Domoticz

Posted: **Sunday 08 January 2023 16:31**

Today I noticed that my python script on domoticz was not running anymore with no obvious reason (I have not touch it for a while). After trying to understand the problem I noticed that even a very simple code is not working at all

Code: Select all

import DomoticzEvents as DE
import re

es=list(map(float,re.findall("(\d+\.?\d+);(\d+);(\d+)",DE.Devices['Temp Chambre'].s_value)[0]))
DE.Log("Python:"+str(es))

def data_meteo(name):
    return list(map(float,re.findall("(\d+\.?\d+);(\d+);(\d+)",DE.Devices[name].s_value)[0]))
    
dat=data_meteo('Temp Chambre')

DE.Log("Python:"+str(dat))

In the log here is the output that I get

Code: Select all

 2023-01-08 15:28:23.348 Python:[17.7, 75.0, 3.0]
2023-01-08 15:28:23.350 Error: Traceback (most recent call last):

2023-01-08 15:28:23.351 Error: NameError: name 're' is not defined

I do not understand what happens. Maybe the version of python used by my system changes? Anyone can help me?

What is menu setup - about saying about python?
The error is about module "re" (regex expressions) wich i think is a standard installed module so not sure what is going on...

I am sorry I do not get it, what do you mean exactly?

Yes, you are right, the error is about the module "re". But please note that I call twice the same command (line 4 and line 10). The first time I call it, in line 4, it gives the correct output:

Code: Select all

 2023-01-08 15:28:23.348 Python:[17.7, 75.0, 3.0]

The second time I call it (inside a function) it gives the error. It is very strange.

What is the python version Domoticz is using? You see that in menu setup - about. Or at startup in the logging of Domoticz...

That's "Python Version: 3.7.3 (default, Oct 31 2022, 14:04:00) [GCC 8.3.0]"

Ok, that seems a very well supported version. No idea what happened on your side...

To check if the problem comes from python I also try to run the same code directly with python3.7 on my rapsberry.
I ran the following code on my raspberry using python3.7

Code: Select all

import re
es=re.findall("(\d+\.?\d+);(\d+);(\d+)","18.4;75;3")
print(es)

def ret(dev):
    return re.findall("(\d+\.?\d+);(\d+);(\d+)","18.4;75;3")
    
print(ret('Temp Chambre'))

It works fine and gives me the output

Code: Select all

[('18.4', '75', '3')]
[('18.4', '75', '3')]

On the other hand on domoticz

Code: Select all

import DomoticzEvents as DE
import re

DE.Log("Python:"+str(re.findall("(\d+\.?\d+);(\d+);(\d+)","18.4;75;3")))

def ret(dev):
    return re.findall("(\d+\.?\d+);(\d+);(\d+)","18.4;75;3")
    
ret('Temp Chambre')

and it gives me the following output in the log file

Code: Select all

2023-01-08 21:49:41.293 Python:[('18.4', '75', '3')]
2023-01-08 21:49:41.295 Error: Traceback (most recent call last):
2023-01-08 21:49:41.295 Error: File "Script #1", line 9, in <module>
2023-01-08 21:49:41.295 Error: File "Script #1", line 7, in ret
2023-01-08 21:49:41.295 Error: NameError: name 're' is not defined

The first command with "re" works fine in domoticz but not when it is inside the function "ret", it is very strange. I do not get why

I don't understand it either, looks like a bug, but if it worked before and now no longer it is not a program error and the key question is: When did it stop working and what happened shortly before it? Can you find it in the logfile? Maybe related to an upgrade?

Yes I have the logfile and know when it stopped working. I copy the log file below:

at 13:31 it was working fine and then it stops. When it restarted at 13:32 errors started to appear. I am not sure why it stops.
I know I have been updating my raspberry pi this week but I am not sure it was at this particular moment. I tried to investigate when it was using this page https://serverfault.com/questions/20747 ... th-apt-get and I ended up using the following command

Code: Select all

ls -lt --time-style="long-iso" /var/log/apt

I obtained the output

It seems to be the list of dates when I updated my raspberry pi, but I am not totally sure. Can you confirm? If it is, then the date of the restart in the logfile and the date of update do not agree.

I can't offer you a conclusion unfortunately but it seems you made a connection (incoming connecting ....) and then forced a restart. I assume it was for a reason .....?

Posted: **Monday 09 January 2023 15:06**

I assume it was for a reason .....?

I cannot remember making a connection this day. I initially thought it was the raspberry pi update but we saw that is was not on the same day. So I don't know

The only thing I can imagine is that I inadvertently updated my version of domoticz. I was avoiding the update since several months because it gave me an error (see this post viewtopic.php?t=37962&sid=bfc423208e79f ... ef46890633). However, it is easy to click on the update button by mistake and now I notice that domoticz does not propose me to update: so I guess I am in the last version, what do you think?
It is written on the domoticz page that I am in the
Version: 2022.2
Build Hash: eea9db734
Compile Date: 2022-11-05 12:05:35
If it is the last version, the good point is that the old error ("Segmentation fault") that I had does not appear anymore. Obviously the bad point is this new crazy error. What do you think? Many thanks for trying to help me

Posted: **Monday 09 January 2023 15:53**

Yes, that's the same latest version that I use. I tried running your small piece of code but apparently I don't have DomoticzEvents installed since the import fails.

Posted: **Tuesday 10 January 2023 22:47**

Any news? any help? I really need my code, it controls everything in my house and avoid the circuit breaker to trip.
Many thanks

Posted: **Wednesday 11 January 2023 0:45**

I recall a problem I had before with python plugins where the import acted weird every now and then. Dnpwwo suggested to debug by adding a try statement before the import but cannot recall what my resolution was. I think it eas down to a package update which messed up the import. Will look it up tomorrow hoping I can still find it.

Since the cause is not clear, I would take a new SD card, re-install everything, copy the dbase and scripts and see whether it is solved ...

Could you solve it using this command?

Code: Select all

sudo pip3 install requests

it seems you miss this module.

I did as you suggest: I took a different card, I installed "pi-lite", I installed domoticz, I installed python on the pi and when testing the same code as in the beginning of this post:

Code: Select all

import DomoticzEvents as DE
import re

es=list(map(float,re.findall("(\d+\.?\d+);(\d+);(\d+)",DE.Devices['Temp Chambre'].s_value)[0]))
DE.Log("Python:"+str(es))

def data_meteo(name):
    return list(map(float,re.findall("(\d+\.?\d+);(\d+);(\d+)",DE.Devices[name].s_value)[0]))
    
dat=data_meteo('Temp Chambre')

DE.Log("Python:"+str(dat))

I obtain again the same error

No, I did not know it was the next step in the process. Thanks.
However I am not sure how to do it, any advise? I will try tomorrow
