Nodes

LoRa Nodes are used to receive data from the LoRa Sensors (Droplets and MicroEdges) that have been configured in Rubix Platform (see Preparartion article links below). 

LoRa-Droplet

The LoRa-Droplet node functions as a method to import points from a Droplet device (configured in Rubix Platform).  This allows for the use of the sensor measurements to be utilised within the Rubix Wires programming.  The LoRa-Droplet node allows advanced flows to be created based on the elements and properties of a Droplet device, such as temperature, humidity, light levels, and other available Droplet properties.

Outputs

1. JSON - JSON is the summation of all data available from the device in a single JSON string.  This includes all data points, not just the data points available on the node outputs.  Most often used for debugging purposes.
   
2. ID - ID is the Sensor ID of the LoRa Droplet, this will be unique to each LoRa sensor.
   
3. Voltage - Voltage is the voltage of the batteries in the device.  
   
4. RSSI -  Received Signal Strength Indicator (RSSI) is a measurement of the power present in a received radio signal.  This is how good the quality of the wireless LoRa connection is.  A negative number closer to Zero is better.
   
5. LowBatteryAlm - Low battery alarm is a boolean and is triggered to true whenever the voltage (of the batteries of the droplet) drop below the pre-set limit.
   
6. Watchdog - Watchdog is a boolean that triggers to true when data has not been received from the LoRa Droplet within the configured interval.
   
7. Temperature - Temperature is the temperature measurement last pushed from the LoRa Droplet.
   
8. Humidity - Humidity is the humidity measurement last pushed from the LoRa Droplet.
9. Lux - Lux is the light level (unit of luminance, equal to one lumen per square metre) last pushed from the LoRa Droplet.
10. Pressure - No Longer Supported.
    
11. Movement - Movement is a boolean and is true/1 if movement was detecting when the LoRa Droplet last pushed data.

Settings

1. Name - The desired name of the node.
   
2. Enable - Node will not function if Enable is not switched on.  Can be used to disable the node functions.
   
3. Selected Sensor - (Read-Only) This is the currently selected sensor.
   
4. Topic Type -This is how the sensor is referenced within the Rubix Platform/Wires environment.  This can either be by the Sensor ID, or by the UUID of the sensor (in Rubix Platform).
   
5. Low Battery Warning Voltage - This is the voltage level of the low battery warning. Anything less than this set level will trigger low voltage warning.
   
6. Watchdog
   
1. Time - The unit of time for Watchdog (No message warning) delay.
2. Watchdog (No message warning) delay - The duration of time before the watchdog triggers if no data is received/pushed from the sensor.
   

Operation

When Rubix Platform receives a data push from a LoRa Droplet sensor, the data is sent to the corresponding LoRa-Droplet node so that the measurements can be used for logical programming within Rubix Wires. 

Troubleshooting

1. If the dropdown list of LoRa Droplet Sensors is empty (or not up-to-date) please click Settings > Save, then re-open the Settings for the LoRa Droplet Node. 
   
2. In order for the LoRa nodes to receive data from the LoRa App, the LORA_RAW config file must have the correct MQTT details.  Contact Nube-iO Support for assistance if you are not receiving data to the LoRa nodes.
   

LoRa-MicroEdge

The LoRa-MicroEdge node functions as a method to import points from a MicroEdge device. This allows for the use of the device properties to be translated and utilised within the Rubix Wires environment for processes. The LoRa-MicroEdge node allows advanced flows to be created based on the elements and properties of a MicroEdge device, such as pulse counts, and analogue data.

Outputs

1. JSON - JSON is the summation of all data available from the device in a single JSON string.  This includes all data points, not just the data points available on the node outputs.  Most often used for debugging purposes.
2. ID -ID is the Sensor ID of the LoRa MicroEdge, this will be unique to each LoRa sensor.
3. Voltage - Voltage is the voltage of the batteries in the device.  
4. RSSI -  Received Signal Strength Indicator (RSSI) is a measurement of the power present in a received radio signal.  This is how good the quality of the wireless LoRa connection is.  A negative number closer to Zero is better.
5. LowBatteryAlm - Low battery alarm is a boolean and is triggered to true whenever the voltage (of the batteries of the droplet) drop below the pre-set limit.
6. Watchdog - Watchdog is a boolean that triggers to true when data has not been received from the LoRa Droplet within the configured interval.
7. Pulses - Pulses is the measurement of pulses that the device has received at the pulse input on the MicroEdge sensor.
   
8. A1/A2/A3 - A1/A2/A3 respectively is the measurements taken from each analogue input point on the MicroEdge sensor.

Settings

1. Name - The desired name of the node.
   
2. Enable - Node will not function if Enable is not switched on.  Can be used to disable the node functions.
3. Selected Sensor - (Read-Only) This is the currently selected sensor.
   
4. Topic Type -This is how the sensor is referenced within the Rubix Platform/Wires environment.  This can either be by the Sensor ID, or by the UUID of the sensor (in Rubix Platform).
   
5. Low Battery Warning Voltage - This is the voltage level of the low battery warning. Anything less than this set level will trigger low voltage warning.
   
6. Watchdog
   
1. Time - The unit of time for Watchdog (No message warning) delay.
2. Watchdog (No message warning) delay - The duration of time before the watchdog triggers if no data is received/pushed from the sensor.
