Curl command returns values; Network Resources does not

[pjjameso]

Im sure its my not understanding how the network resources works so seeking some advice.  My test curl command works and sends back the correct information as seen below . However when i try and set this up in the network resources all I get is an Request Fail, N/A, what am i doing wrong?

Of course my next question will be how do I parse the information returned and populate state variables with the data....?

Did you check the Use SNI box?

If not, try that.

Unfortunately, you cannot do this. Network Resources on ISY are for triggering events. You cannot extract data from the calls you make.

[pjjameso]

Just tried your SNI suggestion, no luck so far.

[pjjameso]

Dang, just read your second paragraph.... so how would one make an api call to a website to retrieve data and then populate state variables?  Currently using IFTTT, but the polling is only once per hour, was looking for something a bit more robust.

Depending on your skill set, one could create an cloud space someplace to do the processing.  a middleman of sorts.   State variables can be set via the Portal API or through the ISY API with open port.  You'd have to do all the programs there, probably via something like php.

...or actually the same on a local machine such as an RPI....

Similar to Mr. Bill's suggestion, if you are a developer you could also look into creating a Node Server for Kaiterra.

[pjjameso]

Oh boy! Been reading the documentation…..think I will need to pay someone to create the node server at some point. Probably too old at this point to learn how to write the code. ?

[sjenkins]

You are advanced enough to use curl, that says you know enough.
Start small and inch your way there.
The cleanest way is a node server for sure but there are other ways to skin the cat (I am old too btw: ).
Write a script with curl and then use the ISY REST to write your variable. Then have your script run as a service on a desktop or a raspberry pi triggered regularly. I did this before the nodes were a thing then finally took a look at a few node server examples and made first some changes to others then my own node.

@pjjameso and @sjenkins

There are also "blank" nodeserver templates in the store... see PythonTemplate and NodejsTemplate.

[pjjameso]

Thank you for pointing to the templates and instructions, will give it a go! Will most likely be back with more questions.
