Hi,

I just setup python module for the web power switch and wanted to run the sample code to turn off the a outlet.
Following is the code I am using:
from future import print_function
import dlipower

print('Connecting to a DLI PowerSwitch')
switch = dlipower.PowerSwitch(hostname="http://192.168.0.100/", userid="admin",password="1234")

print('Turning off the first outlet')
switch.off(1)

And following is the error log:

$ python HelloWebPowerSwitch.py
Connecting to a DLI PowerSwitch
Turning off the first outlet
Traceback (most recent call last):
File "HelloWebPowerSwitch.py", line 8, in
switch.off(1)
File "/usr/local/lib/python2.7/dist-packages/dlipower-0.7.152-py2.7.egg/dlipower/dlipower.py", line 341, in off
self.geturl(url='outlet?%d=OFF' % self.determine_outlet(outlet))
File "/usr/local/lib/python2.7/dist-packages/dlipower-0.7.152-py2.7.egg/dlipower/dlipower.py", line 311, in determine_outlet
if outlet_int <= 0 or outlet_int > self.len():
File "/usr/local/lib/python2.7/dist-packages/dlipower-0.7.152-py2.7.egg/dlipower/dlipower.py", line 188, in len
self.__len = len(self.statuslist())
TypeError: object of type 'NoneType' has no len()

I think the root cause it its unable to login the web power switch, hence erroring out when I try to access a outlet.

Kindly let me know, how I can fix this issue..

Thanks,
Sushant

Re-hello,

I discovered a strong issue with a test script that queries each outlet status forever.
After a random amount of time (between 1 and less than 5 minutes), the script is stuck for no apparent reason ☹️
Any idea ?

I even try to recreate the dqlipower.PowerSwitch object at each turn without better behavior...

I'm using the digitialloggers integration with Home Assistant (https://www.home-assistant.io/integrations/digitalloggers/), and it looks like it doesn't throw an exception on DNS lookup failures. The exception at the following line only catches exceptions from the requests module, it won't catch ConnectionError exceptions:
https://github.com/dwighthubbard/python-dlipower/blob/master/dlipower/dlipower.py#L416

There are several exceptions in requests that are not subclasses of RequestException: https://2.python-requests.org/en/v3.0.0/_modules/requests/exceptions/

When using dqlipower.py under Home Assistant (which should be based on 0.7.165), it is throwing the following error:

If I use the IP address instead of the hostname, that error goes away.

Hello,

First thank you very much for this very useful module !
Browsing your code, I believe the timeout setting is never passed to request.get(...)
Am I missing something here ?

I am trying to control the web socket switch from my python script - when running the script directly on the test system everything works fine as expected but when trying to trigger the same from Jenkins, the script is throwing 'Challenge' error when trying to open the connection.

All the other python modules works as expected.

Is there anything else needs to be handled or passed when running from Jenkins pipeline(Python script called from a Batch file)?

If there is a user setup on the switch with access to only 3 outlets (2,3 and 5 for example) then if you try to operate outlet 5 you get

File "C:\xxx\dlipower\dlipower.py", line 431, in determine_outlet
raise DLIPowerException('Outlet number %d out of range' % outlet_int)
dlipower.dlipower.DLIPowerException: Outlet number 5 out of range

It assumes because it can only see 3 outlets they should be numbered 1,2,3

The relevant variables are:

outlet =5
outlets=[[2, '4-2', 'ON'], [3, '4-3', 'ON'], [5, '4-5', 'ON']]
len=3

Without changing the code the only solution seems to be to use 'admin' user.

No handlers could be found for logger "dlipower.dlipower"

I'm trying to supplement the code with a logout function on my own. This code is a little above my skill level and was hoping you could tell me which packages and methods directly I'd need to write a logout method.

I see BeautifulSoup and urllib3 for web scraping, but I'm not sure how to activate the href for logout as they don't do direct clicking like Selenium would (from what I understand). The direct endpoint is http://192.168.0.100/logout on the default setup.

Once I finish I'd love to contribute it to the project.

Thank you,

I have a script that imports dlipower and runs on all of my hosts, but not all of my hosts have the webswitch installed on them. If a switch happens to be disconnected (or not connected at all), I get a big error when trying to connect to it. I noticed that there's a verify() method, but a call to that still generates the error. I also then tried running dlipower at the command prompt and it looks like specifying the wrong IP also generates an error. It would be really nice if the module would handle this a bit more gracefully, or at least make it so that the verify() method would handle this gracefully such that I can instantiate the class and call the verify() method to make sure the switch is available. Here's the output (I intentionally used the wrong IP to simulate a missing switch):

Would it be possible to get version tags that are the same as in PyPI?

PyPI package doesn't have the LICENSE.txt file. github does. FreeBSD ports would prefer it be there...

I expect dlipower set_outlet_name 1 foo-bar to set the outlet name to "foo-bar", but instead it throws this NameError exception:

$ dlipower set_outlet_name 1 "foo-bar"
Traceback (most recent call last):
  File "/home/.../dlipower", line 117, in <module>
    outlet_range = _block_to_list(','.join(args[1:]))
  File "/home/.../dlipower", line 49, in _block_to_list
    for value in outlet_range(int(val1), int(val2) + 1):
NameError: name 'outlet_range' is not defined

Setting to "foobar" works. I suspect the name is being interpreted as some kind of range but it's not clear how to escape the - character to avoid this behaviour.

Hi,
Just realized that non-admin users aren't able to rename outlets; spent some time wondering why set_outlet_name wasn't working though, so wanted to suggest some sort of warning when set_outlet_name is called by a non-admin user?
Thanks!

I am running below script. First of all, I did not find how to turn on all outputs from PowerSwitch object so that is why I am iterating through all outputs.
The issue is that when I run the script, I see about 3 second delay between each output turning on... I think it is processing time because I tried to change the sequency delay configuration on the DIN Relay unit to 0 seconds and still I got same results. So I wanted to ask if you have any suggestions?

import dlipower
rl1 = dlipower.PowerSwitch(hostname='192.168.0.100',password='1234')
for rl in rl1:
	rl.state='ON'

I was able to fix the issue by making slight modification in the file dlipower.py. I modified the line data = {'Username': 'admin', 'Password': m.hexdigest()} to data = {'Username': self.userid, 'Password': m.hexdigest()}. After making this change I was able to connect to the device and operate it

This line of code is causing an attibute error.

logger.debug('Response code: %s', request.status_code)

request is not guaranteed to have a value and so if the request fails, the code is trying to get the 'status_code' attribute of None which will result in an AttributeError exception being raised.

Example:

AttributeError: 'NoneType' object has no attribute 'status_code'

Something has apparently changed in the new LPC9 "pro" version of the switch (which also has wireless now) because the dlipower script won't connect to it.

If I do a curl against my old LPC7 switch, without authentication, I get this:

$ curl http://192.168.1.4/index.htm
<HTML><HEAD>

<META HTTP-EQUIV="refresh" content="0; URL=/">

</HEAD><BODY></BODY>

And if I include authentication, I get the actual index page (which dlipower would then parse). But with the LPC9, if I do a curl with (or without) authentication, I get this:

$ curl http://192.168.1.5/index.htm
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<link rel="stylesheet" type="text/css" href="/style.css">
<title>Redirecting...</title>

<META HTTP-EQUIV="refresh" content="0; URL=/">

</head>

<body>
</body>

</html>

It's not actually loading the index.htm page. Any suggestions on how I could fix this? The web UI of the LPC9 looks pretty much the same as the LPC7. It just has some additional features like wireless, event notifications, a new scripting engine, etc. The basic outlet control seems the same.

Thanks!

I developed a python 2.7 application that made use of this library (which was very helpful). However, the project recently switched to python 3.5. After the switch, we noticed that our switch no longer connected with the library. Instead:

>>> import dlipower
>>> switch = dlipower.PowerSwitch(hostname='ourhostname', userid='admin', password='*****')
>>> switch
Digital Loggers Web Powerswitch ourhostname (UNCONNECTED)

The library still behaves correctly if these same commands are used in 2.7.

I am seeing below message when I try to connect using dlipower.
dlipower.PowerSwitch(hostname="10.1.48.11", userid="admin", password="1234")
Digital Loggers Web Powerswitch 10.1.48.11 (UNCONNECTED)

Also on the server log below I see below error message for every attempt using dlipower module.
Jun 19 21:20:26 LPC970 user.notice auth[1494]: login denied for [email protected] (plaintext): password check failed
Jun 19 21:20:26 LPC970 user.notice www[1510]: login admin failed from 10.1.48.158

Any help on this would be much appreciated.

Hello

Unless Allow legacy plaintext login methods is enabled on the switch, authentication fails when attempting to login when using the following call from python:
dlipower.PowerSwitch(hostname=switch_hostname, userid=userid, password=password, use_https= use_https)

The switch reports the following:
Mon Nov 27 13:09:36 2023 user.notice auth[1525]: login denied for @ (plaintext): password check failed
Mon Nov 27 13:09:36 2023 user.notice www[2153]: login sect failed from
