Temperature Sensor RF for Zigbee Thermostat

Remote sensor and control unit for thermostats

The external temperature sensor and control unit enables convenient management of up to 8 Siro Zigbee thermostats simultaneously. The radio connection allows multiple radiators to be controlled efficiently without direct app connectivity.

Precise real-time temperature measurement

The integrated temperature sensor reliably measures room temperature in real-time. This enables particularly accurate heating control, leading to a consistent room climate and efficient energy use.

Easy setup and flexible use

The connection between the control unit and the thermostat is straightforward via radio communication. This means the unit can be set up quickly and provides a central solution for controlling multiple radiators in your home.

Frequently Asked Questions about the SIRO RF Temperature Sensor for Zigbee Thermostat:

How do I connect the SIRO temperature sensor to my Zigbee thermostat?

Open the Smart Life app and select "Add Device". Activate pairing mode on the temperature sensor by pressing the reset button three times. The sensor will automatically connect to the thermostat via your Zigbee gateway and appear in the app for further configuration.

What is the range of the Zigbee temperature sensor in my home?

Under optimal conditions, the SIRO temperature sensor has a range of up to 30 meters. Thanks to the Zigbee 3.0 mesh network, other Zigbee devices can act as repeaters and significantly extend the range. Thick walls or metal objects can impair the connection.

How accurately does the SIRO sensor measure room temperature?

The temperature sensor operates with a measuring accuracy of ±0.5°C and updates values every 30 seconds. This precise measurement allows for efficient heating control and prevents temperature fluctuations. Calibration is done at the factory and remains permanently stable.

Can I use multiple temperature sensors in one room?

Yes, you can set up multiple SIRO sensors per room. In the Smart Life app, you can define different measurement points and calculate average values. This is particularly useful in large rooms or with unfavorable radiator positions for an even temperature distribution.

How long do the batteries in the temperature sensor last?

With two AA batteries, the sensor operates for approximately 12-18 months in continuous operation. The Smart Life app displays the battery level and sends a timely notification before a battery change is needed. Use high-quality alkaline batteries for maximum battery life.

Does the sensor also work with other smart home systems?

The SIRO temperature sensor is compatible with all Zigbee 3.0 gateways. In addition to the Smart Life app, it works with systems like Philips Hue, Amazon Echo Plus, or Samsung SmartThings. Integration is done via the respective manufacturer's app as a generic Zigbee device.

Where should I best place the temperature sensor?

Mount the sensor at about 1.5 meters height on an interior wall, away from radiators, windows, and direct sunlight. Avoid drafts and heat sources like televisions or lamps. The included stand also allows for flexible placement on furniture.
