EventWatcher[834] : Startup Lua Failed"

First I tried to install the version that is available in Vera App Store, but I got an error “EventWatcher[834] : Startup Lua Failed”"
Then I installed the version that is available in the Alternate UI App Store (version 16.7.6) but it give me the same error.

What should I do to get it working?
The only information that is available in Eventwather (under Control) is the following (everything else is empty):

  • Last Reboot
  • Last Luup Restart
    If I try to go open “Variable and Event log” it give the following error: No handler (http://my_IP/port_3480/data_request?id=lr_ALTUI_Handler&command=home&#)

A copy of the log whilst Vera is starting up should show some useful diagnostics.

My primary idea with getting Eventwatcher is to see what is in the logs :slight_smile:
Can you please tell me how to get what logs that you think can help to understand this issue?

EventWatcher doesn’t do that… it creates its own logs.

Can you please tell me how to get what logs that you think can help to understand this issue?

The easiest way is to open a browser to

http://VeraIP/cgi-bin/cmh/log.sh?Device=LuaUPnP

and watch whilst Vera starts up after a reload. After it settles down (maybe some time - the output is buffered) then copy the whole of the page contents (much of it scrolled off screen.)

Is it safe to publish the logs officially?

Depends whether you have any plugins or lock etc. with sensitive info. Otherwise, everything is behind you firewall. PM the log to me if that helps.

PM send.

Indeed the logs show an error:

The good news is that I understand that the condition that it reports would generate an error, the bad news is I simply cannot understand how that might happen. I’ve loaded the same version from GitHub onto both an openLuup development machine and one of my VeraLite machines and they both work perfectly.

There is, I suppose, the remote possibility of a download error. Can I ask that you re-install from the AltAppStore and try again?

First I installed the version located in the Vera App Store (same problem), then I have installed the version in Alternate App Store 8 times. Same problem, have tried to reboot.
Any other idea?

I have updated the version on the AltAppStore to the very latest (it’s what I run.) it’s v16.11.16.

Please try again from the AltAppStore.

Same problem…

Should I try a manual installation with WinSCP?
In this case, where do I find the latest files and where should i put them?

I used the files from github and put them all in cmh-ludl folder.
Tried again but still the same problem.

I noticed this in the log file: /etc/cmh/persist:

/etc/cmh/wan_failover:

What does it mean /dev/root and /dev/mtdblock9 has no available storage left?

OK, so we sorted all your problems…

  • the 0 free memory is standard for Vera’s ROM
  • the other issue was some uncompressed files from an old (manual?) install

As you asked, here’s a plot of the last day’s memory (in kilobytes, so 40K = 40 Mbyte), cpu, and uptime for the last month (only latest week showing so far.) You’ll see that my Veras stay up for a good long time without reloads (in fact, in this case, it’s just between power outages… we had one today.)

This is for 2x VeraLite with 64 Mbyte and 1x VeraEdge with 128 Mbyte. I believe your Plus has 256 Mbyte.

20% CPU seems standard for me, but YMMV.

Good luck!

Many thanks to akbooer for the fantastic support :slight_smile:
What plugin do you use for showing that diagram?

That’s Grafana, running on a Raspberry Pi, plotting data from a DataYours (Graphite) database.

I used Eventwatcher for several months on Vera3 on UI5 without any problems. Recently I upgraded to Veraplus with the latest firmware. Eventwatcher did work good first days but then I also got message as mentioned in the subject. Cannot find what’s the cause and how to solve it…

Which version of EventWatcher?

What does the log show?

Current Version:1.20140123

I looked at the logs after a restart. I see a lot of lines but nothing with EventWatcher in… Where do I have to look at ?

That’s massively out of date, and probably is only fit for UI5. Latest update was 20161116.

Would suggest first that you update all your files from here: https://github.com/akbooer/EventWatcher

and then see what happens.

I just downloaded it from the appstore and this was the version I got.

Well I followed your instructions and updated the 5 files via develop apps -> luup files -> upload & restart Luup after upload. The strange thing is: I still am on the same version number and I still have the lua startup error …
