Variable History?

[Jamison_IO]

I looked at the log and it doesn't appear to be there.

 

I know I can open up the event viewer and let that run (not sure if PC needs to be 'awake' for that to keep recording).

 

Is there any place that keeps a history of variable changes, or takes a snapshot over a period of time?

 

I'd like to see when my variable is changing.

 

Thanks.

Hi Jamison_IO,

 

Unfortunately not. This said - and if you already have the network module - you can make your own:

With kind regards,

This could be done with the internal ISY logging facility via the notification technique also.

 

There is a thread on this back a few months ago with mwareman, myself, and others.

If someone read that part and had no idea where to start, where should he go to learn more?

I looked through this and tried to follow some links, but had no luck (i copy pasted the actual link target):

nevermind - i just popped it in the pattern of the current forum and it worked. that was confusing.

[Jamison_IO]

i am working on this and can't figure out how to monitor the variable to trigger the update. Is there a way to monitor the variable and write to file when it changes?

It must be a state variable, then it will trigger. Integer variables won't trigger automatically.

[Jamison_IO]

Thanks -I am using a state variable. I read the info, and am probably going about it all wrong.

 

I have the custom notification ready to go, I just do not know what to use in the program to trigger its use.

 

Edit - I am trying to use the internal logging, not the ISYlogger. I think that is where the disconnect is. My apologies, I should have been clearer.

[Jamison_IO]

Got it to work - it never says in the instructions what to use for the "Settings/Groups" in order to point it to the custom notification. That's where i was confused.

[larryllix]

I use one notification to write the column headers each month for a new file.

I use another notification to write the data to the same file each time a variable changes.

 

I use mwareman's script and some plug-ins to view the data on a chart.

 

I have discovered a lot of flaws in my HVAC system using these methods.

To put one more option on the table, is io_guy's ISY Logger. I think it does exactly what you want and can ship the results to syslog if you'd like. You id the variables you want to track by checking a box next to their name. You do need a separate windows or Raspberry Pi type system to run it on your network

 

 

Here is a sample of the csv output.. header row definition, followed by values:
