Buy Geekcreit ESP8266 5V WIFI Relay Module Internet Of Things Smart Home Phone APP Remote Control Switch best price
LC 5V WiFi relay module carried a ESP8266 WiFi module and microcontroller.
It will send the serial port instructions to the cell phone APP and Implementation within the local area network (LAN) for wireless control relay.
Function and characteristics:
Onboard ESP8266 WIFI module, AP mode 5 client can be connected at the same time;
Module has two work modes: 1, cell phones, carry on the WiFi module;2, mobile phone and WiFI module
Carrying on the same router, by mobile phone APP to control relay
1.The open environment, the mobile phone when carrying on the WIFI module maximum transmission distance of 400 m
2.When the WiFI module and cell phone carrying on the router at the same time the signal transmission distance in accordance with the router On the weak
Onboard 5 v, 10 A / 250 v AC 10 A / 30 v DC relay, absorb 100000 times continuously
Module with diode effusion protection, short response time
Module baud rate: 9600,8,1,0,0.
The board function description:
IN +,IN-: 5 v power input
TX ,RX and GND: a serial port debug pins
Onboard the ESP8266 WIFI module has three work modes: STA (client), AP (hot), the STA + Ap( hot +client), according to the workings of a module to the corresponding choice of WIFI module working mode.Module need before use serial debugging software and USB to TTL module send serial command was carried out on the WIFI module configuration (don’t power outages after configuration is complete, as some of the parameters of WIFI module cannot be saved when the power is cut off), mobile phone and WIFI module after establishing a network connection can use the phone APP control relay.
When cell phone equipped with WiFi module sends commands in the following order:
(The default baud rate 115200)
1, AT+CWMODE=2, namely AP mode is selected;
2, AT+RST, reset;
3, AT+CIPMUX=1, open multiple connections;
4, AT+CIPSERVER=1,8080, configure the TCP server, set the port;
5, AT+CIOBAUD=9600 set the baud rate to 9600. (working in relays to control the baud rate 9600)
6, AT+CIFSR to view the AP mode IP address, such as: the APIP, ‘192.168.4.1’;
7, Cell phone WIFI signal connection name starts with AI-THINKER or ESP8266;
8, In the ‘TCP connection’ address and port into the APP, such as 192.168.4.1 and 8080;
9, Click on the grey box relays can be controlled.

Its very good item for me, usually I am using this for charging my power bank (10000mah). Very good.
Excellent android box
I bought one for us. And to be honest I was VERY SCEPTICAL. But once installed the sky is the limit on what you can do. Our kids are grown with their own children and even the grandchildren know how to operate it and love the video options. So we decided to get them their own and not to brag but mom and dads gift were the bomb. Even the grandchildren were excited
A+ If you use the right cup!
After having it for a few days I love it! I tried it with different cups and mugs and you’ll want to use the a mug with a flat base to really spread the heat. I pre heat my mug while my coffee brews and it will stay hot as long as you’d like. I found the default high heat setting worked best for me. It’s not to expensive and makes a great gift. I got mine in black and it looks great on my desk at work.
Yes, it works!
This thing really works. If you are reading a review that says it doesn’t then they r either not using it correctly or using the wrong product. I did not get paid to use this product or my personal opinion like others. I didn’t want to spend all the extra money on a fancy brand name with the same results. My pics will speak for themselves.
Perfect nothing to say and accurate data super
Thanks to seller send fast
Lightly box is pressed in brightness, but writing data is no problem four yo ~
Arrival a few days before the scheduled date, very satisfied. Well packaged, received intact and functional, perfect for sketches, simple design but good for the price. Comes with an anti-loss strap, and the pen easy to store.
I arrived a week earlier than planned, I loved it coming with the battery included, very good product
It didn’t take long to get there, all ok
