DIYmall ESP32S 4 Channel Wifi Bluetooth Relay Module FZ2707
ESP32S 4 Channel Wifi Bluetooth Relay Module
Input: 6V 0.750A
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

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. http://192.168.1.1/h1 (activate relay 1), http://192.168.1.1/l1 (deactivate relay 1), http://192.168.1.1/j (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
