A Node-Red Node for collecting `day ahead` prices from Nord Pool Group.
npm install node-red-contrib-nordpool-api-plus
A Node-Red Node for collecting "day ahead" prices from Nord Pool Group. This plus node gives you more features and auto tested of codebase. To be more robust.
This is a fork of the original node-red-contrib-nordpool-api, but with source code on github to make pull request possible and issue handling....
..Later that year: the original code is now uploaded here
npm i node-red-contrib-nordpool-api-plus
This node uses the unofficial nordpool API found here.Usage
The area and currency can be changed by selecting from the drop down menu in the properties, or by inputting the setting via a
:
Examples:
Use a inject node to trigger a request to nordpool, to get prices for today.Its also possible to inject a
msg.date to get price from a specific date, or pricing for tomorrow. msg.date accepts any value parsable with javascript new date(). If you request tomorrows data before 14:42 there's a risk that data is not available yet and you will get the data from the current date. See API issue#1An 24 object long array is returned on success. The objects contains this properties:
timestamp, price, currency and area.
$3
Setup an inject node info a function node and then this node.
Added this to the function node to get date of today and add 1 to it.
`
msg.date = new Date()
msg.date = msg.date.setDate(msg.date.getDate() + 1)
return msg;
$3
In Node-RED editor, click menu at top right corner -> Import -> Examples -> node-red-contrib-nordpool-api-plus -> basic-dashboard.Use a function node to convert
to values readable for dashboard chart node like this:
The function node in this example contains:
`js
let msg1 = {}
for (var i = 0; i
topic:msg.payload[i].currency,
payload:msg.payload[i].price,
timestamp:msg.payload[i].timestamp,
}
node.send(msg1)
}
`This could be the displayed result in:
$3
Send returned data into a function node with this contentjs
for (let i of msg.payload) {
i.timestamp = new Date(i.timestamp).toLocaleTimeString('DE') // Use DE format of time
i.price = (i.price / 1000 * 1.25).toFixed(2) // Convert from MWh to kWh and add 20% tax
node.send({ payload: { price: i.price, timestamp: i.timestamp } })
}
``See issue#27 for different approach to get current price.
