“It works!! Apps unlock the key for usage off spot prices benefit. Charging, heating and many other things can be controlled when prices are low or lowest every day!”

How it works
Two ways to get started
What you need depends on what you want to control.
Plug it in yourself
For appliances with an ordinary plug: an oil radiator, a dehumidifier, a car charger on a wall socket.
- 1Buy a Shelly Plug smart plug.
- 2Install the free app and sign in with your Apple or Google account.
- 3Add the plug in the app and choose a rule, such as the cheapest hours of the day.
Have an electrician fit it
A water heater, electric heating or a heat pump is wired in, so the relay that controls it is fitted by a qualified electrician.
- 1Tell us what you want to control and where you live.
- 2An electrician fits a Shelly relay to the appliance's supply.
- 3You add the relay in the app and choose how the appliance runs.
- 4The app shows what you have saved.
You need a Shelly relay or plug (Gen2 or newer) and a market-price (spot) electricity contract. Not sure what suits you? Ask us
In the app
See what you save
Savings in euros for today, the week, 30 days or the year. Worked out from measured use, not estimates.
Runs when power is cheapest
Your devices run in the cheapest moments of the day, down to 15-minute periods. The price chart shows when control is on.
Heat when you need it
Simple rules for price and temperature: more heat on frosty days, less when it is mild. An affordable Shelly H&T works as the room sensor.
Across Europe
In use across Europe
Every day they run their devices in the cheapest moments of the day. The app works in 40 electricity markets in 26 countries.

Marco's everyday example
The water heater heats in the cheapest hours
A water heater on a timer heats at the same time every night, whatever the electricity costs. Marco, our electrician, makes it follow the price instead.
- 1An electrician connects a Shelly relay to the water heater's supply.
- 2In the app you choose: heat in the four cheapest hours of the day.
- 3Every day the app picks the hours from the new market prices, and the saving shows in euros.
“The water heater doesn't care what time it heats. Your electricity bill does.”

Features
Everything the app does
Savings you can follow
Your savings in euros today, over the last 7 and 30 days, this year and in total, against your region's typical fixed price or any contract you choose. Each device also shows what it saves today and tomorrow.
Spot, fixed or time-of-use
Spot, fixed-price or time-of-use contracts, day/night and seasonal rates included. Start from a ready-made contract for your region and edit it to match yours.
The price you actually pay
Network transfer, flat or by time of day, the supplier's margin, electricity tax and other surcharges are all in the price, with or without VAT. The automation and your savings run on what a kWh really costs you.
Cheapest hours
Run the water heater, heating or EV charging in the cheapest hours of the day, down to 15-minute periods.
Price limit
Let devices run only when electricity is cheaper than the limit you set.
Rules for price and temperature
Simple if – then – else rules on the electricity price, the outside temperature or your own temperature and humidity sensors.
Prices today and tomorrow
Each device shows the day's prices at your own contract price, and you can follow the spot prices of other markets as a chart or a table.
Energy and cost
Consumption in kWh and what it cost, from Shelly devices that measure energy, or estimated from your appliance's power.
Affordable sensors
A Shelly H&T (1st generation) works through your Shelly relay. No Shelly account or other app needed.
Programs
Several programs per device, so you can switch between operating modes as your needs change.
Manual control
Override the automation whenever you need to.
Multi-channel Shellys
Each channel of a 2-, 3- or 4-channel Shelly gets its own schedule, and the whole Shelly counts as one device on the free plan.
Remote access
Manage your devices and settings from anywhere.
Dashboard
All your devices, their programs and their status at a glance.
Hand over to the owner
An installer or a relative can set everything up and then transfer the devices and electricity contracts to the owner's own account, moving the devices to the home's Wi-Fi if needed.
Keeps running offline
The script on the Shelly is light. If the internet drops, devices carry on with their latest schedule.
Easy setup
Set up your Shelly devices directly in the app, with no other tools.
Try it first
Add a virtual Shelly and explore the app before you buy a device.
…and more.
Frequently asked
What do I need?
A Shelly relay or a Shelly Plug (Gen2 or newer), a market-price (spot) electricity contract, and the app on an iPhone or Android phone.
How much will I save?
It depends on what you control and how much the market price varies during the day, so we don't promise a figure in advance. The app works out your actual savings in euros by comparing what your electricity costs with a typical fixed-price contract in your region.
Do I need an electrician?
Not for appliances with a plug: you fit a Shelly Plug yourself. For a hard-wired water heater, electric heating or heat pump, an electrician fits the relay, and in Finland we can help you find one.
Which Shelly devices work?
Shelly second-generation and newer devices, for example the Plus 1PM, Plus 2PM, Pro 1PM, Pro 2PM, Pro 3EM and the Shelly Plug. You set them up directly in the app, with no other apps needed.
Does it keep working if the internet drops?
Yes. The Shelly carries on with its latest schedule and fetches new prices when the connection is back.
Can I help my parents save?
Yes. Set everything up for them in your own app, then transfer the devices and electricity contracts to their account with Transfer Ownership in the settings. From then on the devices are in their app.
Which countries does it work in?
40 electricity markets in 26 European countries, from Finland and the other Nordic countries to Central Europe, Spain and Italy.
Start for free
Download the app, add a Shelly and choose how it runs. You'll see the saving from the first day.

Are you an electrician?
Your customers ask how to get the most out of spot-price electricity. Fit a relay on your next water heater or heat pump job, and get installation requests from your area.
Control by price or sensor - See your savings right away
Savings in euros from day one, with no setup. Control devices by, for example, the market price, the outside temperature and the room temperature. 40 electricity markets across Europe.
A year of 15-minute electricity prices – what was it worth? Price control saves, quarter-hours add only a few euros
In October 2025 the spot price started changing every 15 minutes. We compared what quarter-hour prices meant over a year in 21 European price zones: heating a family of four's hot water at the cheapest times instead of on a night timer saved 38–316 €, but picking quarter-hours instead of whole hours added only 2–13 €.
