For information on how to configure parameters for your devices check out Adding Configuration Parameters.

Setting parameters on NERO-MULTI

NERO-MULTI creates 5 elements in the NERO OS interface. When you are changing parameters you must always use the main element which is the motion sensor, highlighted below.

If you NERO-MULTI is powered using batteries you will either need to wait for the next wake up event (this may take up to an hour or more) or you will need to wake the sensor. If you want to wake the sensor, set your configuration parameters and then press the button on the back of the sensor. It will wake up and check in with the gateway, receiving the new settings.

Configuration parameters

Parameter no. 3 - Motion timeout

When the Motion Sensor detects movement, the NERO-MULTI’s status will appear as “tripped” in the NERO OS. After 4 minutes (by default), if the Motion Sensor is not triggered again, the NERO-MULTI will appear as “not tripped”. However, if the Motion Sensor is triggered again within 4 minutes, the NERO-MULTI will reset the timeout and start counting again.

Available settings (data type: 2 Byte DEC):

• [DEFAULT] 240 - 4 minutes
• 10-255 - Timeout value in seconds
• 256-3600 - Value divided by 60 then rounded up to give minutes, e.g., 3600 would set the timeout to 60 minutes

Parameter no. 4 - Motion sensitivity

You can change the sensitivity of the motion sensor to reduce the detection range and false alarms. When changing this setting we recommend you change it only one step at a time to ensure you don't set it too high or too low.

Available settings (data type: 1 Byte DEC):

• [DEFAULT] 5 - maximum sensitivity
• 0-5 - Sensitivity of the sensor with 0 being the minimum sensitivity and 5 being maximum

Parameter no. 101 - Which reports are sent to the gateway

You can configure which reports are sent to the gateway to reduce the amount of traffic on your network, for example, sending battery reports when USB powered is a waste of a message.

Changing this value will not remove the disabled sensors from the NERO OS interface, it will simply stop the messages being sent and reduce network traffic.

Available settings (data type: 4 Byte Dec):

• [DEFAULT] 241 - Report all items
• 240 - Report Luminance, Humidity, Temperature, and Ultraviolet
• 225 - Report Luminance, Humidity, Temperature, and Battery
• 224 - Report Luminance, Humidity, and Temperature
• 97 - Report Humidity, Temperature, and Battery
• 96 - Report Humidity and Temperature

Parameter no. 111 - Reporting interval

The delay between sending environment sensor reports (temperature, humidity, UV, and illumination).

Setting this parameter too low can cause your wireless mesh to become busy and cause commands to not be sent or received correctly. We recommend not setting this parameter lower than 60.

Available settings (data type: 4 Byte DEC):

• [DEFAULT] 3600 - 1 hour
• 5-65535 - Interval in seconds between reports when USB powered
  • When powered by batteries the value will be rounded up to the nearest hour (e.g., 5-3600 will update hourly, 3601-7199 will update every 2 hours)

Recommended parameters

For optimal performance of your Nero Multi sensor there are some recommended parameters that adjust how often the device sends messages to the gateway.

Powered with USB

When powered by USB, you can set your Nero Multi to report far more regularly without concern about it depleting the battery. You also don't need to know the battery level (it will always be 100!) so you can remove this report type.

Powered with CR123A batteries

When powered by batteries, you want to limit how often the device is waking up the radio as this depletes the battery rapidly. We recommend not sending values more often than hourly.
