncms branch on the emonbase/pi is stable, to switch to master the steps are:

cd /var/www/emoncms
git checkout master
git pull origin master

backup button is stolen :wink: - from admin :frowning: - how I can now backup the data ?
