Do not get confused. If you use Hubitat to control a Kasa Device, the status update is nearly immediate (< 1 second). If someone uses the physical switch paddle, the response will average 2.5 seconds (using user-selected 5 second polling). Some people use this as a three way so that when they turn on light A, light B turns on fairly quickly. It is functional enough for the preponderance of cases.
However, the motion detection on the switch is to control the light only - so, when the area MD switch turns on/off Hubitat can detect in 2.5 secs (average) and then through rule machine generate other actions. So it becomes a cost trade between 2 seconds and the added cost of the zigbee/zwave switch.
