node-red-contrib-virtualmeter

Node-RED based Virtual Power Meter Node to be used within Corrently Ecosystem (German Electricity Grid). Prepared for load (consumption) prediction and PV generation forecast. Uses InfluxDB and GreenPowerIndex under the hood.

Installation

cd ~/.node-red
npm install --save node-red-contrib-virtualmeter
node-red-restart

Use Cases

• You have only a power value and need a energy meter (reading)
• You have a meter reading and you need the actual power
• You have a consumption over time and need a meter (total energy)
• You have one of those items and need CO2 footprint

Usage

Add virtualmeter node to your node-red flow and connect data source to input. Use input values as of following list to have a managed (virtual)meter for electricity.

You might have a look at the sample flows to get an overview of existing

Input Values

If msg.payload is number, than this number will be interpreted as Watt hours (Wh) to be added to meter reading.

If msg.payload.energy exists this will be used as new meter reading in Watt hours (Wh)

If msg.payload.power exists this will be used as average power (Watt) since last message

If msg.payload.power_mw exists this will be used as average power (Milli Watt) since last message

Example

Use with TP Link Kasa HS 110 Smart plug

Node: LoadPrediction

Allows to get a load prediction for energy consumers. This is a quite simple forecast implemenetation that mainly focuses on data stored into an influxDB using a VirtualMeter Node.
