Cynical Network: Parse Error

Hi There,

I'm using Cynical Network to interface with my HVAC. When I try to receive a temperature, I get an error like you see below. I think it's because the degree symbol is returned with the result. Is there anything I can do with the code to trap / fix the problem?

It should work like this...

Code: Select all

s1oat?
s1oat:050˚F


but I get this error...

Code: Select all

Anyone have any suggestions on other ways to tackle this problem, either with a different plugin that can access the Global Cache device, or by editing this plugin? I assume that filtering high-bit characters would fix the problem, but this particular script is quite complex and I really have no clue how to deal with it.

A bump. Nobody has any alternate ways to tackle this problem?

I've not seen many users using the Cynical Network plugin, which may be why nobody has replied.

I'm not overly familiar with XML, but are you able to print what xml is being returned (not just what your expecting)?

I'm not offering to fix this, but I will offer advice.

fist step you could try is to replace str() with unicode() in
indigo.variable.updateValue(self._variable(obj), str(value))


I guess you know how to edit the python code in a plugin: right click on plugin, show contents, go through directory , double-click on attr.py and find line 358 ..
and save, restart plugin

Hi Karl & thanks for looking at this for me! I made the change and did change the error message, so you've set me on the right track. Any thoughts on how to clear the UnicodeDecodeError: 'ascii' codec can't decode byte 0xb0 in position 8: ordinal not in range(128) error?

try value.encode('utf8') instead of unicode(value)..

or value.encode('utf8')

or unicode(value,'utf8')

one of those should do it . I believe..

Karl, you pointed me in the right direction!

I added the ignore errors keyword and that resolved the problem enough for me. Ignore is probably bad form, but it gets the job done.

Code: Select all

      indigo.variable.updateValue(self._variable(obj), unicode(value, errors="ignore"))


Thanks!

I'm having a similar error:

StandardError: ServerCommunicationError -- timeout waiting for response

  Cynical Network Error           plugin runConcurrentThread function returned or failed (will attempt again in 10 seconds)

I've tried

Code: Select all

   def __set__(self, obj, value):
      value.encode('utf8')   
      indigo.variable.updateValue(self._variable(obj), str(value))


but that doesn't seem to fix anything.

The string attempting to be sent is :

Code: Select all

SN2 M=OFF

Not sure why that would cause an issue but it does (only after a while. If I restart the plugin it works just fine.)

I'm not sure how to troubleshoot this issue. Again, if I click the plugin off, then on, it all works again, for an indescriminate amount of time. Any help or guidance appreciated (Python is not something I speak very well, though I am a programmer and can fudge my way around it). What would be ideal is for me to somehow be able to log what is being sent to this plugin and see which string(s) trip it up like Bollar was able to figure out...

By the way, when I change the same line that Bollar did too:

Code: Select all

      indigo.variable.updateValue(self._variable(obj), unicode(value, errors="ignore"))

I get the same error:

Code: Select all

  File ".../Server Plugin/cyin/attr.py", line 358, in __set__
    indigo.variable.updateValue(self._variable(obj), unicode(value, errors="ignore"))

For what it's worth, this is the code that ended up removing this issue for me:

Code: Select all

   def remove_non_ascii_1(self, text):
      return ''.join([i if ord(i) < 128 else ' ' for i in text])
      
   def __set__(self, obj, value):
      value2=self.remove_non_ascii_1(value)
      indigo.variable.updateValue(self._variable(obj), str(value2))


Basically it removes any non ASCII characters from the string before being set.
