# 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
```bash
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.
