Easy conversion

Replacing your existing thermostat with the SIRO Smart Radiator Thermostat involves simply unscrewing the old one and screwing on the new one, which usually takes less than a minute. There's no need to bleed the radiator or drain the water. Adapter rings are also included, making the SIRO Radiator Thermostat compatible with almost every 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. Not only will you reduce your heating costs, but you'll also be contributing to protecting our environment.

By analyzing room characteristics and incorporating the weather forecast, energy-efficient heating is achieved. Intelligent time programs and app control not only make the heating efficient but also prevent unnecessary heating. A time program will never forget to turn off the system when you're away.

And the graphical consumption statistics show you where you can still adjust your schedules.

Easy control via app

In conjunction with a compatible Zigbee gateway such as the SIROSL02804ZorBluetooth and Zigbee Multimode USB Gateway SL06004EYou can control and program the SIRO Smart Radiator Thermostat SL02205Z with the Smart Life app. It works the same way with the Tuya app if you already have it installed.

However, the use of the Zigbee gateway is necessary here - but this gives you all the options to implement an intelligent heating system with a time program, scene program, weather-dependent program, remote and voice control with Amazon Alexa and Google Home.

Frequently Asked Questions about the SIRO Smart ZigBee Thermostat:

Do I need a ZigBee gateway to use the SIRO Smart Thermostat?

Yes, you need a ZigBee gateway for the smart home functions. The device is compatible with common gateways such as Philips Hue, Amazon Echo Plus, or a separate Tuya ZigBee hub. Without a gateway, you can only operate the thermostat locally via the display.

How do I connect the thermostat to the Smart Life App?

Open the Smart Life App and tap the plus icon. Select "Thermostat" from the device list and follow the instructions. The device must be in pairing mode (press the reset button for 3 seconds). The connection is made via your ZigBee gateway, not directly via Wi-Fi.

Which voice assistants are compatible with the SIRO Smart?

The thermostat works with Amazon Alexa and Google Assistant. After setup in the Smart Life App, you can set and query the temperature by voice command. Integration is done via the respective smart home skills of the Tuya platform.

How accurately does the integrated temperature sensor measure?

The integrated temperature sensor measures room temperature with an accuracy of ±0.5 °C. It is specifically designed for use on radiators and ensures reliable temperature control in the room. Fine adjustment of the readings can be made via the app if necessary.

Can I create individual heating profiles for each day of the week?

Yes, via the Smart Life App, you can create detailed schedules with up to 6 switching times per day. Each day of the week can be programmed individually. In addition, presets such as "Eco", "Comfort", and "Away" are available for quick adjustment.

What power supply does the SIRO Smart ZigBee Thermostat require?

The device is mounted directly on the radiator and powered by 2 × 1.5 V AA batteries.

Does the thermostat work without an internet connection?

Local control via the touch display always works, even without internet. For app control from on the go and automations, you need an active internet connection. Stored schedules are also executed offline as long as the gateway is powered.
