Has anyone else noticed this, I'm not sure it's a feature or a bug.

I have a bunch of Insteon switches and a few of the locations have 6 switches.  Almost all of them are the 2477D v.45

When I click multiple at the same time, close to the same time I see the LED indicate turning off, or on depending on if I'm turning it off or on.  Then the red LED on the switch will blink for a couple of second and go out.  Is this normal?

 

Here is the log from the ISY-

Most likely both are trying to send and receive messages from linked devices causing a collision somewhere so a responders message isn't getting back to them

A few things to consider as these can be a signs:

- Load: The bulb in use (CFL, LED, Florescent) may be absorbing / injecting noise on the line

- Hardware: One of the first of many signs of a failing switch are buzzing, flicker, or failure to turn on-off a load or react on a timely fashion.

- Programming: Another sign of a failing switch is it takes longer or simply won't accept new changes in the EEPROM.
