Problem with the generic lamp Tuya does not connect to wifi and does not blink

Buy 3 generic lamps by Aliexpress that connect by Smartlife, I could configure them to 2 without problems, but one, it does not make a slight flashing like the others and I can not connect it to wifi, I made countless hard reset (on-off) but None worked, I’m very new to this and I don’t know if there will be any solution, I hope your answers, thank you very much

the lamp turns on and off like a normal led lamp

if all three lamps are the same, and one wont even pair to the app and wifi, it is probably faulty

Is there any way to repair it with a hard reset or a flash?

if you are happy to flash it yourself, you might as well try the various tasmota posts on here.

I’ve not tried, as I’m nervous bricking my light switches…

How do you expect anyone to know how to reset it without even telling us what exactly you bought?

Thanks for your answers, but in this special case, he’s almost dead, that’s why it’s worth flashing there, hahaha

sorry, I’m new to this, this is what I bought, and I can’t pairing it

I bought 3, 2 I could pairing them, but one does not make any flashes
