smithtek-node-red-meter v0.1.0

smithtek-node-red-meter

The meter node multi function node for: A: Recording run hours. this could be a machine, device, pump,motor. B: Totalizer that can convert pulses into totals.This could be a water flow meter, energy meter to name a few. The package contains 3 modules . Metering Multiply Reset

Installation

Using node red palette manager search for "Smithtek-node-red-meter" Or CMD npm install smithtek-node-red-meter

Configuration

Metering Node

• Data Store Save to: The data can be stored to persistent context. The data will remain after restarts for the period required.
• Meter Type: run Hours totalizer

Signal start You can select string,bool,number to trigger the recorder When in Run Hour mode the value increments in seconds. Additional nodes will be required to convert this to minutes or hours. when in totalizer mode the neter will multiply the incoming value by the setpoint value adjustable in the config properties.

Signal stop You can select string,bool,number stop the recorder

Configuration

Reset Node connect the reset node to the metering node send any message to the reset node. This will clear the recorded values.

Configuration

Multiplier Node When the metering node is configured to be a Totalizer connect the multiplier node to the metering node Send a message payload with a number. this will overide the multiplier property setting. Example : Your flow meter pulses once every 10 litres. you set the multiplier value to 10.

Note

The record value can be save even node-red is restarted

Input

• Record time:
  • reset signal: to reset global/flow variable to 0
  • start signal: start record time
  • stop signal: stop record time
• Record pulse:
  • reset signal: to reset global/flow variable to 0
  • set multiplier: to set multiplier value
  • input pulse aka msg from physical hardware or upstream nodes.

Outputs

• Record time: When the node is recording time, it will send the output value every second.
• Record pulse: The Input message will throughput to the output.
