+| sensorPollingInterval | Milliseconds between fetching sensor-values from the Hue bridge. A higher value means more delay for the sensor values, but a too low value can cause congestion on the bridge. Optional, the default value is 500. Default value will be considered if the value is lower than 50. Use 0 to disable the polling for sensors. |
