Multiple MS II in one room

[lgilsenberg]

Thank to larryllix and oberkc I’ve gotten ms II to work by linking to a scene and getting different lighting levels by adjusting the scenes, I was thinking of taking it one more step and using multiple ms ii in one room to ensure the lights stay on when there is an occupant and triggers on quickly regardless of the entryway.  
 

a couple of questions:

1- are there any subtleties that I should be aware of with having multiple ms ii in a single room?

2-  are there advantages of moving to v5.x for this scenario?

How are your MS powered?  If any of them are battery powered (i.e. not USB powered) then v5 actually introduces a problem.  It seems that in V5, when you adjust the setting of a responder in the scene, the system writes to both the responder and the controller, even though there shouldn't be anything to write to the controller.  If the controller is battery operated then it's probably asleep when the system tries to adjust the scene, and the write is queued.  People have reported their ISY becoming slow and/or unresponsive after enough writes to their MS have been queued, though UD says that the system only saves the last write in a queue.  The workaround for this problem is to disable writes to battery operated devices, but this can only be done if you have the Pro version.  And even if you can disable writes to battery operated devices, you'll eventually have to turn writes back on when you actually want to update a battery operated device's settings, and people report that the queued writes from earlier can then cause problems.  Here is a link to a discussion if you're interested:
