This device uses WB2S module which needs to be replaced with ESP-02S, WT-01N or WT32C3-01N. Besides the module, this process will require a heat gun, soldering tools and moderate soldering skill.

Disassembly tips:

Be careful when you remove the glass plate as I broke the catches.

You should have to enlarge the ground screw hole, as the screw will not allow the pcb to come out.

The PFS smart plug comes with a Tuya WB2S chip, you can simply remove it and replace it with a TYWE2S (ESP8285) chip, as they are essentially identical.
