Tuya Setti Sms603/ Sws-s001/ Blitzwolf WS02 weather station Wi-Fi module not working [CB3S]

Hello to all forum members. This is my first topic on this forum, so please be understanding🙂 .
I have a problem with my Tuya Setti SMS603 weather station (twin models are: sws-s001, Blitzwolf ws02). Well, after a power outage (about 3 times in a few minutes) the station stopped connecting to the Tuya app, the Wi-Fi symbol disappeared on the screen and it fails to put the station into pairing mode (it has a physical button for pairing - you hear a sound that it should be ready to pair, but the Wi-Fi sign doesn't flash on the screen and the Tuya app doesn't see it). I managed to take it apart to see what module is inside - Cb3s. Has anyone had a similar case and managed to solve it? I am sending pictures of the station and the interior. Thank you in advance for your help 🙂
AI: Have you tried doing a factory reset of the weather station (if one is available)? If so, did anything change after the reset?
Yes, the station beeps but the Wi-Fi module does not work, the app does not detect it
AI: Apart from the Wi-Fi problem, does the station work properly - displays weather data, responds to other buttons, etc.?
Yes

You can see the full wifi range glowing in the picture. If properly connected, the clock will synchronise. The programme connects via Bluetooth. The 7w1 came to me 2026.03.19 Thursday. The display is powered by 5V via USB and in case of power failure 3 R6 batteries not inserted. In the absence of a wifi connection it lights up all the time and flashes the range for two dashes.

The first picture is a picture of the box. Since I have a connection problem, the Wi-Fi icon does not display at all. I have the version that is only powered by the charger.

Do not connect the wifi symbol with pairing, as this connection works after the programme has made changes.
