1. The router blocked the device from accessing the Internet. Change the network settings on the router.
2. The provider has blocked access to the servers. Set up a VPN on your router.

UDP access blocked. Change the network settings on the router.

To update the device software, please make sure:

1. the phone is in the same Wi-Fi network with the device
2. the device is turned on and connected to a Wi-Fi network
3. there is a stable connection between the phone and the device.

Sometimes the application may say, "Failed to connect to the device. To install updates, your phone must be on the same Wi-Fi network as the devices." Although in fact the phone and the device are in the same Wi-Fi network. This happens when the application considers the quality of the local connection to be bad. This happens when there is a long distance to the router or interference from other devices operating on the same frequency (for example, neighboring routers). In such a situation, it helps to bring the phone closer to the router and / or wait and start the update procedure again in a minute or two.

If it is not possible to bring the device closer to the router (for example, an air conditioner), then there is a life hack - remove the Wi-Fi module from the device, plug it into any USB adapter to charge the phone, and plug the adapter into a socket next to the router. Connect Wi-Fi module to the application. It will display as WFN-02. Update software on it. Plug it back into the device

Geolocation is needed to determine the weather and air quality (for air cleaners). And also for connecting devices. In theory, you can put a geopoint on a room during setup only, but then this geopoint will be stored on the server, and we carefully avoid storing important personal data of users. The geolocation does not drain the battery if applications are given permission to use it only while using the application.

The code is not sent if your mail server or mobile operator considers the message to be spam. Try another address or another authorization method

The application only shows what the device sends to it. Not everything that it sends to his screen, it gives to the application also.

This can happen with devices that can connect on both 2.4 GHz and 5 GHz, and your networks on these frequencies are named the same. We recommend calling the networks different names. And it is good practice to create a separate 2.4 GHz Wi-Fi network for IoT devices without access to devices in other networks.

1. One of the automatic modes has worked in the device.
2. Schedule has worked in the device.
3. Some other account also has access to control the device (you can see it in the Rights Control section).
