What is a Thermostatic Head?
A thermostatic head is a heating accessory that attaches to hot-water radiators to regulate their temperature. It is generally divided into two main categories: manual heads and smart heads.
- Manual Heads: these heads are adjusted directly on the radiator with a dial, allowing a simple but static temperature setting.
- Smart Heads: in contrast, smart thermostatic heads, such as the Eve Thermo, are connected devices that can be controlled remotely via a mobile app. They allow for finer, more flexible temperature management with features like scheduling (as if each radiator had its own thermostat), creating custom scenarios, and even synchronizing the heating system with other connected devices.
Smart thermostatic heads, integrated into a home automation system, can significantly improve a home's energy efficiency by automatically adjusting the temperature based on needs and avoiding unnecessary heating in unoccupied rooms.
In the case of the Eve Thermo, this intelligence is further enhanced by its integration with Apple HomeKit, which allows users to manage their heating with Siri and include the device in complex automations.
Key features of the Eve Thermo
Control via HomeKit and Siri
Eve Thermo is exclusively compatible with HomeKit, allowing control through Siri and advanced management via the Home and Eve apps.
The Eve app, with its intuitive interface and dark mode, makes accessing advanced settings such as scenes and automations easy, providing a smooth experience for users who want personalized heating automation.
Thread and Matter compatibility
With support for the Thread and Matter standards, Eve Thermo benefits from a stable connection and extended range.
This compatibility also makes interoperability with other Matter-enabled smart home devices easier, allowing users to build an intelligent, responsive network without needing a dedicated bridge.
Thread enhances responsiveness and communication reliability between devices, which is a valuable asset for advanced smart home systems.
Scheduling and scene management
Eve Thermo offers advanced scheduling capabilities, allowing users to program heating periods according to daily habits.
However, a HomePod (Mini) or Apple TV is required to leverage advanced automations (e.g., stopping heating when the home is empty), a limitation imposed by Apple for HomeKit.
Energy consumption optimization
By allowing temperature adjustment based on defined schedules, Eve Thermo reduces unnecessary heating, which lowers energy consumption and, theoretically, utility bills.
Additionally, an anti-limescale feature regularly activates the valve to prevent calcium deposits, ensuring radiator longevity and avoiding premature programmed obsolescence.
Installation and configuration
Installing the Eve Thermo is quick and does not require any specific tools.
After removing the old radiator head, simply screw the Eve Thermo into place and scan the QR code to integrate it into HomeKit.
An initial calibration automatically adjusts the valve's limits, simplifying temperature management.
Settings can then be refined in the Eve app, which provides a complete, smooth experience for Apple users.
Top 3 Advantages of the Eve Thermo
- HomeKit Integration and Control: Perfectly suited for the Apple ecosystem, the Eve Thermo integrates into a consistent smart home environment, allowing unified and simplified temperature control via Siri and HomeKit scenes.
- Design and Ergonomics: The minimalist design of the Eve Thermo, combined with its E-Ink display, ensures a clear reading of settings and a discreet integration into any interior.
- Privacy Respect: Unlike other solutions, the Eve app does not require location sharing, an appreciated feature for data privacy.
Top 3 Disadvantages of the Eve Thermo
- iOS and HomeKit Exclusivity: Eve Thermo is restricted to Apple’s ecosystem, a drawback for those with Android devices or smart home systems from Google or Amazon.
- Lack of Built-in Open Window Detection: Although the Eve Door & Window contact sensor (see below) can address this limitation, the absence of automatic open-window detection on the Eve Thermo itself can be a disadvantage compared to other models.
- Dependence on an Apple "Home Hub" for Automations: Without a HomePod or Apple TV, certain automation features are inaccessible, which may limit the experience for users without these Apple accessories.
Can you save by adding the Eve Door & Window contact sensor?
To optimize the Eve Thermo’s efficiency, the use of the Eve Door & Window contact sensor is highly recommended.
This window sensor detects when an opening occurs and can automatically stop heating in the corresponding room to avoid energy waste.
This solution is easy to configure in the HomeKit app and allows energy savings by limiting heating during regular room ventilation.
