This article will help you if you encounter any of the following issues:

- You have trouble finding your Thermo via Bluetooth
- The display of my Thermo doesn't turn on
- My Thermo can't connect to Wi-Fi
- The setup process fails

Note: Thermo is compatible with iOS 14+ and Android 8+. Before proceeding with troubleshooting, please make sure that your mobile device is compatible with your Thermo.




You have trouble finding your Thermo via Bluetooth

  • Make sure your Thermo is close enough to your mobile device (10 m/30 ft.).
  • Make sure your mobile device is BLE compatible.
  • Disable and re-enable Bluetooth on your mobile device, if necessary.
  • Go to the Settings of your mobile device, select Bluetooth and check if your Thermo appears in the list of devices. If so, select the small icon to the right of the Thermo and select the option to Forget or Unpair the device. 

Starting with Android 6 (Marshmallow), Android devices require location services to be enabled in order to detect and connect to Bluetooth devices via BLE (Bluetooth Low Energy). As such, you must enable location services on your Android device in order to install and sync your Thermo. For more information about Android’s permission requirements, see Google's Android 6.0 Changes document.



The display of my Thermo doesn't turn on

If the display of your Thermo doesn't turn on, or if it turns off right after displaying "SETUP", make sure the batteries work properly. You can try using new batteries to see if that's where the issue comes from.



My Thermo can't connect to Wi-Fi

If your Thermo can't connect to Wi-Fi, follow these steps:

  • If you get a DHCP or DNS error, reboot your router and start installing it again. If the problem persists, click here.
  • If you get an HTTP error, make sure your Wi-Fi network doesn't require you to enter a password on a webpage (for free or shared Wi-Fi networks) or that it's not behind a proxy.
  • If you get a Wi-Fi error 2, make sure you entered the right password.
  • If you get a Wi-Fi error 3, 4 or 5, try to get closer to your router and start the installation again.
    Note: Make sure you're not using a 5 GHz Wi-Fi network as it is not supported by the Thermo.
  • If you get a Wi-Fi error 6, reboot your router, make sure it authorizes new products to connect, and start installing it again.
  • If a MAC filter is set on your router, make sure you add the MAC address of your Thermo in your router's white list.

Due to local regulations on Wi-Fi devices, Bluetooth should be used to set up your Thermo in the following countries:

Andorra, Antartica, Bouvet Island, Cocos (Keeling) Islands, Cook Islands, Greenland, Heard Island and Mcdonald Islands, Iran, Republic of Korea, Marshall Islands, Palestine, State of Pitcairn, Saint Helena, Ascension and Tristan da Cunha, South Georgia and the South Sandwich Islands, Sudan, Svalbard and Jan Mayen, Syrian Arab Republic, Timor-Leste, Tokelau



The setup process fails

 If the setup process fails:

  • Make sure you have access to the internet on your mobile device.
  • Make sure that your mobile device stays on with the app kept open during the installation process.
  • Keep your Thermo close to your mobile device during the installation process.


I get a DNS or DHCP error during the setup

  1. Go to the Wi-Fi settings of your device.
  2. Check the details of your Wi-Fi network
    You will need to write down the following:
    - the first 3 numbers (or set of digits) of the 'IP address' field - in our example : 192.168.0
    - all of the numbers in the 'Subnet Mask' field - in our example :
    - all of the numbers in the 'Router' field - in our example :
  3. Go back to the app to start the installation process.
  4. Select Setup another network instead of Quick setup.
  5. Select your Wi-Fi network from the list of available networks.
  6. Type in your password and then tap Manual configuration.
    Fill in these fields with the information you copied from the Wi-Fi settings:
    - Paste the first 3 numbers of the IP address and add '250' as the last set of digits.
    - Paste all the numbers from the 'Subnet Mask' in the 'Netmask' field- Paste all the numbers from the 'Router' field.
