Python Plugin: PiMonitor Topic is solved

[Solderbro]

Hello,

maybe this is related to raspbian buster stable. On every cold start or reboot i got a mail and found this in the log.

2019-07-22 17:41:50.351 Error: (RPI_Monitor) 'onStart' failed 'KeyError'.

Is it a problem that 2.7 and 3.7 is installed?

@Solderbro

The

Code: Select all

onStart' failed 'KeyError'.

has nothing to do with the raspbian buster or Python versions. In the past I had the same problem, and is related to the name of the images. Probably this name gives a problem in Domoticz. It gives only an error at startup, but your devices will work.
Are you using the latest version of PiMonitor?

[Solderbro]

Yes after the error everything else look fine. Using the version from 19. of july what seems to be the lastest one.

Thanks

Hi everybody
I have the same problem:

2019-07-22 17:41:50.351 Error: (RPI_Monitor) 'onStart' failed 'KeyError'.
2019-07-22 17:41:50.351 Error: (RPI_Monitor) ----> Line 332 in '/home/pi/domoticz/plugins/Domoticz-PiMonitor-Plugin/plugin.py'

Domoticz V4.10717
Raspian Buster
Python 3.7.3

[Xorfor]

This

Code: Select all

onStart' failed 'KeyError'

is only at startup of the plugin. It has to do with loading the images. I didn't find a reason why Domoticz gives this message and I can not reproduce this on my RPi. But you will see that you only gets this message once and that the plugin works fine.

Hi everybody
I have the same problem:

Domoticz V4.10717
Raspian Buster
Python 3.7.3

I modify plugin.py in line 152 -164, and it run OK!

Code: Select all

   
   
    #    if "xfrpimonitor" not in Images:
    #        Domoticz.Image("xfrpimonitor.zip").Create()
    #    image = Images["xfrpimonitor"].ID
    #    Domoticz.Debug("Image created. ID: "+str(image))
        # Create devices
        if len(Devices) == 0:
            for unit in self.__UNITS:
                Domoticz.Device(Unit=unit[0],
                                Name=unit[1],
                                Type=unit[2],
                                Subtype=unit[3],
                                Options=unit[4],
                                Used=unit[5]).Create()

I installed it without problems on a PiZero where my Domoticz is running on presently.
What I find strange is that I see 17 tiles in the Utility screen but only 7 devices in the setup-device screen.

Furthermore I see (after a wile) this error message

Code: Select all

2019-12-08 15:53:33.302 Error: Pi hardware (12) thread seems to have ended unexpectedly

How come?

[fabd]

Hello

Could we imagine adding a switch to monitor latency to the router (for example) ?

[Xorfor]

Added device to monitor latency. The plugin will try to find the gateway, will send a ping to the gateway and retrieves the latency time.

Hi,

I've installed domoticz-remote-Pi-Monitor on my pi and the plugin on my domoticz server.

In domoticz i've put the ip of the other pi and in the remote pi, i've put the ip of my domoticz server.

Then i get this message:

15:06:35.513 Error: (PiReMonitor) 'onHeartbeat' failed 'ConnectionRefusedError'.
2020-01-23 15:06:35.513 Error: (PiReMonitor) ----> Line 295 in '/home/pi/domoticz/plugins/domoticz-remote-Pi-Monitor/plugin.py', function onHeartbeat

Any idea what's wrong ?

[nosehook]

Ik recently got these errors in my log:

Code: Select all

2020-05-05 12:29:27.907 Error: (PiMonitor) 'onHeartbeat' failed 'TypeError':''NoneType' object is not subscriptable'.

2020-05-05 12:29:27.907 Error: (PiMonitor) ----> Line 304 in '/home/pi/domoticz/plugins/xfr-pimonitor/plugin.py', function onHeartbeat

No clue how to solve it though, can anyone give me some pointers?

[Geitje]

Did you update to the most recent version of Pimonitor?

[Chris12]

Hi, it looks like that this plugin is no longer maintained.. too bad
https://github.com/Xorfor/Domoticz-PiMonitor-Plugin

But I found an other one based on the above plugin, which even does exactly what I want: monitoring of a remote Rpi (which runs Pi-Hole)
https://github.com/JVaassen/domoticz-remote-Pi-Monitor

But as I'm a kind of noob regarding Rpi and the installation of packages, I'm kind of stuck how to install this plugin.
How do I do these steps:
1.Install the python script in /usr/bin on remote server.
2.Install piremotemonitor in /etc/init.d on remote server.


The domoticz part I get ( i hope so) for installing on my Synology I have to do:
#cd /volume1/@appstore/domoticz/var/plugins
#sudo git clone https://github.com/JVaassen/domoticz-re ... onitor.git
restart domoticz via synology webGUI

Or do I first have to install the PiMonitor itself as well?

Anybody here who can help me a little bit?

[Chris12]

I have installed the PiRemoteMonitor according to the steps described.

But after restarting domoticz I see an error:

2021-01-21 12:11:34.295 Status: (PiRemoteMonitor) Started.

The log file /var/log/PiRemoteMonitor.log (found on the Pi remote server) does not show any error.
Show somehow the lxml module is not working on my synology.

On my synology when running:
# python3 -m pip install python3-lxml
ERROR: Could not find a version that satisfies the requirement python3-lxml
ERROR: No matching distribution found for python3-lxml

On my synology the follwoing does not work:
sudo apt-get install python3-lxml

Not have found a sollution for this yet.
