In times of rising energy costs, many households are looking for ways to reduce their heating costs. Smart radiator thermostats offer a promising solution here. They enable precise control of the room temperature and can therefore significantly reduce energy consumption. These devices are an attractive option, particularly for tenants who cannot make major structural changes.
The current test from IMTEST examined various models and shows that even inexpensive thermostats offer amazing performance. The test winner, the Bosch Radiator Thermostat II, impresses with its easy installation and extensive features. With features like offset, boost mode and geofencing, it offers a variety of control options. It is also compatible with common smart home systems such as Alexa, Google Assistant and Apple HomeKit.
Another highlight is the price-performance winner TP-Link Kasa KE100. This model is available from just 29 euros and offers easy setup and solid features. It works via WiFi and can be conveniently controlled via an app or voice assistant. However, the TP-Link Kasa Hub is required to use it, which must be purchased separately.
Other models such as the Homematic IP radiator thermostat Evo or the Osram LEDVANCE SMART+ also offer interesting functions and a good price-performance ratio. They score points with their ease of use, reliable window detection and the ability to integrate multiple users. Overall, the test shows that smart thermostats not only increase comfort, but can also make an important contribution to saving energy.
