    This is a great module that combines the ESP8266 with 2 relays and an AC-DC converter. An additional plus is the case and the exceptional affordable price!
    I have 2 of these modules integrated at home with my customized firmware. So far they are doing a good job. Some experience with ESP8266 modules is very useful.
    Thank you for this amazing module.
