Smart Plug with Nord Pool Integration - Save €175 a Year
Nord Pool electricity prices can range from around 3 cents to €1 per kWh within the same day. That is more than a 30× difference.
If you have a fixed electricity tariff, or a spot tariff but don’t choose the cheaper hours, the electricity used by your boiler costs around €250 per year on average. People usually use hot water at times when electricity prices are higher.
If you heat the water only during the cheaper hours, the yearly cost is around €75. That’s a noticeable difference - about €175 per year.
The question isn't whether to switch to a spot-price plan anymore. It's how to avoid checking the price chart every half hour.
A smart plug with built-in Nord Pool integration does that for you.
How does it work?
- Plug it into a standard 220V outlet and connect your appliance.
- In the app, choose "5 cheapest hours" or set a cap like "under 5 cents per kWh"
- The plug reads tomorrow's Nord Pool prices and switches your appliance on during those hours
- Every day, the app calculates: “Saved €0.42 compared to the average daily price.”
That's it. Setup takes 3 minutes. Nothing else to do after that.
How much could I save on one appliance?
Calculations based on real Nord Pool prices for H1 2026.
*These figures assume a standard 80L boiler, 2 kW power, heating to 60°C, and roughly 4 kWh per heating cycle.
4 kWh × 365 days × €0.17/kWh = €250 a year - approximate cost of running the boiler under these conditions.
4 kWh × 365 days × €0.04/kWh = €73 a year - approximate cost of running the same boiler only during hours when the price stays under 5 cents.
In that case, the plug pays for itself in 2 month.
*These amounts depend on the volume and power of your boiler.
**The calculations are based on a scenario where the boiler heats a full tank of water per day — the hot water tank is emptied and then refilled with cold water.
Brand Comparison

Shelly is cheaper upfront, but automation based on Nord Pool spot prices usually requires additional setup: Pörssäri, Home Assistant, or another third-party solution.
GPO costs €30 and already includes Nord Pool automation in the app, with no subscription required.
Why does GPO work without third-party services?
Some smart plugs need a third-party solution for Nord Pool price automation. That means a separate subscription: Pörssäri, Spot-hinta.fi, IFTTT or another technical solution.
GPO reads the Nord Pool API directly through the GPO Home app. The integration is built in at the factory. No subscriptions, no IFTTT, no Home Assistant - just the plug and the app.

| Appliance | Without plug | With GPO smartplug | Savings |
| 2 kW boiler | €250/year | €75/year | €175 |
| 1.5 kW heater | €210/year | €130/year | €80 |
| Dishwasher | €130/year | €65/year | €65 |
| Total | €620 | €270 | €350 |
Investment: 3 smart plugs × €30 = €90. Pays for itself in 3–4 months, or within one heating season.
