Wireless Smart Thermostat WT401
The demands placed on modern building technology are constantly increasing. Energy efficiency, increased comfort and intelligent automation are all becoming increasingly important factors, whether in residential buildings, offices, hotels or public facilities. Milesight’s new WT401 Wireless Smart Thermostat fits perfectly into this environment. This sophisticated control device combines state-of-the-art sensors, efficient technology and an extremely user-friendly interface.
Here at INOVIS, we are particularly pleased to add this new model to our range. We are based in Switzerland and have worked closely with Milesight for many years. You can now purchase the new device from our INOVIS web shop, where you will also find advice and support from our Swiss team.
Clear 2.7-inch E-Ink display for a brilliant overview
The first thing that catches the eye on the thermostat is its high-quality, 2.7-inch E Ink display. This technology is extremely energy-efficient and offers excellent visibility in a wide range of lighting conditions. Even in direct sunlight, the display remains crystal clear and easy to read.
E-Ink displays only consume energy when the screen content changes. This makes the technology ideal for long-term use, particularly when used with batteries or in energy-optimised installations.
Five large buttons – frustration-free operation
The thermostat’s design focuses on simplicity and practicality. Its five large, clearly structured buttons allow even inexperienced users to operate it intuitively right away.
The controls can also be adapted for different applications. For instance, certain functions can be locked in hotels, whereas individual settings are possible in office buildings. This combination of simplicity and flexibility is one of the great advantages of the new model.
All-in-one sensor technology: temperature, humidity and presence

From a technical perspective, the thermostat’s versatility lies in its sensor technology. The device measures three key parameters:
- Temperature
- Humidity
- Presence, via a PIR sensor.
This combination enables finely tuned climate control. The PIR sensor detects people in the room, ensuring that the temperature is only actively regulated when necessary. This prevents energy wastage while providing a pleasant room climate as soon as someone enters.
This results in considerable savings potential, particularly in commercial premises, schools and public spaces.
Three power supply options for maximum flexibility
Milesight has equipped the device with three possible power sources:
- Battery: ideal for simple, wireless installations.
- USB-C: provides a stable, continuous power supply.
- Powerbus: perfect for professional installations in modern buildings.

This means that the thermostat can be used in almost any environment, whether it’s a new build or a renovation project. This saves installation companies valuable time and coordination effort.
A practical sliding buckle design enables quick maintenance
The thermostat is also well designed from a mechanical point of view. The sliding buckle provides technicians with quick access to the interior for tasks such as changing the batteries or making configurations.
There are no fragile clips, so there is no risk of damaging the device. The robust mechanics are designed for durability. This greatly simplifies maintenance for operators of large properties.
The mounting is versatile. The back plate is decorative.

The thermostat can be mounted on a variety of surfaces. The decorative back plate ensures it integrates visually appealingly into any room. This is particularly important in hotels and modern offices, where design and functionality should be in harmony.
Anti-theft screw – greater security in everyday life
Thanks to the anti-theft screw, the thermostat is ideal for public or semi-public areas. Without tools, the device cannot be removed, which prevents tampering and theft.
This small detail demonstrates the practicality of Milesight’s design.
Automated climate strategy: presence and schedules
The combination of a PIR sensor and up to eight locally storable schedules turns the thermostat into a true automation tool.
When people are detected, the device dynamically adjusts the temperature. When no one is present, an energy-saving mode is activated. The schedules can be used to map precise working hours, school hours or hotel rhythms.
The result is smart, efficient, independent climate control.
Configuration is simple and can be carried out via NFC or fleet management
Another notable feature is the NFC configuration, which can be completed with a simple tap of the smartphone. This enables technicians to set up devices extremely quickly.
The Milesight Development Platform is ideal for large-scale installations. It enables entire fleets to be preconfigured, saving a considerable amount of time and reducing the error rate.
Part of a powerful product ecosystem
- WT101, which is designed for individual radiator
- WT201, a versatile solution
- WT30x, which is designed for fan coil systems
All models use LoRaWAN® connectivity. This enables intelligent, efficient and scalable climate control.
