script for polling sma webbox - help getting variables

hi all. i'm trying to get variables from a script into indigo, anyone have a moment to help with this? i'm sure it's simple, i just don't know it!

the link below is the post with the script, the return, and the question --- thanks so much in advance!

See my reply in the other thread and let me know if you have any questions.

(reposted from other forum, will move discussion here)


great dave! thanks

i've got that part, the python variables for indigo, so, the syntax for setting a value string from the script to indigo var is:

for Pac:
#indigo.variables[1958563501] # "PV_Pac"


something like, but correctly done??:

indigo.variable.updateValue(1958563501, Pac)

? will this work? or is the syntax different. i'm trying it..

thanks again!

so that gets me this when i run the script in indigo:

Schedule sma webbox update
Action Group sma webbox poll
Script Error webbox_poll.py: global name 'Pac' is not defined
Script Error Exception Traceback (most recent call shown last):

webbox_poll.py, line 217, at top level
NameError: global name 'Pac' is not defined

how do i set an indigo variable to the value of a variable that is a result of the script and not a string?


thanks!

Need to see your work.

Sounds like Python is telling you that the script doesn't have access to the value where you're asking for it. Likely a small problem.

yes. not sure how to get the variable that results Pac from the script into an indigo var. does it need to be more the form of:

Code: Select all

indigo.variable.updateValue(1958563501, (value of variable "Pac" as string))


the section i'm using is this, but none of it working yet:

Code: Select all

#     indigo.variables[1822257245] # "PV_EToday"
#   indigo.variables[1469286291] # "PV_ETotal"
#   indigo.variables[789149473] # "PV_Mode"
#     indigo.variables[1958563501] # "PV_Pac"
               
               
indigo.variable.updateValue(1958563501, (value of variable "Pac" as string))
indigo.variable.updateValue(789149473, Mode)
indigo.variable.updateValue(1469286291, GriEgyTot)
indigo.variable.updateValue(1822257245, GriEgyTdy)
               
# indigo.server.log("The variable had a value of 'true'")

the values i'm looking for are part of the GetPlantOverview, and GetProcessData calls. not sure how to parse them to access as individual variable values.

You can turn something into a string by recasting it. There are things that can't be recast, but you're probably okay here.

Code: Select all

string_value = str(value)

indigo.variable.updateValue(1958563501, str(value of variable "Pac" as string))


But that doesn't address your global value issue. This is an example of where that' can occur:

Code: Select all

x = 2

def thing():
    y = x * 2


Python wants variables inside functions to be local to the function. You can get around that by declaring them as global.

Code: Select all

x = 2

def thing():
    global x
    y = x * 2


i global-ed, and tried, but:

Code: Select all

Script Error                    webbox_poll.py: invalid syntax
   Script Error                    around line 222 - "indigo.variable.updateValue(1958563501, str(value of variable "Pac" as string))"


it doesn't like that either. i keep digging around the python scripting hints in the wiki, but can't quite figure it....

Code: Select all

 Script Error                    webbox_poll.py: global name 'Pac' is not defined
   Script Error                    Exception Traceback (most recent call shown last):

     webbox_poll.py, line 219, at top level
NameError: global name 'Pac' is not defined

got that with trying (Pac) without the 'value of variable' ... still throwing error.


thanks a lot for the help dave.

thanks a lot for the help everyone.

finally after years of not doing it i've got the solar array current power and daily total on the main control page - much needed !

power in yellow in pool, daily total at bottom left of page.

thanks again, much appreciated.

sorry about the image scale. i downrezzed to allow for upload but i guess the size is still huge. at any rate. there we are.

Sorry dtitch, never saw this thread which is why I kept responding in the other one.

It's worth leaving it in Dave's plugin forum but I'll see if Jay can mod it once I've asked Dave.
