1、DIYmall ESP32S 4 Channel Wifi Bluetooth Relay Module  

Input: 6V 0.750A (NOTE: if the board can not work, please change power to 9V 1A or 12V 1A)
Relay capacity (per relay): 250Vac/10A, 125Vac/10A, 30VDC/10A
Relays: 4 independently controlled via ESP32
Interface: Bluetooth and Wi-Fi

The relays can be switched on and off individually via BLE or Wi-Fi connection. Upon startup, the module creates a WPA2 protected Wi-Fi access point and BLE server. Over Wi-Fi, the relay states can be controlled with a simple GET statement for easy integration with your applications. The Wi-Fi webserver provides a JSON interface for relay states. A Bluetooth GATT server is created and can be used concurrently with the Wi-Fi access point.

Wifi connection, the wifi name is TEST, password is 123456789

IOS APP: The "DIYMall Relay Control" app in the App Store and Play Store are able to control the relays both over Wi-Fi and Bluetooth
Android APP: https://play.google.com/store/apps/details?id=me.stratux.relaycontrol&rdid=me.stratux.relaycontrol
Requires Android : 4.1 and up

Questions and Answers
1. Does this module include a web server?
Yes, simple HTTP GET requests to 1) turn on/off module, 2) get states of relays in JSON format

2. Can the module be controlled by a browser on a PC (Firefox / Windows)?
 Yes. (activate relay 1), (deactivate relay 1), (JSON format, information on all relay states)

3. Can the module operate in client state, and connect to my existing AP, so I can control it over my existing LAN?
AP only, but can send the firmware to the user to modify easily to add to client state if the user is advanced (just need usb-to-serial). Requires firmware change.

4. And then, using port forwarding, can I control if over WAN?
If you do the above firmware change and you set up the relay client as the DMZ, yes

2、USB To RS232 TTL PL2303HX Auto Converter Module Converter Adapter For Arduino iBeacon

Adopt imported controller PL2303HX,which can stabilize the flash with high speed
500mA self recovery fuse for protection
