Scenes, devices & the PLM 992 number?

[RichTJ99]

Hi,

 

I am trying to get a handle on if my system is beyond the 992 number of links & think I can delete a few scenes but am trying to understand what i need to accomplish.

 

I have a number of devices I am not really using such as the motion sensor which has a motion, dusk, and one other sensor, or a number of leak sensors that have leak on / off, heartbeat, etc.

 

Should I start getting rid of those?  

 

Would deleting the dusk/dawn part of the motion sensor save me a link?  

 

If i have a scene called all off & it has every device in it, is that a single link or multiple links?

 

I have an all off scene, and a downstairs scene - it has some overlap - is that multiple links?  

 

I am a bit confused & would like to get my count down.

 

On the main ISY page I have a total of 411 items - again this includes 8 button keypads, leak sensors that have 3 parts, motions that have 3 parts, etc.

 

Thanks!

A node (e.g., heartbeat) is not a link unless it has a responder. Each controller plus each responder, even if they're in the same scene. If you have one controller and 10 responders, then you have 10 links. If you don't mind the delay, use programs instead of an All Off scene. The devices will respond sequentially instead of concurrently, but program don't create links.

So is this accurate?

 

Total 50 devices

 

All Off:  

35 devices

5 controllers

 

Downstairs off:

15 devices

2 controllers

 

Upstairs off:

25 devices

1 controllers

 

Outside:

12 devices

4 controllers

 

Inside off (downstairs scene devices& upstairs scene devices)

37 devices

3 controllers

 

Does this mean I would be using:  192 links?

 

So if I use a program for all off, I would need to add each device into the program individually?  

 

I am a little confused.  I have a few programs that reference scenes because it is easier than adding devices individually.

 

Thanks,

Rich

Yes, just like a scene, each device has to be added to the program. It's a bit more tedious. Here's a calculator that may be of use to you.
