Indigo Domotics

So I'm not the best at Python, but the following error came up and I'm not sure why..

If the SceneON is listed as

Code: Select all

 indigo.insteon.sendSceneOn(7)

it won't run, but will if listed as

Code: Select all

 indigo.insteon.sendSceneOn(07)

However this DOESN'T run

Code: Select all

 indigo.insteon.sendSceneOn(08)

but

Code: Select all

 indigo.insteon.sendSceneOn(8)

does.


The error I got was

Script Error embedded script: invalid token
Script Error around line 6 - "indigo.actionGroup.execute(1541175388),indigo.insteon.sendSceneOff(08)"


I'm not going to loose any sleep over this but was more curious as to why one has to be formatted WITH the preceding zero, and the other doesn't....

Any ideas ?

I don't think the prefix 0 is the problem. From the look of the error message, it looks like there might be a formatting problem with your script. It looks like Indigo doesn't think there is a line break between the action group execution line and the insteon sendSceneOff line?

Another issue to be aware of is that in Python 2.7, a leading zero indicates an octal integer. So 07 is legal, 08 is not.

FWIW, I actually just coped the 1st line and pasted into the "else:" option, and changed the scene # to 08, and got the same error message... changing it from "08" to just "8" makes the error message go away... Likewise, changing the 1st line from "07" to "08" introduced the same error message... but going to just "8" made it go away.

Code: Select all

dev = indigo.devices[120542152] # "KeypadLinc"
if (dev.ledStates[2] == True):
   
   indigo.actionGroup.execute(339158514), indigo.insteon.sendSceneOn(07)
else:
   indigo.actionGroup.execute(339158514), indigo.insteon.sendSceneOn(08

It's the octal specifier mentioned by FlyingDiver above. Literals that start with a zero are interpreted as octal values and 08 is an invalid octal number.

Note that this is Python 2.x only. Which Indigo uses. Python 3 requires the use of the "0o" or "0O" prefix (zero-Oh).

IMO, it was a terrible idea in Python 2.x to do that. The Python 3 way is much better.

Unfortunately, I believe it's still in Python 3 for backwards compatibility...

Other way around, I think. 2 would take either, 3 will only take "0o". The leading zero was a nod towards a number of other languages which do the same thing. I think it started with C.

From a non-coder point of view, I do find it amusing that sometimes the simplest things are complicated... In the end, this was an easy hurdle for me to get over as I knew that the code worked in some instances. Past that, it was just a matter of experimenting 'til I came up with the right answer, and there were only 2 options... , but can easily understand that others my find this maddening..
