Adding and Averaging Variables in Python.

So I've got some variable in Indigo, bring them into a Python script, and need to list them, add them, and average them, and send out via email. When I run the math part in Terminal, it works fine...

Code: Select all

>>> theVar1 = 1
>>> theVar2 = 2
>>> theVar3 = 3
>>> theSum = theVar1+theVar2+theVar3
>>> theAvg = theSum/3
>>>
>>> print theSum, theAvg
6 2
>>>

But the best I can get for adding them together in Indigo is not 1+2+3 = 6, but just the numbers sequentially - 123. And nothing I've tried for the average has worked. I have consulted this page
http://wiki.indigodomo.com/doku.php?id= ... g_tutorial
which was very helpful in getting just the listing and the emailing done properly, but don't see anything that relates to the math with the variables I'm trying to do here. I've listed a few of the things I've tried for both theSum and theAvg, but, as I said, so far, nothing.

I even tried for theSum using

Code: Select all

theSum1 = indigo.variables[2343]+indigo.variables[45643]

but that didn't work either..


Hoping this is an easy one to solve.....

This is the current script, with a few variations, which don't work..

Code: Select all

# Listing variables, adding together, averaging, and emailing
theVar1 = indigo.variables[203610088]
theVar2 = indigo.variables[1949474627]
theVar3 = indigo.variables[1721091434]

theSum1 = (theVar1.value)+(theVar2.value)+(theVar3.value)
theSum2 = theVar1.value+theVar2.value+theVar3.value

theAvg1 = theSum1/3
theAvg2 = (theSum1)/3
theAvg3 = theSum1.value/3



theSubject = "Indigo Variables"
theBody = "The Variable #1 is %s\n The Variable #2 is %s\nThe Total is %s/n the Average is %s" % (theVar1.value, theVar2.value, theSum1, theAvg1)
indigo.server.sendEmailTo("jltnol@xyz.com", subject=theSubject, body=theBody)

Try:

Code: Select all

# Listing variables, adding together, averaging, and emailing
theVar1 = indigo.variables[203610088]
theVar2 = indigo.variables[1949474627]
theVar3 = indigo.variables[1721091434]

theSum = int(theVar1.value)+int(theVar2.value)+int(theVar3.value)

theAvg = theSum1/3.0




theSubject = "Indigo Variables"
theBody = "The Variable #1 is %s\n The Variable #2 is %s\nThe Total is %s/n the Average is %s" % (theVar1.value, theVar2.value, theSum, theAvg)
indigo.server.sendEmailTo("jltnol@xyz.com", subject=theSubject, body=theBody)


You need to convert from strings to integers. Or maybe floats, depending on what those values really are.

BEAUTIFUL!!

This line kicked out during compile, but was super easy to spot, change, and fix!

Code: Select all

theAvg = theSum1/3.0

should have been

Code: Select all

theAvg = theSum/3.0

Once again... THANKS!!

I need to add several "current loads" from different Fibaro wall plugs, I tried the script as mentioned above but it returns an error, it does not recognize the key id from my wall plugs.
How do I address the current load and total load from these wall plugs? where do I specify that I need this particular data?

Hope anyone can help

See this documentation

Sample code for two devices:

Code: Select all

calculated = (indigo.devices[12345678].energyCurLevel + indigo.devices[87654321].energyCurLevel) / 2
indigo.server.log(u'TEST VALUE = %s' % (str(calculated)))

Use energyAccumTotal instead of energyCurLevel for the total accumulated load.
Just substitute your device Ids for the 12345678 and 87654321 numbers.

Hope this helps

Thanks a lot Jon, works perfect!
Question: How do I discover the names of the variables like "energyCurLevel"
Is there a place I can find these parameters?

Yes - the first line of my previous response - the documentation link

EDIT: Device Base Class Properties

Thanks a lot, that has been very helpful !

Is it possible to gent Energy Level in apple script?

[jay (support)]

AppleScript doesn't have access to the energy fields, but you can use the Insert Device State into Variable action whenever the energy field you're interested in changes so that you can get the value from the variable in AppleScript.

How about some help for a Python newbie on this one:

I'm trying to take an average of 6 Variables and write them back to another Variable in Indigo.

Code: Select all

# Listing variables, adding together, averaging.
theVar1 = indigo.variables[895595021]
theVar2 = indigo.variables[1244034327]
theVar3 = indigo.variables[545475570]
theVar4 = indigo.variables[1191740502]
theVar5 = indigo.variables[142629916]
theVar6 = indigo.variables[1877833097]
theSum = int(theVar1.value)+int(theVar2.value)+int(theVar3.value)+int(theVar4.value)+int(theVar5.value)+int(theVar6.value)
theAvg = theSum/6.0
indigo.variable.updateValue(59002876, theAvg) # Write the updated value back to Indigo

Script fails on line 10, trying to write the average back to a variable.

Code: Select all

 Script Error                    embedded script: Python argument types in
    VariableCmds.updateValue(VariableCmds, int, float)

Thanks in advance!

All Indigo variables are stored as strings, even if they look like an int or float - see Indigo Variable Documentation

So you need to change the line:

Code: Select all

theAvg = theSum/6.0

to

Code: Select all

theAvg = str(theSum/6.0)

Hope this helps

Thanks Jon!! Works perfect!

Now I have a master volume value for my 6 Airfoil Volumes!

I have another one, I just cam't figure out why it's not working.

I want to extract one variable value from another and put the result in a third variable.

theVar1 = indigo.variables[258092774]
theVar2 = indigo.variables[1797074476]

theDif = str(theVar1.value)-str(theVar2.value)

indigo.variable.updateValue(783072313,'%s kWh' % ((theDif)))

When I replace the - for a plus it does update the variable theDif but displays in this variable the value of theVar1 and theVar2 together
When I use the - operand it returns an error. It is probably something with the value of the indigo.variables but I can't find it.

Anyone an idea?

You need to pay attention to when the data is in string form vs integer form.

Code: Select all

theVar1 = indigo.variables[258092774]
theVar2 = indigo.variables[1797074476]

theDif =str( int(theVar1.value) - int(theVar2.value))

indigo.variable.updateValue(783072313,'%s kWh' % ((theDif)))
