Fourdeg WiFi Smart Radiator Thermostat
Room-level heating control for individual homes and small buildings connected to district heating. Connects directly to WiFi — no hub needed. AI learning optimizes your heating automatically.
Intelligent Heating for Individual Homes
The Fourdeg WiFi Smart Radiator Thermostat brings intelligent, learning heating control to single-family homes, townhouses, and small residential buildings connected to district heating systems.
Unlike traditional thermostatic radiator valves, the Fourdeg WiFi thermostat connects to the cloud and uses weather forecasts, learning algorithms, and room-level data to optimize heating automatically — without you having to think about it.
Each room follows its own comfort target. Mild weather is handled before overheating starts. Colder periods are prepared for without raising the whole home unnecessarily. The system keeps improving as it learns your home.

What Makes the WiFi Thermostat Special
Direct WiFi — No Hub Needed
Connects directly to your home WiFi network without any additional gateway or bridge. Simple setup through the Fourdeg app takes just minutes.
Room-Level Learning Control
Set individual temperature targets for each room. The AI learns how each room heats and cools under different conditions and optimizes automatically.
Built for District-Heated Homes
Designed specifically for water-circulating radiators in district-heated homes. Understands the unique dynamics of district heating supply — not just generic smart home control.
Getting Started
Easy Installation, Immediate Results
Install on Your Radiators
Mount the WiFi thermostat on each water-circulating radiator. No tools or wiring required — it replaces your existing thermostatic valve head using standard fittings.
Connect to WiFi
Use the Fourdeg app to connect your thermostats directly to your home WiFi. No hub or gateway needed — setup takes just a few minutes per device.
Set Your Preferences
Choose your desired temperatures for each room. The AI immediately starts learning your building's thermal behavior and begins optimizing from the first day.
Enjoy Smart, Learning Heating
The system continuously improves as it gathers more data about your home. Weather forecasts, room usage, and building characteristics all feed into the optimization — saving energy while keeping you comfortable.
Use Cases
Designed for District-Heated Homes
The Fourdeg WiFi thermostat is suited to single-family houses, row houses, and small buildings that use water-circulating radiators connected to district heating.
Homeowners use the system to reduce overheating in rooms with strong sunlight, keep bedrooms cooler at night, and maintain warmer settings in spaces used during the day. The cloud service gives remote access without a separate building automation system.
For small landlords and housing associations, the same approach brings consistent comfort and clearer energy data to multiple homes while avoiding the complexity of a large commercial installation.
Frequently Asked Questions
Everything you need to know about WiFi radiator thermostats and smart heating for district-heated homes.
What is a WiFi radiator thermostat?
A WiFi radiator thermostat is a smart valve head that replaces the manual thermostatic radiator valve (TRV) on a water-circulating radiator. It connects to your home WiFi so you can control heating remotely and lets AI optimize heating automatically. The Fourdeg WiFi thermostat uses machine learning and weather forecasting to predict heating needs — not just react to temperature changes after they happen.
How does a learning radiator thermostat work in a district-heated home?
A learning radiator thermostat builds a model of how each room in your home heats and cools over time. It tracks how the room responds to outdoor temperature, sunlight, and occupancy patterns. Over the first weeks, Fourdeg's thermostat learns your home's specific thermal characteristics and starts anticipating when to open or close the radiator valve — warming rooms before you need them warm, and reducing heat before overheating occurs.
Does the Fourdeg WiFi thermostat need a separate hub or gateway?
No. The Fourdeg WiFi radiator thermostat connects directly to your existing home WiFi network. There is no separate hub, bridge, or gateway required. You set it up through the Fourdeg app, which connects it to the cloud service where the AI optimization runs.
Is the WiFi radiator thermostat easy to install?
Yes. The Fourdeg WiFi thermostat replaces your existing thermostatic radiator valve head with no tools and no wiring. It uses standard connection fittings that fit most European radiators. Installation takes about five minutes per radiator, and the app walks you through the process.
How much can a smart WiFi radiator thermostat save on heating costs?
Homeowners using Fourdeg's WiFi radiator thermostats typically save 20–35% on district heating costs. The savings come from eliminating overheating in individual rooms, reducing heating during unoccupied periods, and optimizing the heating curve based on actual outdoor conditions. Homes with south-facing glazing or large temperature variation between rooms tend to see the biggest savings.
