Graph or show log for derived value? Tracker doesn't seem to be the answer.

Hi,

Let's say you have a number of presence detectors in the house and want to log or graph when there was movement, on a coarse basis.

Eg. connect multiple detectors to the trigger of a 'switch off delay' block and set it's delay to 10 minutes or something. Have the output set a variable and show this variable in the UI.

This works, and yes, in the UI I can see the present value of the variable (whether there is someone in the house or not), but there seems to be no way to graph this value (it would just be on/off but you would have green bars on the graph showing when someone was home) and there seems to be no way to log this so that you can open the UI and see messages. Sure, you can send message to the default logger, but they are only available via FTP so not particularly user friendly.

What's the best way to get a log of 'Someone is home', 'No-one is home', 'Someone is home' messages?

I tried to use a 'tracker' but even when I tell it to record the last 100 events only see one. And even then it doesn't really seem correct :(

Cheers,

Robin

Try Virtual output control. Is allows statistics. I'm using it to log on and off states. Those can be displayed as bars on time axis with custom symbol.

Hi... this seems to work. Thanks :)

Ahhhh... I stumbled across 'Virtual State' recently. This appears to be just what I was looking for. Posting here in case anyone else is looking for this.

... although I have since discovered there's a nice 'side effect' the Virtual Output has that a Virtual State does not, which is that Virtual States do not appear in the periphery. This means if you use Virtual States and want to adjust the statistics periods (for example) on all your 'derived values' you have to go through each page looking for them. When using Virtual Outputs, as they appear in the periphery, it's easy to select all at once and modify various attributes.

Hi,

Today I have noticed that Memory Flags have statistics available.

Did I miss this before or was it a feature added after the initial post here? Seems that graphing a memory flag is a lot nicer than creating a virtual output to do the same thing.

Cheers,

What version of Lox Config are you on? Memory flags with statistics don't exist on v9.3.3.26.

I'm seeing stats on memory flags in 10.0.9.24.

I guess you have just confirmed - this is a new feature somewhere between the two.

Thanks,

Robin
