Blow Smart Switch with Tuya - how to manually add, does not detect 6m from Wi-Fi

Gentlemen, I have a problem. I wanted to connect myself a blow smart swith relay with the Tuya app and it won't search for me for a stick. I seem to have it connected correctly, I attach a picture - briefly bypassing the relay the halogen lights up. Question is how do I add this relay manually in the app? Step by step, because I don't know which relay to choose, I've tried several and it doesn't find anything. The relay is located in a tin box about 6 meters from the WiFi, maybe the signal is already weak and does not catch ?


AI: Are you sure the relay is in pairing mode (i.e. the LED is flashing) and you are adding it to a 2.4 GHz Wi-Fi network, not 5 GHz?
There is no diode

I have a very similar one - from Chinese. On the back you have a button. You have to hold it down for at least 5 seconds and the device will enter pairing mode, then the phone will detect it for you.
