I compared your code with mine line by line and apart from my logger having level set to verbose the wifi settings including the AP and the relay switches blue led on and off instead of the button the code is the same
I’ve reflashed both plugs and still acting the same in logs both are reading 0.033A one has a 15w bulb on and the other is on washing machine drawing 3.9W in standby
I have had to cycle the wifi after reflashing to get them to connect again
