This project is simple upload and switch stuff on and off over your own wifi network. Switching is limited to your own personal choice. WEMOD D1 have 9 pins you can use as switches. Yes there are many code doing that.
Arduino IDE with ESP8622 libraries installed.
What you will need:
1 x WEMOS D1 mini or ESP8622-01 or 12 WEMOS is just easier.
1 x 8 port relay or smaller
Lots of some colorful wires to hook up WEMOS to you relay module.
Intro:
This is fully working wi-fi switch. By using relay to switch on stuff over you network using the WEMOS. But it will work on ESP-v12 and ESP-v1. With some small changes. Like pin outs.
This is just my code. I did use lots of other people work to finish this project. Wish I remembered all of them for credits. Most is the examples that came with esp libraries, just mixed into code to work. The electronics is simple enough. I used a 8 port relay module and a WEMOS D1 MINI.
Connection:
Notice the relays green jumper! Remove it. The JD-VCC PIN is 12 Volt to pull relay in. Check this pin with the module you have.
| Wemos D1 mini | Relay Module |
| GND | GND |
| VCC 5 Volt from Wemos | VCC |
| D1 | Pin1 |
| D2 | Pin 2 |
| D3 | Pin 3 |
| D4 | Pin 4 |
| D5 | Pin 5 |
| D6 | Pin 6 |
| D7 | Pin 7 |
| D8 | Pin 8 |
| A0 not used yet. Want to use it to monitor battery power. |
Short Explain
The WEMOS have 9 digital pins. D0 to D 8 used to switching relays on and off.
AP is use to setup the WEMOS to go on your home WIFI network.
Don't upload code if relay module is connected.
The Version 1.4
/*
This code is for WEMOS D1 ESP8266 version 2.0
- The code start by checking if settings is in EEPROM
- If not it will write defaults in. Then connect to the Access Point to setup for your WIFI
- If you do not see the AP name WIFIcreations. Restart WEMOS
- In browser address bar type 194.168.4.1 this is AP IP
- After setup WiFi and password click save!! Click restart and WEMOS will connect to the your WIFI
- WIFI IP check in router for the IP. Open browser, add IP and it should open the page
- Click button and it will switch on something
- To go back to AP mode Switch your router OFF. restart WEMOS wait 10 seconds. Go into AP mode. Router ON
- Else clear the EEPROM
- default EEPROM is at end of the code.
