Whether in your own home or rented through simple replacement – Instead of the conventional thermostat, you immediately benefit from all the advantages of a modern and intelligent heating system with the SIRO Smart Radiator Thermostat.

Easy conversion

The entire installation work to replace your existing thermostat with the SIRO Smart Radiator Thermostat consists only of unscrewing the old one and screwing on the new thermostat, which usually takes no more than a minute. The radiator does not need to be bled nor the water drained. In addition, adapter rings are included in the delivery, which make the SIRO radiator thermostat compatible with almost any valve commonly used in Germany.

Energy savings of up to 30%

Through several interlocking measures, you can save up to 30% on heating costs with the SIRO radiator thermostat. You not only reduce your own costs, but also make your contribution to environmental protection.

By analyzing the room properties and incorporating the weather forecast, energy-efficient heating is made possible. The intelligent time program and app control not only make the heating efficient, but also prevent unnecessary heating. With the time program, you will never forget to turn off the radiator when you are away.

In addition, the graphically displayed consumption statistics show you where you can still adjust your time program for efficient and conscious use.

App control with gateway

With the Smart Life App, you can control and program the SIRO Smart Bluetooth Radiator Thermostat SL02105B. It works exactly the same way on the Tuya App, if you already use the app.

In combination with a compatible Bluetooth gateway such as the SIRO SL02604B, you have all the options to implement an intelligent heating system with a time program, scene program, weather-dependent program, remote and voice control via Amazon Alexa and Google Home.

App control without gateway

Even without a gateway, the SIRO Smart Bluetooth Radiator Thermostat SL02105B can be controlled via the Smart Life App. The Bluetooth system installed in the device also enables a direct connection to your phone and makes the application possible without a gateway.

The exception to this, however, is the option of remote control and voice control; these functions are not possible without a gateway.
