I'm updating the SensorDimmer->setPercentage() when a button is held, and currently a message is being sent to the network on every change.
I suggest enhancing the Child::sendValue some how so that if values change quicker than say 5 seconds (configurable) then these messages arn't sent until things have settled. Perhaps the SensorDimmer is a special case and sending messages can be prevented somewhere else, but though I'd mention it for feedback.
