10Pcs ESP-01S Relay Module WiFi Smart Remote Switch Phone APP DIY Project Design
US$17.24 US$23.99

Q: Did you make sure to use ESP-01S. THAT IS VERY IMPORTANT. It is very different than the ESP-01. Research the ESP-01S it does not need chip enable so the relay board does not supply it. the 2N7000 on the board is a mosfet so the schematic for the relay board is incorrect.

Takes quite a lot of rework to get this device to function, see on you tube how to fix the relay. I wouldn't recommend this device
