WB3S replacement for Home Automation devices

More and more home automation devices from China are coming with no ESP8266 module, especially the TUYA based ones. Some are coming with a WB3S (which is different to the TYWB3S), but this can easily be removed and replaced with a cheap ESP12F (or similar) module.
