DzVents stopped working [Solved]

[MartinManders]

Hey Guys,

I have a rather strange problem.
I've got 2 raspberry 2's serving Domoticz.

Both rasp 4.97 latest stable.
One with RFX (klikaan with 30 devices ) and one with Aeotec dongle (ZWave with 60 devices)
Python version 2.7.13 I checked.

Suddenly stopped the Dzvents stopped at the ZWave rasp.
Everything works fine except INTERNAL event system?
LUA scripts (externally works fine, but DzVents INTERNALLY nothing happens (it had worked clueless)

I checked (almost) everything but with no result.

I rebooted Domoticz, I rebooted the raspberry, no special errors?

As you see in naming the last script, my options are over ....

Somebody ideas?

Thanks

Martin

[emme]

have you already checked under SETTINGS/OTHER that LUA and DZVENTS are enabled?
did you change the main theme? some themes does not include the flag correctly

for dzVents... are there more script triggered by the same device?

ciao

[MartinManders]

Hey,

Thanks for your quick reply.
On both systems are LUA and DzVentz enabled.
If I share the function between the rasp's then one rasp acts on the event, the other doesn't.
(Same script) I copied it over and back....

[tonbor]

Any device name change, that happend to me once.

[MartinManders]

DzVents just reacts on a timer event, but not on a device event.
I just renamed the device in both systems, One does react, the other doesn't.

Tried with both systems, no luck ;-(

[emme]

can you please post a dzvents script?

[elmortero]

Might sound silly, but did the trick a while ago for me:
In settings I disabled dzvents and eventsystemen and enabled them again..

[MartinManders]

Hey Emme,

For this exercise I'm using a simple scripts, so there is no chance of naming issues etc..
I use this script on both Rpi's one works, one doesn't.

return {
on = {
devices = {
'KF1', 'KF3'
}
},
execute = function(domoticz, device)
domoticz.devices('Robin Spots').dimTo(50)
domoticz.log('Device ' .. device.name .. ' was changed', domoticz.LOG_INFO)
end
}

Might sound silly, but did the trick a while ago for me:

Sounded as something I haven't tried.
But also disabling en enabling didn't make the difference..

Hereby the logging from both systems when I stopped the Eventsystem:

The answer to your question is:

Status: EventSystem - Python: Failed dynamic library load, install the latest libpython3.x library that is available for your platform.

which lead to an already discovered problem with a (probably) solution

I tried updating the python version as discribed, now my system is totally down.

Domoticz off-line.
Tried several things (rebooting, updating domoticz), the domoticz service is running but no way to connect to the server?

Any idea's?

[emme]

You probably have python issues..
try to disable all plugins (rename plugin.py in each folder under /home/pi/domoticz/plugin )
if this does not fix then try
/home/pi/domoticz/updaterelease

ciao
M

P.S.
did you update/upgrade the PI via apt-get or rpiupdate ?

Hey goodmorning,

That was also my idea, but how to fix this?

I've renamed the plugin, start stopped, no luck.
I did again the ./updaterelease but also that doesn't fix the problem.

EDIT: I used apt-get to update

Thankx in advance

Martin

[emme]

can you please post the result for

sudo systemctl start domoticz

[MartinManders]

can you please post the result for

sudo systemctl start domoticz

Hai Emme,

pi@Meterkast:~/domoticz$ sudo systemctl start domoticz
pi@Meterkast:~/domoticz$

No result/error or working server ...
Or do you need some logging, and if yes, witch logging?

[MartinManders]

can you please post the result for

sudo systemctl start domoticz

At last I gave up. I had a recent backup, sow I installed a fresh Stretch, installed Domoticz fresh, updated/upgraded. And put my backup back to the new system. 10 minutes fingers crossed, and all my zwave devices are working.

Thanks for the advices, and remember; always make backups

I’ve been having dzvents problems that started today too. Not sure if they are related.

Everything was working fine until I edited some scripts this morning. I left them saved and enabled all day but with some syntax errors.Ive now fixed these errors.

The events system starts up ok, but some scripts resolutely refuse to be called on device events. I see the event in the logs, but the script isn’t called.

What makes it more weird is that it is inconsistent. I made identical copies of scripts, and enabled them alternately so that only a single one was enabled at a time. Some are called, and some not, and even worse, enabling and disabling them seems to change whether unrelated other scripts respond to their events or not. It makes no sense!

The Ras Pi has not be changed in any way for a number of days so I’m sure it’s not that.

Any suggestions? Database corruption? Luckily I have hourly/daily dB backups and full nightly system backups.

@Andyf66, just a thought ; if you got syntax errors and dzVents complained about them all day (to the log) and if your log is on the sd card ?
That excessive writing to the log might have caused the sd card to go bad.

Again just a thought...

Unlikely as it’s runing from an SSD drive via a USB->SATA adaptor. Nice idea though.

I’m going to restore a database backup in the morning to see how that goes, and if that fails I’ll roll back to a full system backup from the night before.
