INTRODUCTION COMET WIFI

Thank you for choosing a product from Eurotronic Technology GmbH. This device can easily adjust the temperature in your rooms according to your wishes and helps you to effectively reduce your heating costs.
Development and production are 100% “Made in Germany“, which guarantees the highest quality and technology. These operating instructions will help you to put your device into operation quickly and easily.

THIS IS COMET WIFI

Comet WiFi is an energy-saving controller for radiators equipped with the WiFi radio standard, with modern and simple operation. It automatically regulates your room temperature according to your specifications and is configurable, directly on the controller or conveniently via smartphone via your WiFi network.

CONTROL AND DISPLAY ELEMENTS

Button in the battery compartment for performing the factory reset or activating the pairing mode:

NOTE: The first model series has a lower reset button that is operated with the supplied tool.

INSTALLATION AND START-UP

The following explanations describe the procedure using an Android app (app version: 1.2) and may differ slightly for Apple. In addition, the screenshots shown may differ from newer app versions.

DOWNLOAD APP

Download the “WiFi Smart Living“ app from the Google Play Store or Apple App Store.

CREATE USER ACCOUNT

Create a user account. Enter your email and choose a password.
Note: Make sure you enter a valid email address. The app does not check the validity of the email.
Accept our terms and conditions and privacy policy.
Click on the “Create new account“ button.
You will now receive an e-mail Pin for verification. Check also your spam folder.
Enter the pin you received by email, in the field.
Then click on the “Login“ button

The WiFi network to which your smartphone is connected is automatically displayed in this field. If you want to integrate your Comet WiFi into a different WiFi network than the one shown to you, temporarily connect to a different WiFi network in your smartphone‘s WiFi settings and return to the app. The correct WiFi network is then displayed under “My WiFi network“.

NOTICE:
So that your WiFi network in the “My WiFi network“ field automatically can be displayed, the following factors must be present:

Your WiFi network must operate on 2.4 GHz since Comet WiFi can only be integrated into a 2.4 GHz WiFi network. This can be viewed in the settings of your WLAN router and changed if necessary.
Your smartphone‘s location approval must be enabled.
The WiFi Smart Living app needs permission to access your location while using the app. If you have denied location access in the app, go to your smartphone settings and adjust the permission. (Android: In the “Apps“ section, you can grant the “WiFi Smart Living“ app location access again while using the app.)

Enter the password of your WiFi network correctly. This is important because the app cannot check your home network‘s WiFi password. You will continue to be guided through the setup wizard despite the incorrect password.
After entering the WiFi password, click “Next“.
NOTICE:
Comet WiFi can only be integrated into 2.4 GHz WiFi networks. If the router transmits exclusively on 5GHz, device conrol is not possible. The router must be set to 2.4GHz or 2.4GHz/5GHz mixed networks.

INSERT BATTERIES

SETUP THERMOSTAT

Go to your smartphone‘s WiFi settings and connect to your thermostat there. Depending on the software version, your thermostat is displayed with the WiFi radio name in the WiFi settings as “Comet WiFi“ or “Eurotronic“. If you have purchased a device with older software (radio name: Eurotronic), a software update will be carried out directly during setup.
