Frequently Asked Questions - Wireless Temperature Sensor TADO

How do I pair the Wireless Temperature Sensor with the Tado Smart Thermostat?

Follow the instructions in the Tado app. Go to 'Add Device', select 'Wireless Temperature Sensor', and press the pairing button on the sensor (or insert batteries) until the LED flashes. The app will guide you through the rest.

Can I use the sensor outdoors?

No, the sensor is designed for indoor use only. It has an IP20 rating, meaning it is not water-resistant. Exposure to moisture or extreme temperatures may damage it.

What type of batteries does the sensor use and how long do they last?

The sensor uses two AA batteries (alkaline recommended). Battery life is typically up to 2 years depending on usage and environmental conditions.

How can I check the battery level?

Open the Tado app and select the sensor. The battery level is shown as a percentage. A low battery warning will also appear when replacement is needed.

Why is my sensor not reporting temperature?

Ensure the sensor is within range (up to 30 m indoors) and that there is no obstruction. Check that batteries are installed correctly and not depleted. If the issue persists, remove and reinsert batteries to reset the device.

Can I mount the sensor on a wall?

Yes, the sensor can be wall-mounted using the included bracket and screws. Alternatively, it can be placed on a flat surface. Avoid placing it near heat sources, direct sunlight, or drafts.

How often should I clean the sensor?

Clean the sensor occasionally with a soft, dry cloth to remove dust. Do not use water, solvents, or abrasive cleaners. Ensure the ventilation openings are not blocked.

Is the sensor compatible with third-party smart home systems?

The sensor works exclusively with Tado's ecosystem (Tado Smart Thermostat and the Tado app). It is not directly compatible with other smart home hubs without additional integration via Tado's API.

Does the sensor also measure humidity?

Yes, the Wireless Temperature Sensor includes a humidity sensor. Humidity data is displayed in the Tado app alongside temperature readings.

What do I do if the sensor disconnects from the system?

First, check that the sensor is powered and within range. Restart the Tado Smart Thermostat by cycling power. If the issue continues, delete the sensor from the app and re-pair it following the initial setup steps.

3. Replace the room thermostat

Caution! Turn OFF the power before wiring!

If there is a wired room thermostat installed in the zone that is intended to be controlled by the Wireless Receiver, please decommission it by bridging the control wires and insulating the other wires with the included 2-terminal connector blocks as shown in the images.

Once tado° is installed, the Wireless Receiver will be the only device that controls the heating system.
