Clearly if I poll each of my 9 devices with the flex-getter like in the picture (with 1 second inject interval). The answers will start to stutter and messages come in very randomly. It works correctly but its not the action I want. I would like to have even flow of messages from the devices.

Your best bet is to wire in series.
