One negative difference I noticed in the 994 programming vs. 26:  in the 26, when you remove a device, if you look at a program where it was used, the name is replaced by <unspecified> or something like that.  In the 994, the name is still in the program, leading one to think the device is still there.  

Is that normal behavior?

Not normal.  Did you click on Save Changes?  This is from 4.4.2.

 

AAAA0 - [iD 002E][Parent 0001]

 

If

        From     3:00:00PM

        To      11:00:00PM (same day)

    And Control <Not Specified> is switched On

 

Then

        Set 'ApplianceLinc' On

        Wait  10 seconds

        Set 'ApplianceLinc' Off

        Wait  10 seconds

        Run Program 'AAAA0' (If)

 

Else

        Set 'SwitchLinc Dimmer DB' 3%

No I didn't make any program changes.  Just deleted the device and when I looked at a program it was used in, the name was still there.  Strange.  I don't have anything to delete right now, so I'm not going to try and duplicate it.  I wonder if it could have something to do with the age of the modules and the old firmware in them.  Doesn't seem like it should as it seems like it is strictly an ISY OS issue, but I have had a number of random issues with some of these really old modules, I'm replacing them with new ones.

The Program was changed because the device being referenced is no longer there.  The Program maintaining name of device is useful when a device is Deleted and immediately added back.  This sequence is done at times when device is misbehaving and may be resolved by a delete/add sequence that does not require having to update the affected Programs.

Ok, interesting, I'll have to make note of that for future.  Acts a little differently.  Thanks!
