Any thoughts/solutions/etc most appreciated. Thanks.

Has anything changed on your system? Did you update the thermostat firmware? Which version if Indigo and the plugin are you running?

Re: Proliphix™ Plugin Discussion

Thank you for your reply.

The only thing that changed, to the best of my knowledge, was the update to OSX 10.9.3. Nothing changed on the thermostat end. Yesterday, when the problem started, I was running Indigo 6.0.11 - as of this AM, I'm running 6.0.12. I'm running Proliphix Thermostat 1.9.8, and have been for a while.

I'm also seeing these with some regularity:

Code: Select all
  Proliphix Thermostat Error      writeTstat: The device GI Upstairs Proliphix at "blah.axiscam.net" could not fulfill the request. Reason = HTTP Error 401: Authorization Required

Re: Proliphix™ Plugin Discussion

Let me also point out that the plugin does seem to be functioning - I'm still seeing updates from the therms.

Re: Proliphix™ Plugin Discussion

I have observed the same authentication problem myself with one of my 2 NT20s. But, not the other. I have not been able to track down the cause of the problem.

I will look into the other issue you reported and see what I can find. Which model thermostat do you have?

Re: Proliphix™ Plugin Discussion

I have two - an NT150e and an NT10e. It's the NT10e that is throwing the "writeTstat: The device GI Upstairs Proliphix at "blah.axiscam.net" could not fulfill the request. Reason = HTTP Error 503: Service Unavailable" error.

Re: Proliphix™ Plugin Discussion

Nothing so far. It is pretty hard to track down a problem I can't duplicate. And even when I can, like the "writetstat" error, the problems seem to point to something in the stat not the plugin. But, I am still looking.

I need to do a complete re-write on this plugin. It was my first attempt and I have learned a lot since then.

I probably should have provided a bit more response to this question. The errors are being thrown in urllib2 a standard Python module that is called by the plugin. Based on the error messages you have posted, an authentication error is taking place.

If this error occurred on every attempt, on every stat, it would point to a change in the firmware. But, I just can't figure out why this would happen some of the time?

I guess it is time to give their tech support team a call.

Could it just be this??:


Proliphix devices implement the Basic Access Authentication protocol specified in RFC 2617. All queries must provide proper credentials based upon the admin username/password pair. The device implements a timeout mechanism such that 20 minutes after the last successful access, the user is required to resend authentication information. This will come in the form of a 401 response even if proper credentials were sent in the current request.

Thanks for the idea, but... probably not the cause of the problem. The plugin does a complete basic authentication on every attempt to write to the tstat.

For those that are interested, here is the code from writeTstat (the errors are occurring at f = urlopen(theUrl):
Code: Select all
      ######################################
        # create a password manager (This should be in a separate function)
        password_mgr = urllib2.HTTPPasswordMgrWithDefaultRealm()

        # Add the username and password.
        # If we knew the realm, we could use it instead of None.
        password_mgr.add_password(None, theUrl, user, passw)

        typeKey = model[0:2]
        if typeKey == "NT":
            # NT Devices use basic auth
            handler = urllib2.HTTPBasicAuthHandler(password_mgr)
            if self.logLevel > 2: self.debugLog('writeTstat: Using Basic auth for type key: %s' % (typeKey))
        else:           
            # Since it's not an NT, it must be an IMT, and we use digest auth
            handler = urllib2.HTTPDigestAuthHandler(password_mgr)
            if self.logLevel > 2: self.debugLog("writeTstat: Using Digest auth for type key: %s" % (typeKey))
        # create "opener" (OpenerDirector instance)
        opener = urllib2.build_opener(handler)
        urllib2.install_opener(opener)
        #######################################

        try:
            # req = Request(theUrl)
            f = urlopen(theUrl)     
        except URLError, e:
            # errorsDict = indigo.Dict()
            if hasattr(e, 'reason'):
                self.errorLog("writeTstat: Failed to reach device \"%s\" at %s. Reason = %s" % (device.name, address, e))
            elif hasattr(e, 'code'):
                self.errorLog("writeTstat: The device %s at \"%s\" could not fulfill the request. Reason = %s" % (device.name, address, e))       
            return

New beta available

I have made some changes in the way the authentication is managed. Rather than creating a new password manager on each query, a common manager is now created for all stats. Also, a specific handler is now created for each device in advance, and then re-used. So far I have not seen anymore writeTstat write errors. I have not been able to reproduce the other error reported by @HFTobeason, so I don't know if this update will address that issue.

Version 1.9.9 of the Proliphx plugin is available on dropbox.

Re: Proliphix™ Plugin Discussion

I'm not entirely certain why, but I'm no longer seeing any of the errors I reported. I'm running the 1.9.9 plugin as of yesterday, but the errors had tapered off a day or two prior. It's all just a mystery...

Re: Proliphix™ Plugin Discussion

Hi All,
I'm now to Indigo and I've got 4 Proliphix NT10e's that I would like to keep using, if possible. I'm using v1.9.9 of the plugin on Yosemite. At startup, things seem to be OK:

Code: Select all
Nov 30, 2014, 4:19:10 AM
  Starting Indigo Server version 6.0.18 (Mac OS X 10.10.1)

  Loading plugin "Proliphix Thermostat 1.9.9"
  Starting plugin "Proliphix Thermostat 1.9.9" (pid 25607)

  Proliphix Thermostat            Log level preferences are set to "Normal".

  Started plugin "Proliphix Thermostat 1.9.9"
  Proliphix Thermostat            Plugin Starting
  Proliphix Thermostat            Your plugin version, v1.9.9, is current.
  Proliphix Thermostat            Starting device Hall Thermostat

  Proliphix Thermostat            Starting device Master Thermostat
  Proliphix Thermostat            Starting device Studio Thermostat
  Proliphix Thermostat            Plugin started. Polling thermostats every 5.0 minutes with a 8.0 second timeout



The log is full of these errors:
Nov 30, 2014, 4:34:15 AM

Code: Select all
Proliphix Thermostat Error      readTstat: The device XXXXX Thermostat at "192.168.1.11" could not fulfill the request. Reason = HTTP Error 401: basic auth failed
  Proliphix Thermostat Error      readTstat: The device XXXX Thermostat at "192.168.1.22" could not fulfill the request. Reason = HTTP Error 401: basic auth failed
  Proliphix Thermostat Error      readTstat: The device XXXXX Thermostat at "192.168.1.14" could not fulfill the request. Reason = HTTP Error 401: basic auth failed


I'm sure that the credentials are correct, because I notice you can't get past the configuration dialog with bad credential.

Additionally, If I increase the log level and grab the URL, I am able to get successfully retrieve the data in the browser and I don't get a 401.

Also, If I restart the server, and I'm able to work through the app for maybe a minute, and then the 401 start coming. Even after openurl() returns 401s, putting the same URL in the browser works fine.

Any ideas on what might be the issue here?

Re: Proliphix™ Plugin Discussion

An update to my previous comment.
When I wiresharked, I couldn't find the authorization in the header, so I made the change below to the plugin.py file to make sure it gets in there each time. There are two changes, one for the read and one for the write.

So far this seems to be working:
Code: Select all
21d20
< import base64
282,284c281
<         req = urllib2.Request(theUrl);
<         base64string = base64.encodestring('%s:%s' % (user, passw)).replace('\n', '')
<         req.add_header("Authorization", "Basic %s" % base64string)
---
>
287c284
<             f = urlopen(req)     
---
>             f = urlopen(theUrl)     
377,379d373
<         req = urllib2.Request(theUrl);
<         base64string = base64.encodestring('%s:%s' % (user, passw)).replace('\n', '')
<         req.add_header("Authorization", "Basic %s" % base64string)
382c376,377
<             f = urlopen(req)
---
>             # req = Request(theUrl)
>             f = urlopen(theUrl)


I'm sure this isn't the most elegant solution, but it gets me up and running for now.
